Pereyad become zhorstkogo disk. How to recognize the health status of a hard disk, how to marvel at the SMART (HDD, SSD) display and estimate how long a disk can last

For the re-verification of hard disks, there are useless, cost-free tools, which can help in determining what is being done with a hard disk, if there is a suspicion, what is the problem with it.

An operating system like Windows already has such a feature enabled, like rechecking the disk for pardons that command chkdsk, and also other tools presented below, which can be taken without cost from hard disks and other retailers.

Important: If there is a known problem, you may need to replace the hard disk, otherwise you will not have to pass the verification of one of the tests for the hard disk. For whom it is necessary to follow the program's instructions.

The Seagate SeaTools program is a cost-free program for testing hard disks, available for hard drives in one of two options:

• SeaTools for DOS Supports Seagate or Maxtor drives and works independently of your operating system, running directly from a CD or a USB drive, so running your program is even more annoying.
• SeaTools for Windows- This program should be installed in the Windows operating system. Z її additionally, you can improve the basic and expanded testing of any disks in any virobniks - both internal and external.

Tim coristuvacham, if you go to the SeaTools Desktop, SeaTools Online or PowerMax and Maxtor programs, take care that the name of the higher program replaces all three designated programs. Today's Seagate is a Vlasnik trademark Maxtor.

SeaTools programs from Seagate are the best in their segment. Їх vikoristovuyut for reverification of hard disks at professional computer services, but if so, be a kind of coristuvach can easily speed them up.

The version of SeaTools for Windows works on operating systems from Windows 10 to Windows XP.

The HDDScan program is a cost-free program for checking all types of disks independently from any type.

HDDScan includes a number of tools, including SMART testing and surface verification.

The program is even simpler to use, does not require installation, maintains an interface on all disks, and seems to be updated regularly.

HDDScan can be tweaked on Windows 10, 8, 7, Vista and XP, as well as on Windows Server 2003.

DiskCheckup - cost-free zasib translation of the zhorsky disk, which works with more disks.

The program displays such SMART information, as the number of pardons read, the hour of spinning the package of plates will become calm to work speed, the frequency of pardons when positioning the block of magnetic heads and the temperature. In addition, there may be a change of speed and an expanded re-verification of the disk.

You can adjust the program so that the SMART information is sent by email or displayed on the display, if the disk parameters exceed the threshold values ​​recommended by the dialer.

Only disks that can support SCSI or implement hardware RAID mechanisms are not supported by DiskCheckup.

The DiskCheckup program works on Windows 10/8/7/Vista/XP and Windows Server 2008/2003 operating systems.

The GSmartControl program can perform various re-verifications of a hard disk, displaying detailed results and giving an overall assessment of the hard disk.

To search for disk failures, the GSmartControl program can use three self-verifications:

• Shvidka reverb: takes close to 2 minutes and vikoristovuetsya for the manifestation of a seriously damaged hard drive.
• Extended revision: Approximately 70 minutes are required and the entire surface of the hard disk is checked for failure detection.
• Transport re-check: This re-verification takes 5 minutes and is recognized for a little extra money, as it could be an hour for transporting the disk.

The GSmartControl program may be available for Windows, as in the option without installation (portable), as well as the program, which is installed. It works on system versions from Windows 10 to Windows XP. Also, you can choose the option of the program for operating rooms Linux systems and Mac and programs in LiveCD/LiveUSB format.

Windows Drive Fitness Test - no cost software security for diagnostics of hard disks, building on more available disks.

Unfortunately, for the help of Windows Drive Fitness Test, you can change it less USB drives and other internal disks.

The WinDFT program can be installed on Windows 10, 8, 7, Vista and XP operating systems.

The Samsung HUTIL program is a cost-free utility for diagnosing Samsung hard disks. The HUTIL code is called ES-Tool.

The Samsung HUTIL program is available as an ISO image for further burning to CD or USB flash drive. Such a way to work HUTIL with an independent type of operating system, zagal, a handy tool for testing, lower programs, expanding the Windows operating system. It is also possible to run HUTIL from an advanced floppy disk.

Note: HUTIL program to change only hard disks Samsung. It is worth looking into and knowing disks not manufactured by Samsung, but such disks cannot be used for any diagnostics.

Oskilki Samsung program HUTIL works from an exciting disk, then for the robot it is necessary to have a hard disk, which is functioning, and an operating system, to write it to a CD or a USB flash drive.

The cost-free Western Digital Data Lifeguard Diagnostic (DLGDIAG) program has been decommissioned for the verification of excess hard drives bearing the Western Digital trademark.

The Western Digital Data Lifeguard Diagnostic can be enchanted as a portable version for Windows, and it looks like an ISO file with a way to burn to an enchanting disk, and it also checks for a number of hard disk conversions. Detailed instructions by installing Western Digital, you can find out by asking, hovering below.

Note: The DOS version of DLGDIAG does diagnostics only on Western Digital disks, while the version of this software for Windows works with disks of other diagnostics.

The version of the program for Windows works on operating systems with Windows 10 Windows XP

Bart's Stuff Test

Bart's Stuff Test Program no-cost program for Windows navantage test hard disks.

The program does not give such a large number of possibilities and does not carry out a thorough test of the hard drive, like other programs in this list.

Thank you for your efforts, Bart's Stuff Test is a great addition to your arsenal of disk verification, especially as you can see the difficulties of verification for additional benefits based on ISO-images, and you want to speed up for more, for the sake of it. Windows.

Bart's Stuff Test, as stated, works only on operating systems from Windows XP to Windows 95. However, we checked the practice on the remaining versions of the system (Windows 10 and Windows 8) and did not reveal any problems.

Fujitsu Diagnostic Tool is a cost-free tool for diagnosing hard disks, developed specifically for Fujitsu hard disks.

The Fujitsu Diagnostic Tool (FJDT) is available in both Windows and DOS versions with optional floppy disks. Unfortunately, the DOS version of the orientation on floppy disks - images that run from CD or USB are not available.

Fujitsu Diagnostic Tool gives two revisions: "Swedish test" (trivality is close to 3 minutes) and "All-sided test", which is the hour of any old hard drive).

Note: The Fujitsu Diagnostic Tool scans hard disks only for disks released by Fujitsu. If you have a disk that looks like a different brewer, then it is necessary to try the hacking programs, so as not to lie in the scribe, hover over the top of the list.

Version for Windows programs Fujitsu Diagnostic Tool can be run on all operating systems from Windows 10 to Windows 2000.

The HD Tune program converts hard disks, working under Windows corrections. Won can pratsyuvati s be-yakim vnutrishnіmi or old discs, SSD drives or memory cards.

For the help of HD Tune, you can run a productivity test, rewrite the disk camp for the help of the Self-Monitoring Analysis mode (monitoring analysis) and the technology of sounding about the disk robot (SMART). In addition, the program can scan the disk for pardons.

Works on Windows 7, Vista, XP and 2000 systems, although HD Tune works correctly on Windows 10 and Windows 8.

The program Free EASIS Drive Check, recognized for rechecking hard disks, may have two rechecking utilities - rechecking sectors and reading the value of SMART attributes.

The SMART attributes check allows you to compile a list of over 40 parameters that describe the work of a hard drive, and the sector check allows you to check the surface of the wear for pardon reading.

Sounds about vikonannya, whether any of these tests, you can chat without interruption at the program after completion. In addition, you can adjust the program in such a way that it sounds like e-mail otherwise, looking at each other.

According to the description, EASIS Drive Check works on operating systems from Windows 2000 to Windows 7, but it is reversed to work on Windows 8 and 10.

The pardon conversion program is sometimes called the scandisk program. Tse zasіb reverification of the hard disk, which is to enter the operating room warehouse Windows systems, and that allows you to search for various pardons on a hard drive.

Tsey zasіb also can succumb to low problems associated with a hard disk.

Macrorit Disk Scanner is a very simple program that checks the presence of bad sectors on a hard drive. It's easy to tweak, it's easy to install, and it's also available in a portable version.

The main part of the image is victorious for a visual presentation to the scanning process and is clearly indicated on the spot of error.

Macrorit Disk Scanner is especially well-implemented visually showing how long it took before the end of the recheck, because some programs of reverification of hard disks do not show this. In addition, you can select the option to automatically wake up the computer after the verification is completed.

Operating systems in which Macrorit Disk Scanner can be used are: Windows 10, 8, 7, Vista, XP, Windows Home Server and Windows Server 2012/2008/2003.

Ariolic Disk Scanner is similar to Macrorit Disk Scanner in that it takes no more reading to search for bad sectors on the disk. This program has a minimal interface with a single button, and, vikoristovuyuchi її, it is easy to understand, like parts of the disk to avenge the "beat" sectors.

The program can only be a portable version, and її rozmir trohi move 1 MB.

The only ones that run the program like Macrorit Disk Scanner, those that Ariolic Disk Scanner shows files that have read pardons.

We have tested the Ariolic Disk Scanner robot only on Windows 10 and XP, but it can also work with other versions of Windows.

Rich koristuvachіv navit not to follow the camp of a hard disk, but darma. HDD - all attachments, on which all your information is stored. When you die, you spend all the money, as you knew on your nose.

At the article, I'll tell you how to turn over the camp of a hard disk for the help of hard, but simple programs. With some kind of program, swear by yourself after I look around. But my thought, one program is a good addition, and I recommend that you speed it all up, for more information about the camp of your hard drive.

Maybe, the simplest and most convenient program for rechecking HDD / SSD - CrystalDiskInfo. Everything you need to convert the hard disk, just run the program and look at the SMART displays.

As one of the criteria for instability, the program in the same category of pardons and lighten up your life or red color. Let me briefly explain the meaning.

1. The interface header has tabs for selecting hard disks. By clicking on these and other tabs, you can look over the camp of the skin. If you have an HDD connected, you can check them out by wondering at the model, or else.
2. Under the header there is a button Tehstan and Temperature. It’s worth talking about the blazing camp of a hard disk, or maybe a black color booty - good, yellow - Alarm!, red - Poor!. The temperature should ideally be over 45°C.
3. Show a pardon in a specific SMART category.

In the caption under the written hard drive model you can find out the detailed information about your nose: for HDD - data buffer, speed of wrapping of magnetic disks, turn on time, hot hour of work; for SSD - ce host-read, host-records, NAND-records, turn-on number, working hour.

You can also check the firmware version serial number, maybe in good time for those who are looking for a donor, but the information is not enough.

The program supports connection via USB, SATA, RAID. It can be installed on all current Windows platforms, starting with XP and ending with 10.

Not a moment to tell about Hard Disk Sentinel, you will add another program for testing a hard disk, give a more detailed assessment of the technical state.

Run the program, select your disk and look at the information on the tab looking around. Varto zvernuti respect for health, temperature, productivity, and awareness, as ordered by the frame. In order to understand the meanings, use the arrows in the bottom screenshot.

The functionality of the Hard Disk Sentinel program is great, but within the framework of the article, we consider only those that need to diagnose a hard disk.

How to flip sectors on a hard drive

Maybe, by yourself popular program for rechecking sectors on a hard drive Victoria. You can look at the SMART status, check the blocks for consistency and readability. As I already described.

Stan HDD filth? Get the data!

As soon as a hard disk test has shown that it has become critical, copy all the information to another disk in a term. Often, coristuvachi do not give great importance to hanging, mimicry re-engagement of the computer. As a rule, it's better to put the power on only once, if you stop bothering Windows. For an hour, it’s too bad, to get information independently. It's not necessary hardware repair and replacement of components for the help of a donor, you can try.

Although there are bits of sectors on the HDD, you can try them out by reassigning them to another area for help. The ideal program for which task will be HDD Low Level Format. Respect! This procedure sees all your information without the possibility of renewal. Move the data forward to another nose.

If you have problems with the mechanical part of the HDD, please read this article. I guess, the article helped a lot of readers. To blame the food, put it in the comments.

The camp of some kind of call to you suspects, first, what is needed to be done, in order to reverse the data of SMART technology. This technology is recognized for the collection of information about the hard disk mill and the self-diagnosis procedure. For the help of SMART, you can quickly evaluate whether a hard drive is found in it, how much data you need to spend, and what work is needed for further diagnostics and computer repair.

SMART technology (or S.M.A.R.T.) appeared on hard disks in 1992. One of the first accumulating systems was a disk array from the IBM company. From that hour, SMART took off a wide zastosuvannya and at the same time vikoristovuetsya absolutely in all HDDs and most SSD disks.

The interface of the CrystalDiskInfo program is simple and easy to understand. The upper part of the window contains a list of disks connected to the computer. After selecting a hard drive, all the information available for that HDD will appear in the lower part of the window.

Trochs lower than the spreading block of basic information about accumulating money. Here you can find out the name of the disk, the version of the firmware, the serial number, the interface, the speed of the spindle wrap, the turn-on number, the working hour, and also other information.

In the block with the main information, the most important data are “The number of inclusions” and “The main hour of work”. The greater the value, the greater the size of the hard disc, the shards in the process of robotic wine will inevitably degrade. On modern computers, modern disks sound normally for 15-25 thousand years, after which problems begin to appear. For laptops, the number is even less, where the disks sound no more than 10-20 thousand years.

Closer to the left part of the window there are two more important parameters. Tse otsіka tekhnіchnogo stan zhorstkogo disk and yogo temperature. Evaluation of the technical standard of a hard disk is a final assessment, as the program hopes to be based on the data of SMART technology. This assessment can take one of three values:

• Good - with a disk, everything is good, everyday life is not needed.
• Trouble - the disk may have some problems, varto check the presence of backup copies, the disk should be replaced.
• Bad - the disk may have significant errors, the disk needs to be replaced.

I can’t have a direct relationship to yoga. The normal temperature for HDD is between 20 and 45 degrees Celsius. If the temperature exceeds 45 degrees, it's not enough to talk about bad cooling of the computer case.

The most detailed information about the mill of the hard disk can be found in the lower part of the program window. Here is a list of parameters, which are based on SMART technology, as well as given values. Vykoristovuyuchi tsyu іnformatsiyu, you can quickly evaluate the HDD camp and make decisions about further steps.

When scrolling through the list of SMART parameters, the value of the “RAW-value” column is displayed next. Data specified in HEX format.

The list of parameters that are supported by SMART technology is great, but not all of them can be critical for a hard drive. Below we will look at the least important of them.

• 03 - Spin-Up Time- an hour, which is necessary to spin the disk from a turned-on I will become a worker. Price value increases when the mechanical part of the accumulator is worn out, so the great hour of the spin-up can be evidence of the voltage drop when the disk is started.
• 05 - Reallocated Sectors Count- the number of sectors, which were found to be invalid and reassigned to the reserve area. The presence of reassigned sectors indicates problems with the disk surface.
• 0A – Spin-Up Retry Count- the number of repeated samples of the spinning of the disk. The value increases when the mechanical part of the accumulator is worn out.
• BB - Reported UNC Errors- a lot of pardons, yakі far away to put the accumulators with the help of the apparatus.
• BC - Command Timeout– number of operations that were interrupted after a timeout. An increase in this parameter may indicate problems with the recovery of the disk or cables.
• C4 - Try Sector Reassignment (Reallocation Event Count)– number of samples to set the sector reassignment operation. Rahovuyutsya as far away, and not far away, try reassigning sectors. The presence of samples reassigned indicates problems from the surface of the disk.
• C5 - Unstable sectors (Current Pending Sector Count)- the number of suspected sectors, which can be reassigned to the future one. The presence of unstable sectors indicates problems with the surface of the disk.
• C6 - Uncorrectable Sector Count- a number of sectors, which cannot be corrected by the hard drive. The presence of incorrect pardons indicates problems with the surface or mechanical part of the disk.

Although the value of RAW for all other parameters is set to zero, it indicates those that the hard disk is known to be at the control station. The SMART technology did not reveal any everyday problems. Even though some parameters may be greater than zero, the HDD varto can be changed more significantly, possibly, such a disk needs to be replaced.

The most important SMART parameter is the "Reassigned Sectors" or "Reallocated Sectors Count" parameter. Vіn specifying the number of bad sectors, which were recognized as a disk in the reserve area. Sound, after the appearance of all the reassigned sectors on the surface of the disk, it starts to degrade quickly and accumulate again to get out of tune in a few days.

Therefore, when reassigning sectors is revealed, it is necessary to check the presence of backup copies of all important data that are saved on such a disk. Although there are no backup copies, it is necessary to keep the term, otherwise you risk spending data.

It’s too early (better, swankily, yakscho early) whether it’s a kind of coristuvach to put your own food about those, as if it’s a longer stretch for the new one to computer hard disk i chi not an hour to look at you zamin. There is nothing marvelous about it, but the hard disks due to their design features are the least of the computer components. At the same time, on the HDD, most of the hard disks save the left part of the most interesting information: documents, signs, different programs, etc. Obviously, often information on the call of "dead" hard disks can be found, but it is not turned off, what operation to fly you "at a penny", that and nervously koshtuvatime chimalih. That's why it's more effective to try to save money.
Yak? First, don't forget about regular backups of data, but in a different way, control the camp of disks for additional specialized utilities. Dekіlka programs of such a plan from the perspective of rozv'yazuvanih zavdan mi and look at this article.

Control of SMART parameters and temperature

All modern HDDs and solid-state storage devices (SSDs) support S.M.A.R.T. ( English Self-Monitoring, Analysis, and Reporting Technology (technology for self-monitoring, analysis and zvіtnostі), as a bula was broken up by the main hard disk manufacturers to increase the reliability of their products. This technology is based on non-stop monitoring and assessment of the hard drive with self-diagnostic equipment (special sensors), and its main recognition is its own manifestation of a possible exit from the accumulating state of harmony.

Monitoring will become HDD at real time

A number of informational-diagnostic solutions for diagnostics and testing of "freezing", as well as special monitoring utilities for vicorist technology S.M.A.R.T. to watch over the production line of various life important parameters that describe the superiority and productivity of hard discs. They read the parameters directly from the sensors and thermal sensors, which are equipped with all modern hard disks, analyze the taken data and display them in a short table with a change of attributes. What part of the utilities ( hard drive Inspector, HDDlife, Crystal Disk Info (simply) do not intermingle with attribute tables (the values ​​of which are not understood for unprepared hard disks) and additionally display short information about the disk camp more accessible to the mind.

Diagnosing hard drive status for help with this kind of utilities is as easy as shelling pears - get familiar with the short basic information about installed HDDs: with the main data about disks in Hard Drive Inspector, a smart indicator of the health of a hard drive HDDlife, the "Tekhstan" indicator in Crystal Disk Info ( 1) and so on. Whether any of these programs should have at least the necessary information about skin problems installed on computer HDD: data about the Winchester model, yoga, work temperature, work hours, and also the level of reliability and productivity. This information gives the possibility of growing the singing of the visnovka to wear practicality.

Mal. 1. Brief information about the "health" of the HDD robot

Next, adjust the launch of the monitoring utility one hour after the start of the operating system, adjust the time interval between rechecks of S.M.A.R.T. If you want to control the state of disks of coristuvachev, you will have to look at the indicator in the system tray for an hour every hour, so there will be short information about the state of the accumulators that are obvious in the system: the level of their “healthy” temperature (Fig. 2). Before speech, working temperature - not less important indicator of lower mental indicator of HDD health, even more hard disks can easily get out of tune after a banal overheating. Because the hard disc heats up more than 50 °C, it would be wiser to provide additional cooling.

Mal. 2. I will become a hard disk
in the system tray with the HDDlife program

Warto signify that in a number of such utilities integration with the Windows Explorer is transferred, why on the icons of local disks, in some cases, the icon turns green, and when there are problems, the pictogram turns red. Also, forget about the camp of healthy hard disks, you are unlikely to get into it. For such constant monitoring, you won't be able to miss a moment if there are problems with the disk, even if the utility has detected critical changes in S.M.A.R.T. attributes. and/or the temperature will tell you about the sound of the speaker (indications on the screen, sound notifications, etc. - small 3). Zavdyaki to whom you can catch up to copy the data from the nose, which instills a fight, in advance.

Mal. 3. An example of a reminder about the need for a non-gain disc replacement

In practice, the solution to S.M.A.R.T.

Control of S.M.A.R.T.-attributes

Prosnutі koristuvachі, zrozumіlo, hardly swear for evaluation I will become hard disks reviewing a short verdict of one of the utilities. Vono figured it out, even after deciphering the attributes of S.M.A.R.T. you can identify the cause of the failure and, if necessary, take it in again if necessary. True, for independent control of S.M.A.R.T. attributes, it is necessary to briefly familiarize yourself with S.M.A.R.T.

To the warehouse of hard disks, which support this technology, and the inclusion of intelligent self-diagnosis procedures, the stench of the building "reminds" about its in-line mill. This diagnostic information is hoped as a collection of attributes, so that specific characteristics of the hard disk, as a basis for analysis of productivity and reliability.

B about The most important attributes may be the very sensation for discs of all virobniks. The values ​​of these attributes under normal disk operation can change in certain intervals. For any parameter, the virobnik is assigned the minimum safe value, as it cannot be overstated for the normal minds of exploitation. Definitely assign critically important and critically unimportant parameters for the diagnosis of S.M.A.R.T. problematic. The skin of attributes may have its own informational value and be aware of that other aspect of the robotic nose. However, we should pay attention to the following attributes:

• Raw Read Error Rate - frequency of pardons for reading data from the disk, which is caused by fault;
• Spin Up Time - the average hour of spinning the disk spindle;
• Reallocated Sector Count - the number of operations to reassign sectors;
• Seek Error Rate – frequency of appearance of positioning pardons;
• Spin Retry Count - the number of repeated attempts to spin up disks to a working speed in case of failure of the first try;
• Current Pending Sector Count - the number of unstable sectors (these are the sectors that will qualify for the reassignment procedure);
• Offline Scan Uncorrectable Count - total number of uncorrectable pardons per hour of operations for reading/writing sectors.

Ring out the attributes of S.M.A.R.T. are displayed in the table view from the assigned attribute name (Attribute), the first identifier (ID) and three values: the stream value (Value), the minimum threshold value (Threshold) and the lowest value of the attribute for the entire hour of work and accumulation (Worst), as well as the absolute value of the attribute ( raw). The skin attribute can have a more precise value, as it can be a number like 1 to 100, 200 or 253 (there are no higher standards for the upper inter-value attributes). The Value and Worst values ​​of a completely new hard drive are different (Fig. 4).

Mal. 4. Attributes of S.M.A.R.T. on the new HDD

Shown in Fig. 4 The information allows the generation of visnovs, which theoretically correct hard drive stream (Value) and higher (Worst) values ​​are as close as possible one to one, and the Raw value for most parameters (with a few parameters: Power-On Time, HDA Temperature and others) may approach zero. More precisely, the value can be changed from time to time, which in the majority of cases shows an improvement in the parameters of the hard disk, which are described by the attribute. You can look at fig. 5 shows fragments of tables of attributes S.M.A.R.T. for the same disc - data taken from the interval at the pivroku. Like Bachimo, the newest version of S.M.A.R.T. the frequency of pardons when reading data from the disk (Raw Read Error Rate) increased, the frequency of pardons when the block of magnetic heads was positioned (Seek Error Rate), which, perhaps, could indicate about the overheating of the hard drive and its position in the cat . If more precisely the value of some kind of attribute is approaching, or becomes less than the threshold, then the hard disk is found to be undesirable, and the next term should be changed. For example, if the value of the Spin-Up Time attribute (the middle hour of spinning the disk spindle) is lower than the critical value, as a rule, it means that the mechanics are worn out, after which the disk is no longer able to increase the speed of the wrapping. Therefore, it is necessary to control the HDD and periodically (for example, once every 2-3 months) carry out the diagnosis of S.M.A.R.T. and save the information in text file. Given these data, you can compare them with the current ones and add more songs to the development of the situation.

Mal. 5. Tables of attributes S.M.A.R.T.
(new version of S.M.A.R.T. below)

When looking at S.M.A.R.T. I will become an attribute of the visionary utility S.M.A.R.T. The table of wines should be marked in a different color, which will make the situation easier to understand. Zocrema, in the Hard Drive Inspector program, the color indicator can be green, yellow-green, yellow, orange or red color - green and yellow-green color to talk about those that everything is fine (the value of the attribute did not change or was not changed), but yellow, orange and red colors signal about a problem (the most red color, which is to say about those that the value of the attribute has reached its critical value). As a result of the critically important parameters indicated by the red color badge, it is necessary to replace the Winchester by the term.

Let's take a look at the table of S.M.A.R.T.-attributes of the same disk in the Hard Drive Inspector program. 3 fig. 6 shows that the values ​​of all attributes in the norm and all parameters are marked with green color. A similar picture can be shown by HDDlife utilities and Crystal Disk Info. True, more professional solutions for HDD analysis and diagnostics are not loyal and often mark S.M.A.R.T. attributes more quickly. For example, such utilities, like HD Tune Pro and HDD Scan, have been set to the UltraDMA CRC Errors attribute in our case with suspicion, which shows a lot of pardons that are blamed for the transfer of information external interface(Mal. 7). The reason for such pardons is due to a twisted and inaccurate SATA cable, which, if possible, should be replaced.

Mal. 6. Table of S.M.A.R.T.-attributes, taken from the Hard Drive Inspector program

Mal. 7. The results of the evaluation will become S.M.A.R.T.-attributes
HD Tune Pro utilities and HDD Scan

For a better understanding of the S.M.A.R.T. The Crystal Disk Info program did not install the wine - in the "Tehstan" indicator, the disk was rated as alarming, and the Reallocated Sector Count attribute (Reassigned sectors) appeared as a bright yellow color (Fig. 8). It is also an attribute that is important from the point of view of disk health, which indicates the number of sectors reassigned when the read/write pardon is detected by the disk; during this operation, data from the damaged sector is transferred to the reserve area. The yellow color of the indicator in the parameter to talk about those that reserve sectors, which can replace the crashes, has been lost a little, and it’s not hard to reassign the crashed sectors again to nothing. It is also reconsidered, as to assess the size of a disk of a serious decision, for example, the HDDScan utility is widely recognized by professionals, - but here we have the same result (Fig. 9).

Mal. 8. Evaluation of a problem hard disk CrystalDiskInfo

Mal. 9. Results of HDD S.M.A.R.T. diagnostics in HDDScan

So, from the replacement of such a hard disk, it is clearly not hard to pull, although you can serve the operating system for an hour. danish zhorsky you can't install the disk, obviously. Varto signify that due to the presence of a large number of reassigned sectors, the speed of reading / recording falls (after the folds of the ruhіv, as it happens with the magnetic head), the disk is repaired.

Surface scanning for bad sector

Unfortunately, in practice, one control of SMART-parameters is not enough for that temperature. When other information appears about those that are not working with the disk (for example, if the program freezes periodically, for example, if the results are saved, you will receive a warning about the pardon of the reading then), it is necessary to scan the surface of the disk for the presence of sectors, which is not readable. To carry out a similar verification of the nose, you can speed up, for example, with HD Tune Pro and HDDScan utilities, or with diagnostic utilities such as hard disks, but the utilities can only work with their own models of hard disks, and we can’t see them.

When vikoristanny of such solutions, there is a risk of data loss on the disk, which is scanned. From one side, from the information on the disk, if the accumulated data can be found to be incorrect, the next hour of scanning can be good. On the other hand, it is not possible to turn off incorrect data from the side of the coristuvach, which promptly starts scanning in the recording mode, during which sector-by-sector erasure of data from the hard drive is performed with a singing signature, and on the basis of the speed of this process, the visnovok of the disk is scrambled. Therefore, it is absolutely necessary to follow the rules of safety: before starting the utility, it is necessary to create a backup copy of the information and during the re-verification of the data strictly according to the instructions of the retailer of the specific PZ. For more accurate results, close all active programs and enable background processes before scanning. In addition, if you need to test the system HDD, you need to start the scanning process from the flash drive and start the scanning process from it, or remove the hard drive and connect it to another computer, and then start testing the disk.

Like a butt for help, HD Tune Pro can be checked on the bad sectors and on the surface of the HDD, which does not instill trusted Crystal Disk Info utilities. For this program, to start the scanning process, it is enough to select the required disk, activate the tab error scan and click on the button start. The next utility scans the disk later, reading sector by sector and indicating sectors on the disk map with different squares. The color of the squares fallow in the situation can be green (normal sectors) or chervonim (bad-blocks) or matime intermediate between the colors of the colors. Yak bachimo from fig. 10, the utility did not know any of the most common bad-blocks in our case, and yet, it is not less evident that there are a solid number of sectors with this chi and other clutter of reading (judging by their color). In addition to the new one in the middle part of the disk, there is a small block of sectors, the color of which is close to red - these sectors are still not recognized by the utility, but the stench is already close to that and go over to the category of the worst at the next hour.

Mal. 10. Scanning surfaces for bad sectors in HD Tune Pro

If you protest against the bad sector of the HDDScan program, it is more complicated, that and unsafe, shards in case of an incorrectly selected mode, the information on the disk will be irrevocably lost. Before starting the scan, create a new task by clicking on the button New Task and choosing the command from the list Suface Tests. We will need to reconsider, which mode is selected read- this mode is set up for locking and for several tests on the surface of a hard disk to be carried out for reading (to do so without having to read data). Next press the button Add test(Fig. 11) and dvichі click on the created task RD Read. Now you can check the process of scanning the disk on the graph (Graph) or on the map (Map) - fig. 12. After the process is completed, we can take approximately the same results as were demonstrated by the HD Tune Pro utility, but with more clear interpretation: there are no bad sectors (they are indicated by a blue color), but in reality, three sectors by value with a black color color), yakі th to become real unsafe. If there are six orange sectors (the hour of the video is from 150 to 500 ms), then it can be entered in the middle of the norm, the fragments of such a jam in the air are most often called out by time shifts in looking at, for example, background programs that are being practiced.

Mal. 12. Results of disk scanning in Read mode with HDDScan help

As an addendum, note that for the presence of a small number of bad blocks, you can try to improve the camp of a hard disk by cleaning up the bad sectors and scanning the surface of the disk in the Erase mode for help HDD software scan. After such an operation, the disk can still be used for an hour, but, obviously, not a system one. However, it’s not surprising to be surprised, the HDD shards have already begun to sulk, and there are no guarantees, but in the next hour a lot of defects are not growing and accumulating, the rest is not out of whack.

HD Tune is a handy utility for diagnosing and testing HDD/SSD (div. table), as well as memory cards, USB drives and other data storage devices. The program displays detailed information about the storage device (firmware version, serial number, disk size, buffer size, and data transfer mode) and allows you to install the S.M.A.R.T. and temperature monitoring. In addition, in addition, you can also test the surface of the disk for the presence of pardons and evaluate the productivity of the attachment by running a series of tests (testing the speed of the sequential and sequential reading/writing of data, the file productivity test, the cache test and a series of Extra-tests). Also, the utility can be used to set up AAM and securely view data. The program is presented in two editions: commercial HD Tune Pro and cost-free, lightweight HD Tune. The HD Tune editors have access to more detailed information about the disk and S.M.A.R.T. attribute tables, as well as scanning the disk for pardons and testing for speed in the read mode (Low level benchmark - read).

For monitoring S.M.A.R.T. For whatever attribute, you can look at the history of this change in the numerical look at the graphics. Data for monitoring are automatically recorded in the beam, but no further updates are sent in case of critical changes in parameters.

What does it take to scan the surface of the disk in case of the presence of random sectors, then for this operation you will see a tab error Scan. Scanning can be quick (Quick scan) and deep - with swedish proofreading not the entire disk is scanned, but rather just one part (the scanning zone is defined through the Start and End fields). Poshkodzhenі sectors are displayed on the map of the disk near the red blocks.

HDDScan - a utility for low-level diagnostics of hard disks, solid-state drives and Flash disks USB interface. The main recognition of this program is the testing of disks for the presence of bad blocks and bad sectors. Also, the utility can be used to review S.M.A.R.T., temperature monitoring and change nalashtuvan zhorstkogo disk: noise grinding (AAM), life grinding (APM), primus start/spindle teeth accumulating and in. The program works without installation and can be run from a portable device, such as a flash drive.

S.M.A.R.T. attributes and temperature monitoring in HDDScan can be performed on the fly. Sound of S.M.A.R.T. to collect information about productivity and "healthy" accumulation in the appearance of a standard attribute table, the temperature accumulates in the system tray in a special information window. Calls can be extracted or saved in MHT files. It is possible to conduct S.M.A.R.T.-tests.

Verification of the surface of the disk is carried out in one of four modes: Verify (linear verification mode), Read (linear reading), Erase (linear recording) and Butterfly Read (Butterfly reading mode). To check the disk for the presence of bad-blocks, sound the test of the reading mode (Read), with the help of which it is possible to test the surface without seeing the data (the visnovo about the camp of the accumulator is trying to see the speed of the sector-by-sector reading of data). When testing in the mode of linear recording (Erase), the information on the disk is overwritten, but the test can add a third of the disk, allowing you to see the bad sectors. For some modes of testing, you can test the entire disk over and over, or the next fragment (the scanning zone is indicated by the combination of the cob and end logical sectors - Start LBA and End LBA, obviously). The test results are displayed at a glance (Report tab) and are displayed on the graph (Graph) and disk map (Map) from the number of bad sectors (Bads) that are assigned to the number of bad sectors (Bads) and the sectors, the hour of which during testing took over 500 ms ) ).

It's a pity, some of today's HDDs normally work a little more than fate, then different problems are fixed, which can lead to a loss of money in an hour. Such prospects can be hidden, as if respectfully following the camp of a hard drive, for example, looking for help from statistical utilities. However, forgetting about regularly backing up valuable data is also not a good idea, as far as monitoring utilities, as a rule, far away predict the failure of a disk from the fault of the "mechanics" (according to statistics from Seagate, through mechanical components, close to 60% of the HDD go out of tune), but stench it is not possible to transmit the death of the accumulator through malfunctions of the electronic components of the disk.

current hard drive- A unique component of the computer. Vіn іkalny tim, scho zberіgaє sluzhbovu іnformatsiyu, vichayuchi yaku, you can estimate the "health" of the disk. This information is to retaliate against the history of changing the impersonal parameters, which are determined by the hard drive in the process of functioning. More than the same component of the system unit, do not give the supervisor the statistics of your work! At the same time, since the HDD is one of the most important components of a computer, such statistics can be even more valuable and help your spymaster to get nervous and spend pennies and an hour.

Information about the mill of the disk is available for a start to the complex of technologies, which are called S.M.A.R.T. (Self-Monitoring, Analisys and Reporting Technology, that is a technology for self-monitoring, analysis and sound). This complex is great, but let's talk about those aspects, which allow you to look at the attributes of S.M.A.R.T.

I will appoint, as I said below, to disks with SATA and PATA interfaces. SAS, SCSI drives and other server drives also have S.M.A.R.T. That monitor server disks sound not like a person, but a RAID controller, we don’t say anything about them.

Also, as I see it, S.M.A.R.T. in any of the numerical programs, then the picture will come approximately (on the screenshot of the S.M.A.R.T. guidance of the Hitachi Deskstar 7К1000.З HDS721010CLA332 disk in HDDScan 3.3):

In the skin row, the ocremic attribute S.M.A.R.T. Attributes can be more or less standardized and named the song number, so that they do not lie in the model of the disk drive.

Skin attribute S.M.A.R.T. May sprat watering. The skin field is brought up to the first class from the next ones: ID, Value, Worst, Threshold and RAW. Let's look at leather from the classes.

• ID(may also be called Number) - identifier, attribute number in S.M.A.R.T. Naming one and the same attribute by programs can be seen in a different way, and the axis identifier will always uniquely designate the attribute. It is especially appropriate for different programs, as they translate the name of the attribute from English into Russian. Sometimes you can enter such a white-beard, so you can understand what the parameter is, you can only use the first identifier.
• Value (Current)- more precisely the value of the attribute in parrots (that is, the values ​​\u200b\u200bof the unknown size). In the process of the Winchester's work, it can change, increase and become permanent. It is impossible to judge the "healthy" attribute by the Value indicator without comparing it with the Threshold values ​​of the same attribute. As a rule, the smaller the Value, the higher the attribute value (in the beginning, all classify the value, RAW, the maximum value may be on the new disk, for example 100).
• Worst- Bigger value, which reached the value of Value for all the life of Winchester. They also win at the "parrots". The process of work may change or become permanent. According to the new one, it is not possible to unequivocally judge the health attribute, it is necessary to improve yoga from Threshold.
• Threshold- the value in the "papugs", which can be reached by the Value of the attribute, so that the attribute becomes critical. Seemingly simpler, Threshold is the threshold: otherwise Value is greater than Threshold - the attribute is in order; yakscho less abo dorіvnyuє - with the attribute of the problem. By itself, for such a criterion of a utility that reads S.M.A.R.T., one sees a call about the camp of a disk or an attribute on the Good or Bad kshtalt. If you don’t care about the stench, what can be done with Value, greater than Threshold, the disk can actually be in the distance from the point of view of the coristuvacha, otherwise it’s a walking bastard, so when assessing the health of the disk, it still marvels at a different class attribute, and itself - RAW. However, the very value of Value, which has fallen below Threshold, can become a legitimate drive for replacing a disk under warranty (for the warranty holders themselves, obviously) - who can say more clearly about the health of the disk, if not myself, demonstrating more precisely the value of the higher attribute for critical threshold? That is, with a value of Value greater than Threshold, the disk itself matters that it is an attribute of health, and with a smaller aborigine - that it is sick. Obviously, with Threshold = 0, the status of the attribute of nothing to evaluate was recognized as critical in no way. Threshold- constant parameter, sewn with a virobnik at the disk.
• RAW (Data)- Naytsіkavіshy, important and necessary for the evaluation of the show. The majority of vipadkiv vіn vengeance is not “fathers”, but real meanings, which are expressed in different loneliness of vimіryuvannya, which can be directly spoken about the in-line mill of the disk. Grounding itself on this show, the value of Value is formed (and for some algorithm it is not formed - it’s already the mystery of the virobnik, covered by confusion). Itself vminnya to read and analyze the RAW field gives the possibility to objectively evaluate the Winchester camp.

Let's take a look at all the attributes of S.M.A.R.T.

Before describing the attributes and valid values ​​of your RAW field, let me clarify what attributes can be the mother of a RAW field. different type: more precisely, that cumulative. More precisely, the field is to replace the value of an attribute at a given moment, for a new authoritative periodical change (for some attributes it is a sign, for others - a lot of times per second; otherwise, on the right, in S.M.A.R.T. reading programs, such a change is not shown). Accumulating a field to collect statistics, call in a new search for a number of milestones of a specific date in the hour of the first disk launch.

The in-line type of attack attributes, but there is no sense to sum up their forward indications. For example, an indication of the temperature of the disk, let's be more precise: yoga meta - demonstrate the temperature at once, but do not sum up all the forward temperatures. An aggravating type of power to the attributes that sway the influence of this information over a long period of "life" of Winchester. For example, an attribute that characterizes the hour of the work of the disk, є accumulative, to avenge a single hour, accumulating for the whole history.

Let's start looking at the attributes of those RAW-fields.

Attribute: 01 Raw Read Error Rate

For all Seagate, Samsung drives (starting from the SpinPoint F1 family (inclusive)) and Fujitsu 2.5″, the characteristic values ​​are in these fields.

For other Samsung drives and all WD drives, each field has a characteristic value of 0.

For Hitachi disks, each field has a characteristic 0 hour periodic field change no more than 0 to a few ones.

So, it is important to note that all hard disks from Seagate, Samsung and Fujitsu do not respect the values ​​of these parameters, like WD, Hitachi and other Samsung. When working, whether it’s a Winchester, such pardons are given, and wines do them independently, it’s normal, just on disks, like in the same field, 0 or a small number, the virobnik did not care for the need to order the correct number of pardons.

Thus, a non-zero parameter on WD and Samsung drives up to SpinPoint F1 (not included) and a large parameter value on Hitachi drives can indicate hardware problems with the drive. It is necessary to be careful that the utilities can display the value of the attribute that can be placed in the RAW field of this attribute, as one thing, and it will look very great, even though it would be wrong (div. below).

On Seagate, Samsung (SpinPoint F1 and newer) and Fujitsu drives, you can not pay attention to any attribute.

Attribute: 02 Throughput Performance

The parameter does not give any information to the coristuvachev and do not talk about any kind of concern for whatever its meaning.

Attribute: 03 Spin-Up Time

The hour of distillation can be adjusted in different discs (and in the discs of one rake also) fallowly in the case of twisting, mass of mills, nominal speed of the spindle, etc.

By the way, Fujitsu winchesters are always loneliness in this field at times of problems with spinning of the spindle.

Practically nothing can be said about the health of the disk;

Attribute: 04 Number of Spin-Up Times (Start/Stop Count)

Assessing your health, do not rely on the attribute of respect.

Attribute: 05 Reallocated Sector Count

It is understandable that such a "reassignment of the sector" took place. If the disk in the robotic process hits a sector that is not readable / read badly / unrecorded / badly recorded, you can infringe it wrongly. Specially for such conditions, the virus is transmitted on the skin disk (on some models - at the center (logical end) of the disk, on some models - for example, on the skin track just) the reserve area. For the presence of a bad sector, the disk indicates it as unreadable and replaced the new sector in the reserve area, adding invalid marks to the special list of defects on the surface of the G-list. Such an operation is called the recognition of a new sector for the role of the old one. remap (remap) or reappointment, and victorious deputy of the poor sector reassign. The new sector will take the logical LBA number of the old one, and now when you return the LP to the sector with this number (the program does not know about the reassignment date!) The request will be redirected to the backup area.

In this order, even if the sector is out of whack, the volume of the disk is not changed. It dawned on me that wines are not changed until the singing hour, so that the reserve area is not unlimited. However, the reserve area can replace thousands of sectors, and assume that it has ended, if it’s even safer, the disk will need to be replaced back to the last one.

Speaking of which, repairers seem to think that Samsung drives often don't want to reassign sectors.

What is the attribute of thought to be divided. I especially respect that even if the wines are 10, the disk needs to be changed - even if it means a progressive process of degradation, I will become on top of either the lenses, or the heads, or the hardware, and the sound of this process is no longer possible. Prior to speech, for honors, approaching Hitachi, Hitachi itself changes the disk with a replacement, which will replace it, if there are already 5 reassigned sectors on it. For more information, what is official information, and what are the opinions of the service center. I can tell you what I don't :)

In addition, the service center's recorders may consider the disk to be invalid, as the company's disk search utility is written to the “S.M.A.R.T. Status: Good” or the value of the Value or Worst attribute will be greater than the Threshold (well, the picker utility itself can be evaluated by such a criterion). І formally stink to make a walkie-talkie. But who needs a disk from the post-improvements of its hardware components, navit as such an impairment to the nature of the hard drive, and the technology of the hard disks to mitigate the damage, seeing, for example, the reserve area?

Attribute: 07 Seek Error Rate

The description of the formation of this attribute may be changed again with the description of the attribute 01 Raw Read Error Rate, due to the fact that for Hitachi hard drives the normal values ​​of the RAW field are only 0.

In this way, do not give respect to the attribute on Seagate, Samsung SpinPoint F1 and new Fujitsu 2.5 ″ drives, on others Samsung models, and also on all WD and Hitachi non-zero values ​​to report problems, for example, with a bearing, etc.

Attribute: 08 Seek Time Performance

Do not give any information to the koristuvachevs and do not talk about any kind of concern for whatever its significance.

Attribute: 09 Power On Hours Count (Power-on Time)

Nothing to say about the health of the disk.

Attribute: 10 (0A - for the sixteenth number system) Spin Retry Count

About the health of the disk, it's best not to talk.

The main reasons for the increase in the parameter є filthy contact of the disk with the PSU or the impossibility of the PSU to see the required strum at the live line of the disk.

Ideally, the reward is 0. If the value of the attribute is 1-2, respect can not be lost. Even more important, in the first turn, turn the attention to the camp of the life block, this way, navigating to the new one, turn over the contact of the hard drive with the life cable, turn over the life cable itself.

Surely, the disc can start up not immediately through problems with itself, but it’s more rare, and it’s necessary to look at it in the rest of the day.

Attribute: 11 (0B) Calibration Retry Count (Recalibration Retries)

A non-zero, especially large value of the parameter may indicate problems with the disk.

Attribute: 12 (0C) Power Cycle Count

Do not po'yazany іz the camp of the disk.

Attribute: 183 (B7) SATA Downshift Error Count

Do not say about healthy'ya nakopichuvacha.

Attribute: 184 (B8)

A non-zero value indicates disk problems.

Attribute: 187 (BB) Reported Uncorrected Sector Count (UNC Error)

A non-zero value of the attribute explicitly indicates an abnormal disk state (for a new non-zero attribute value of 197) or those that were so earlier (for a new zero value of 197).

Attribute: 188 (BC) Command Timeout

Such pardons can be blamed on the bad quality of cables, contacts, wired adapters, jacks, etc., as well as through the inconsistency of a disk with a specific SATA / PATA controller on the motherboard (or discrete). Through pardons of this kind, you can BSOD in Windows.

The non-zero value of the attribute is to talk about the potential "illness" of the disk.

Attribute: 189 (BD) High Fly Writes

In order to say why such behaviors occur, it is necessary to analyze the S.M.A.R.T. logs, in order to find information specific to the skin verifier, which is not implemented in the publicly available software security today, you can’t do that attribute.

Attribute: 190 (BE) Airflow Temperature

Do not say about the camp of the disk.

Attribute: 191 (BF) G-Sensor Shock Count (Mechanical Shock)

Relevant for mobile hard drives. on the Samsung drives you can often not pay attention to something, because the stench can be a very sensitive sensor, which, figuratively, apparently, reacts not to the wind when the wings are flying in the same place with the disk of a fly.

Vzagalі, spratsovuvannya sensor is not a sign of impact. It is possible to increase the position of the BMG with the disk itself, so you can’t fix it. The main function of the sensor is to initiate an operation to record the first hour of vibration, in order to cancel pardons.

Do not say about the health of the disk.

Attribute: 192 (C0) Power Off Retract Count (Emergency Retry Count)

Do not allow budding about the camp of the disk.

Attribute: 193 (C1) Load/Unload Cycle Count

Do not say about the health of the disk.

Attribute: 194 (C2) Temperature (HDA Temperature, HDD Temperature)

Do not talk about the attribute of the disk, but it allows you to control one of the most important parameters. My thought: for an hour of work, try not to allow the temperature of the hard drive to rise above 50 degrees, even if the vibrator sounds and declares the maximum temperature between 55-60 degrees.

Attribute: 195 (C3) Hardware ECC Recovered

Features, the power of the attribute of different discs, are more likely to be attributed to such attributes 01 and 07.

Attribute: 196 (С4) Reallocated Event Count

Pobіchno to talk about the health of the disk. The more important - the more important. However, it is impossible to unequivocally judge the health of the disk by this parameter without looking at other attributes.

This attribute directly overlaps with attribute 05. With growth 196, the most frequent growth is i 05. As well as with attribute 196 growing, attribute 05 does not grow, which means that when trying to remap, the candidate for the bad block turned out to be a soft-bad (detailed div. below), and having corrected yoga, the sector of recognition is healthy, and there was no need for reassignment.

As attribute 196 is smaller than attribute 05, it means that for the first hour of the reassignment operations, the transfer of several weak sectors was transferred in one go.

As attribute 196 is larger than attribute 05, it means that during certain operations the reassignment was revealed by the soft-bed.

Attribute: 197 (С5) Current Pending Sector Count

If the process encounters a “bad” sector (for example, the checksum of the sector is not found in the new one), the disk designates it as a candidate for reassignment, add it to a special internal list and increase parameter 197. Poshkodzhenі sectors, about yakі vіn still don't know - even on the plates as a whole can be oblasts, like Winchester this hour is not victorious.

When trying to write to a sector, the disk is rechecked, which sector is in the list of candidates. If the sector is not found there, the entry is taken in the highest order. It has been found that the sector is being tested by writing-reading. If all test operations pass normally, make sure the disk is in the reference sector. (T. e. letter so-called “soft-bed” - the pardon sector of the vinyl is not the fault of the disk, but of other reasons: for example, at the time of recording the information, the electricity turned on, and the disk interrupted the recording, parked the BMG. As a result, data in sectors will be underwritten, and the control amount of the sector, which should be deposited with data from the new one, will become redundant with the old one.

As the test ends in failure, the disk fails the reassignment operation, changing the attribute 197, increasing 196 and 05, and also rob the icons in the G-list.

Again, a non-zero value of the parameter can speak of problems (although you can’t say about those with a problem on the disk).

With a non-zero value, it is necessary to run the language in Victoria programs or MHDD after reading all surfaces as an option remap. Then, when scanning the disk, swipe it around the bad sector and try to record it to a new one (Victoria 3.5 has this option). advanced remap— the disk can be rewritten to record a sector up to 10 times). In this way, the program provokes the “likuvannya” of the sector, and as a result, the sector will either be corrected or reassigned.

In times of failure, reading like s remap, so i h advanced remap varto try to run the last record in the same Victoria or MHDD. Insure that the operation of the record erases the data, before the її zastosuvannyam obov'yazkovo robіt backup!

In some cases, the remap can be supplemented by the following manipulations: remove the electronics board of the disk and clean the contacts of the HDA of the hard drive to connect it with the board - stench can be oxidized. Be careful when vikonannі tsієї procedures - through it you can spend a guarantee!

The impossibility of remapping may be due to one more reason - the disk has exhausted the reserve area, and you simply cannot reassign sectors.

Even though the value of attribute 197 is not reduced to 0 by any manipulation, you should think about replacing the disk.

Attribute: 198 (C6) Offline Uncorrectable Sector Count (Uncorrectable Sector Count)

This parameter is changed only in the offline test, no scanning programs on the new one. During operations pіd hour self-testing behavior of the attribute is the same as the attribute 197.

It's non-zero meaning to talk about problems on the disk (so, like і 197, without specifying who is to blame).

Attribute: 199 (C7) UltraDMA CRC Error Count

The most important reasons for the pardons are an inaccurate transmission loop, the expansion of the PCI / PCI-E busses of the computer, and the bad contact of the SATA-pins on the disk of the motherboard / controller.

Pardons during transmission over the interface i, as a result, an increasing value of the attribute can cause the operating system to switch to the robotic channel mode, on which the storage device is located, the PIO mode, which causes a sharp drop in the read/write speed when working with it and the processor is busy. % (seen in Windows Job Manager).

In the case of Hitachi hard drives of the Deskstar 7K3000 and 5K3000 series, the growth attribute can be said about the insanity of the disk and the SATA controller. To correct the situation, it is necessary to switch the disk in SATA 3 Gb / s mode.

My thought: for obvious pardons - reconnect the cable from both ends; for example, if your number grows and won more for 10 - leave a train and put a replacement for a new one, or take a rozgin.

Attribute: 200 (C8) Write Error Rate (MultiZone Error Rate)

Attribute: 202 (CA) Data Address Mark Error

Attribute: 203 (CB) Run Out Cancel

Probably a description of the attributes. Non-zero values:

When analyzing attributes, ensure that the S.M.A.R.T. you can save the value of the value of the parameter: for example, before the start of the disk and the rest. Such parameters with a maximum number of bytes are logically added up with a maximum value of a minimum number of bytes - for example, a parameter that takes two values ​​​​for the two remaining launches, for which 2 bytes are entered, for example, a maximum of 4 bytes. Programs that interpret S.M.A.R.T. often do not know about it, and show this parameter as one number, not two, which can sometimes lead to swindling and praising the disk manager. For example, "Raw Read Error Rate" which takes the value "1" beforehand and the remaining value "0" would look like 65536.

Please note that not all programs can display these attributes correctly. It is rich to translate the attribute with kіlkom values ​​into the ten system of numbers as one great number. Well, it’s right to choose such a place - either with a difference for the values ​​​​(then the attribute is composed of a number of numbers), or in the sixteenth system of numbers (then the attribute looks like one number, but the other warehouses will be easily remembered at first glance), or else, that otherwise at once. The butts of the correct programs are HDDScan, CrystalDiskInfo, Hard Disk Sentinel.

Demonstration of visibility is practical. The axis looks like this at attribute value 01 on one of my Hitachi HDS721010CLA332, especially Victoria 4.46b attribute value, which is not correct:

And this is how the faults of the “correct” HDDScan 3.3 look like:

The advantages of HDDScan in this context are obvious, aren't they?

How to analyze S.M.A.R.T. on different disks, you can note that some of the attributes themselves can behave differently. For example, deakі parameters S.M.A.R.T. Hitachi hard drives are reset after a single period of disk inactivity; parameter 01 may be special on Hitachi, Seagate, Samsung and Fujitsu drives, 03 - on Fujitsu. Also, after flashing the disk, the parameters can be reset to 0 (for example, 199). However, similarly to the primus attribute resetting to zero at any time, we do not talk about those that had problems with the disk (which they did). Aje growing critical attribute - tse consequence trouble, not cause.

When analyzing multiple arrays of S.M.A.R.T. It becomes obvious that the collection of attributes from the disks of different selections and the creation of different models of one selection can be modified. It is tied to the so-called vendor-specific attributes (those attributes that are used for monitoring their disks by a singer-songwriter) and are not guilty of being a drive for praise. If it is possible for software monitoring to read such attributes (for example, Victoria 4.46b), then on disks for which stench is not recognized, stench can have a “terrible” (magnificent) meaning, and they simply do not need to be protected. So, for example, Victoria 4.46b displays RAW-values ​​of attributes that are not recognized for monitoring Hitachi HDS721010CLA332:

The problem often arises when the programs cannot implement S.M.A.R.T. disk. For a different hard drive, it can be caused by kilkom factors. For example, S.M.A.R.T. when the disk is connected to AHCI mode. In such cases, you can try various programs, the HDD Scan zocrema, so you can work in this mode, even though it doesn’t have to go out, or you can switch the disk to the IDE mode at times, so it’s such a possibility. Dali, on bags motherboards controllers, to which hard drives are connected, are not included in the chipset or pivdenny city, And implemented by other microcircuits. In this case, the DOS-version of Victoria, for example, does not allow connections to the hard disk controller, and it will be necessary to start it by pressing [P] and entering the number of the channel with the disk. Often not read S.M.A.R.T. for USB drives, as explained by this, the USB controller simply does not pass commands for reading S.M.A.R.T. Maizhe never read S.M.A.R.T. disks that function at the warehouse RAID array. Here it is also a good idea to try out different programs, but it's safer for hardware RAID controllers.

After the purchase and installation of a new hard drive, be it programs (HDD Life, Hard Drive Inspector and others) show that: the disk has lost its life for 2 years; yoga productivity - 27%; health - 19.155% (select to your liking) - do not panic. Think like this. First, it is necessary to marvel at the S.M.A.R.T. shows, and not at the numbers of health and productivity, which the stars came from inadvertently (in this case, the principle of their foolish intelligence: take the biggest show). In another way, be it a program in terms of S.M.A.R.T. marvel at the significance of various attributes of the front indications. At the first launch of a new disk, the parameters are not stable, it takes one hour to stabilize it. The program that evaluates S.M.A.R.T., succumb, that the attributes are changing, robbing the cracks, it comes out, that when you change it at such a pace, it will soon get out of tune, and it starts to signal: “Rate the tribute!” One hour has passed (until a few months), the attributes are stabilized (everything is true with the disk), the utility collects data for statistics, and terms of disk death in the world of stabilization S.M.A.R.T. endure all the distance and distance in the future. The assessment by the programs of Seagate and Samsung disks is like a rose. Through the features of attributes 1, 7, 195, the programs for an absolutely healthy disk will sound to see the whiskers, which the wines lit up in the air and took to the zvintar.

Be aware that the situation is possible: all the attributes of S.M.A.R.T. - in the norm, the prote is true disk - with problems, although it is still not noticeable. We explain that the S.M.A.R.T. Pratsyuє only “behind the fact”, so that the attributes are changed only once, if the disk of the robotic process has a problematic area. And if you don’t drink wine docks on them, then you don’t know about them and, after all, S.M.A.R.T. youmu fix a lot of things.

In this rank, S.M.A.R.T. - This is the core of technology, but it is necessary to use it with reason. In addition, navit as S.M.A.R.T. the disc is ideal, and you are constantly in charge of the verification disc - do not rely on those that your disc will "live" for a long time. The Winchesters are so powerfully lamatized that S.M.A.R.T. you just don’t get the idea of ​​​​yogo camp, which is changing, but it’s like that, what’s with the disk - it’s obviously nonsense, but in S.M.A.R.T. - all right. You can boldly say that a good S.M.A.R.T. I do not guarantee that everything is good, but the S.M.A.R.T. guaranteed to report about problems. With whom to navit іz filthy S.M.A.R.T. utilities can show that the state of the disk is “healthy”, through those that critical attributes do not reach the boundary values. It is important for him to analyze S.M.A.R.T. yourself, relying on the "verbal" assessment of the programs.

Wanting S.M.A.R.T. and pracyuє, vіnchestery that understanding “nadіynіst” nastіlki nesumisnі, scho adopted vvazhat їх simply window material. Well, like printer cartridges. To that, in order to escape wasting valuable data, to make periodic backup copies on another nose (for example, another hard drive). Optimally work two backup copies on two different noses, winchester cream with original tributes. So, vede to dodatkovykh vitrats, ale povirte: vitrati on updated information from HDD, scho zlamavsya, will cost you at once - even if not an order of magnitude or another - more expensive. But data is far from being able to inspire professionals. That is the only way to ensure the safety of your data - to protect your backup.

Nasamkinets I will guess some programs that are good for the analysis of S.M.A.R.T. and testing hard drives: HDDScan (Windows, DOS, cost-free), MHDD (DOS, cost-free).
