aass, didn't use it. But I note that Victoria and MHDD are proven tools for serious diagnostics.

And Windows 7 can track SMART information. It will warn you if anything happens.

aass

Vadim Sterkin, Thanks for the answer and for the topic!
I agree with the assessment of the Victoria and MHDD programs, I myself use Victoria for serious diagnostics, but I try to test other programs, everything is learned by comparison.)

Dmitriy

When checking the hard drive with a standard program on Windows 7, it says that bad clusters were detected in null.sys... what kind of driver is this?

Dmitriy

Vadim Sterkin,

thanks...can the system slow down because of it?

Sanyok

Hello.
I ran (hypothetically) checking the C: drive from the graphical interface with parameters similar to your screenshot. Clicked the "Schedule disk check" button. Changed my mind. How can I cancel this one-time system disk check before rebooting the system?
I myself assume that it may be entered into the Task Scheduler.” But I want to know for sure. I see no point in experimenting. Since, after such a check was completed successfully once (in practical reality), it would be entered into the “Scheduler” even as a one-time check, and should, in theory, be saved. After all, tasks from the “Scheduler” do not have the ability to self-delete (I think so). But I didn’t find any traces in the “Planner”. As you probably know, I didn’t receive an answer on the Internet or on the forum.

Simply put, I want to know where this mythical “Check Schedule” is located and what methods and methods Windows 7 offers for adjusting it. And then it turns out like this - click, and ala-ulu...

Sanyok

Yeah…
There were graphics, but they all came out. This is some kind of graffiti, black and white, with a register. Just like Battleship Potemkin.
(Yes, I Googled, but really for a slightly different request). Thank you.
You can plan this by checking two boxes in the chart, and canceling by going to the register. They got smart here. Well, okay, there’s nothing to do - I’ll post in the forum.

Yes, by the way, does it make sense to check the second (bottom) checkbox if the system is on an SSD? After all, as far as my knowledge is sufficient, the SSD controller itself periodically (when idle) scans the memory for faulty cells.
And this second checkbox, by definition, is intended to check for broken cells on the surface of the HDD.

Sanyok

Sanyok,

You turn on your TV with the remote control and set the wake-up timer. The next morning you wake up to the music of your favorite music channel. And life flows smoothly and measuredly. But at one fine moment it dawns on you - after all, tomorrow is Sunday. No problem, you tell yourself. With a slight movement of your hand and a screwdriver, without unplugging the TV from the mains, you remove the back cover, quickly replace a couple of resistors on the board and you’re done. Tomorrow you can sleep peacefully until lunchtime.
Do you feel what I mean?

Vadim Sterkin: Sanya, what do you mean, smart? You don’t have to split hairs by pressing all sorts of strange buttons, and everything will be fine :)

It's really funny, but also of course, of course Truth.
Yes, but it’s not quite out of place. I don’t see anything unpredictable or completely incomprehensible in checking the disk. And the conversation was about the fact that if you have already provided a graphical opportunity to schedule such a task, then be kind enough to provide the same opportunity to disable it, and not through one place (the registry). Either remove graphics when planning (do planning only through CMD), or provide the ability to disable this task using the graphical interface. As an engineer, in my technical practice and in the practice of interfaces of various industrial programs and IT, this is the first time I have come across something like this. Yes, and in Windows OS too.
That’s what I wanted to convey when I said, “We’ve been clever.”
When faced with a question, I noticed that this function causes complaints from the user in terms of frequent independent launches. But let's not talk about that. As unrelated to the topic.
And of course, thanks for the comments. Everything is clear to me here.

Regarding the bottom daw:

To perform a thorough disk scan, select the Scan and repair bad sectors option. In this mode, the scanning program attempts to find and correct physical errors on the hard drive itself, which may take much longer.

It doesn't say anything about the file system. More about physical disabilities. Some of us are wrong. Or I didn't understand something.
And further in the text:

To check for both file and physical errors, select both options: Automatically fix system errors and Scan for and repair bad sectors.

Please comment. I would like clarity on the issue.
So as not to press “all sorts of strange buttons”, and everything was fine. :-)

I am very surprised by the capabilities of checking and restoring a disk under Windows 8. Changing the partition size upward using Acronis Disk Director 11 ended with errors. I wanted to increase the size of the system disk using the empty space on the adjacent partition by 200 GB. As a result, this program reports that everything is OK, and the disk size in Explorer has not changed. I checked the disk using the OS - it said that there were errors and needed to be rebooted. After the reboot, nothing changed and a request appeared to reboot to fix it. As you can already guess, this also did not help. As a result, we have lost 200 GB, despite the fact that Acronis says everything is ok, but the system is not able to correct the errors found. Sadness. Do I need to format it?

Vyacheslav

Vadim Sterkin,

In fact, under Windows 7, a similar operation was always performed without problems. I always perform the task of expanding/narrowing a partition in 2 stages: first, we cut off a piece of space from the partition being compressed and transfer it to the “unallocated space” status from the required end of the partition, and then we expand another partition using this space (I do everything manually in 2 reboots in case of “jambs”, because Acronis performs a group of operations very strangely. There is a sad experience under Windows XP). So, if under Windows 7, after checking the disk, everything returned to normal and the free space did not disappear so easily, then under Windows 8 Acronis completed the first stage successfully, and when performing the second it broke down with errors, although then it reports that “everything is fine.” The problem was eventually resolved by booting from a Live CD from Acronis. It's a pity that this cannot be done under Windows 8. And I was counting so much on the “improved checking and correction of file system errors” promoted in the media. Of course, it is very difficult to trust that checking and background diagnostics of FS problems is working correctly. It is very confusing that the time to scan one partition under Windows 7 and under Windows 8 differs by orders of magnitude, for the better for the latter. Are all problems really so easily and quickly fixed? Maybe Windows 8 simply doesn’t notice most of them, or even worse, ignores them?

Vyacheslav

Vadim Sterkin,

Well, what option is there in Windows 8 to expand the partition size? I saw the Disk Management snap-in. Well, I didn’t see how it’s possible to cut the size of a logical volume from the desired end using “standard means”. There's also no way to move a partition within the unallocated space. If there is an analogue that I missed, tell me. Along the way, you did not quite correctly understand what I meant by the phrase “I had a bad experience under Windows XP.” And it was like this: after a reboot, this operation was performed and at that moment the electricity went out. Thus, I lost 2 partitions, although, in theory, there could have been 3 options: the second partition would have been lost, from which space was taken due to the incompleteness of the operation of moving NTFS service zones, or only the system partition would have been lost (although this is unlikely), or both partitions would be fine, and between them there would be some area of ​​unmarked space. But I was very “lucky”. Let’s skip the topic of uninterruptible power supplies and it turns out that Acronis is a reputable company, and their products are sometimes dangerous to use in any way in the absence of alternatives from the OS. And then another “surprise” emerged. And even here everything is in order with the power supply. But as I already noted, the last problem was solved by booting from a Live CD from Acronis and a classic disk check, and not the over-optimized one from Windows 8, the benefits of which I have not yet felt. It seems to be there, but there seems to be no point. Or maybe I was using the disk check tool wrong. Unfortunately, this “optimization” still raises more questions and mistrust in me than answers.

Vyacheslav

Vadim Sterkin,

Irina

Conducted Windows hard drive diagnostics (chkdsk). There were no messages, but later it turned out that there was no free space. Although before the check, less than 50% of the disk was full. And now it shows 931 GB occupied. Was all the free space wasted? The disc is six months old.

I forgot to say, after that I checked with Victoria and reported that there weren’t even any errors.

Irina

This is not the case for me. We are not talking about the system disk. And about the external drive. I’ve already found out that the system marked all the free space as bad blocks. Now I’m trying to figure out whether it’s a failure or whether the screw has died.

Sergey

Vadim, I have the following problem: After running the chkdsk disk check utility, if both “daws” are checked, it asks to reboot and the check is performed, I don’t know what to call it, but it looks like MS-DOS - lines run quickly on a black background. After the next reboot, I look at the information in the Windows Logs - Application, text in English, “there are many letters,” but the meaning can be understood from a single sentence: “Windows has checked the file system and found no problems.” At the same time, a few lines above I was kindly informed that, they say, “Cleaning up 31 unused security descriptors.” Sometimes it is not “31 unused security descriptors” that are cleared, but more or, conversely, less. That is, something is still not quite right, and the program corrects it a little. Like, overall everything is fine, but the Bug died. So, no matter how many times I run this chkdsk, it requires a reboot to correct these errors, nothing else is detected. Previously, on another machine in Windows XP this happened rarely, but now it happens time after time.
The SSD drive is about a quarter occupied. The system is legal Windows 7 x64 Professional and is automatically updated. If you don’t run disk check, then there is no reason to worry, everything works fine, doesn’t glitch or crash. So, in connection with this, the question is - maybe there is no need to spoil your mood. I didn’t find a solution to the problem of these file system errors on the Microsoft website, and are they really errors?

far_town2 Kulyasov

Are there any methods to check if the power supply is sufficient? And due to its insufficient power, can freezes/errors occur in games?

Most personal computers and even servers use hard drives to store information. They are quite reliable, but over time, magnetic drives become unusable. In most cases, the service life of the disk is 5-10 years. Each user must be able to diagnose the HDD in order to determine the need to replace the part and perform a data backup. You will learn everything about verification from this article.

Symptoms of hard drive problems

Malfunctions or imminent death of the hard drive may be accompanied by typical symptoms. We recommend paying attention to the following symptoms:

• The appearance of uncharacteristic sounds during operation. There may be clicks, crackles, or metallic clanging. In such cases, the problem is usually mechanical in nature.
• “Brakes” in the operation of the system. Windows loads too slowly, some files do not open, and errors occur when installing programs.
• The appearance of blue “screens of death”. In such cases, an error code is always written, which can be used to determine the source of the problem.
• Spontaneous shutdown or reboot of the computer. As a rule, in such situations, the boot sector of the HDD is damaged.

Please note that computer freezes can also occur due to insufficient RAM.

Ways to check the hard drive

HDD diagnostics is an important task. There are several ways to do this. Operating system tools allow you to analyze your hard drive, but they are not always effective. The optimal solution is to use specialized utilities that are created specifically for this task.

Via command line

Windows operating systems have a standard utility that can analyze the status of the hard drive. To do this you will have to run the command line:

In the command parameters, specify the drive letter and two specifiers. The first - F is responsible for automatic error correction, and R performs information recovery. Be prepared that the verification may take several hours. If you are using a laptop, be sure to charge it. At the end you will get statistics on how many sectors are damaged.

Using Windows Explorer

If you prefer using familiar windows, you can run the scan through Explorer. To do this, users should follow a number of steps:

During this operation, the system will perform the following checks:

• basic file system structure;
• security descriptors;
• file name associations;
• USN magazine.

To find out the scan results, you need to go to the “Event Viewer” menu, and then find the scan log in the Windows log.

Via Windows PowerShell

The latest Windows operating systems have an additional utility similar to the command line, which was created for convenient system administration. You can also use it to test your hard drive. To start, you need to perform several steps:

The system will scan and automatically fix if possible. If there are no errors, the message NoErrorsFound will appear.

Using Windows 10 Tools

The latest operating system from Microsoft has advanced functionality, so it can independently diagnose a wide range of problems. Using the built-in security center, you can check the status of the HDD. Additionally, go to storage diagnostics. How to use these functions will be described below.

Security and Service Center

This is a special section in the “ten”, which is responsible for maintaining the operating system. As a rule, all necessary checks are performed automatically after a certain period of time. You can access this section through the control panel. Next, if necessary, open the “Maintenance” tab and find the “Disk Status” line. Opposite it should be the “OK” option. If it is not there, then we recommend conducting a thorough analysis of the condition of the hard drive.

Storage Diagnostic Utility

The developers of Windows 10 also created an additional utility for checking the hard drive - storage diagnostics. It is launched via the command line (how to open it was described in the sections earlier). Next, enter the command and press Enter.

The procedure may take 2-5 hours (depending on the HDD capacity). At some points the process will appear to be stuck, but it is strongly recommended that you do not interrupt the scan. Once the process is complete, navigate to the path to save the report and open it (the file will have evtx permission). It will provide the following information:

• chkdsk check data and error information;
• registry files containing data about connected drives;
• Event Viewer Logs.

Experienced specialists are required to correctly interpret the information presented in the report. The report will be uninformative for ordinary users.

Third party programs

For professionals and ordinary users, third-party developers have created many useful, functional and easy-to-use utilities for checking the status of the hard drive. With their help, you can get comprehensive information about the status of your HDD. The most popular of them will be described below.

Victoria

This is the most popular free software from qualified specialists. Its wide functionality allows you to get almost any information about the hard drive. The parameters are displayed in a form convenient for the average user, so you don’t have to study anything additional to make a conclusion about the state of the HDD. The utility is distributed on a Freeware basis, i.e. absolutely free.

Download the software to your computer and follow the instructions:

All sectors will be marked in different colors depending on the response speed. Gray sectors are not dangerous. Green sectors are allowed in quantities of several hundred (up to 2-3 thousand). For example, on a completely new 1TV hard drive their number is about 1 thousand. Orange sectors are at their limit. No more than 100 pieces are allowed. Red and blue cannot be restored. They need to be “closed”, limiting reading from them.

When scanning, you can set the operating modes:

• Ignore is a classic check without further action.
• Remap – replacing unreadable sectors with reserves if available.
• Restore – restore damaged sectors programmatically.
• Erase – overwriting unreadable sectors. Attention, erases information.

As you can see, the utility is informative and easy to use even for beginners.

HDDScan

Another useful software for scanning your hard drive. It has less functionality, but a more friendly interface compared to the previous version. The utility is completely free, and allows you to get SMART parameters and detailed information about the state of sectors.

To start the verification procedure, follow these steps:

The colors for the sectors are identical to those described above. The scanning menu does not provide functions for correcting sectors.

DiskCheckup

The software supports work with almost all types of hard drives (SATA, USB, FireWire). It has small but sufficient functionality. Through the application, you can check the SMART parameters, as well as conduct a full test on the Disk Self-Test tab. The main disadvantage of the program is the complexity of the results for the average user. The status is indicated by the “OK” line and numerical parameters. Considering that they are all in English, it will be difficult to understand.

MHDD

This is highly specialized software for advanced users. It is used if the system does not start and the OS does not load to the desktop. To run MHDD software, you must burn it to a CD or flash drive as an image. You can even run the utility with the entire operating system. To do this, you need to select a flash drive or CD as the boot drive when using a floppy drive.

After the menu appears, you just need to select the desired hard drive and enter the command to check. The software is controlled in the same way through commands as on the console, or using the function buttons of the keyboard. Not recommended for use by ordinary users without appropriate skills.

Crystal Disk Mark

This utility allows you to evaluate the speed of writing and reading information from your hard drive. In its interface, the user can select the write/read type, local disk and file size to be read and written. After finishing the test you will receive information at speed.

You will not be able to evaluate these results yourself. We recommend finding a similar HDD model online to compare its testing with your test data. If the results with identical settings are almost the same, then there is no need to worry. If there are strong differences, we recommend analyzing the hard drive through Victoria.

HDD Regenerator

Functional utility for HDD scanning and recovery. A special magnetization reversal algorithm allows you to eliminate quite serious problems with the hard drive. To launch the software you should:

The advantage of this utility is the ability to quickly correct errors and close bad sectors.

Seagate SeaTools

Specialized software from Seagate product developers. Allows you to obtain basic information about the disk, perform preliminary and full scans. We recommend using this utility in cases where the above for some reason does not work, and you own a hard drive from Seagate.

Western Digital Data Lifeguard Diagnostic

Special software in English for checking Western Digital disks. It is more suitable for advanced users, but ordinary users can also perform quick diagnostics. For example, you can check the status of SMART parameters.

The utility also allows you to conduct simple and advanced tests, but the information content of the results for typical users leaves much to be desired.

Disk Utility on macOS

MacOS users also have a standard hard drive utility. Its functionality includes:

• creating and transforming images;
• mounting and unmounting disks and other media.
• activation and deactivation of logging mode;
• HDD integrity testing and file recovery;
• erasing, formatting and partitioning disks;
• cleaning up debris;
• adding a partition table;
• checking the S.M.A.R.T status of the hard drive and much more.

To start, you need to find the application in the utilities on the system disk, and then launch it.

Prevention measures

To maximize the life of a hard drive, users can do a variety of things, including:

• Defragmentation. This procedure arranges all file blocks in order, making access to them as fast as possible, accordingly, the head travels less distance to open the file and wears out more slowly.
• Install a quality power supply. Power surges have a detrimental effect on any equipment. If important data is stored on the HDD, take care of a high-quality power supply to prevent damage to the hard drive due to power surges.
• Avoid vibrations and shocks. Winchesters are extremely vulnerable to impacts. When transporting your computer, make sure that the hard drive will not be subject to vibration.
• Clean the system. Freezes due to unstable software or viruses can cause increased load on the disk; accordingly, it will use its resource faster.
• Eliminate external magnetic fields. Many people install the system unit with other powerful equipment that has a magnetic field. If you want to ensure maximum data safety, do not place the system unit next to equipment that emits a powerful magnetic field.

Never forget to make backups. Any hard drive will eventually become unusable, and it is not always possible to recover data. Regular checks will allow you to determine the future demise of the HDD in advance and take action, for example, purchasing a new one.

Often, users encounter situations when Windows starts to work incorrectly.
Loads slowly and displays strange messages. Slowly responds to actions. Files suddenly disappear.
All this may be a consequence of errors in the disk file system and physical damage to the surface, the appearance of poorly readable and bad sector blocks. Bad (unreadable) blocks are also called Bad blocks.
To eliminate such manifestations, you need to check the disks for errors.
In the arsenal of Microsoft Windows maintenance tools there is a Check disk utility, designed specifically for checking and eliminating errors on disks.
Sometimes the Windows system, when it detects problems on any disk or when connecting a new disk (for example, a flash drive), itself launches Check Disk when loading.
Some ignorant users get scared when they see a blue screen with the Check Disk disk checking utility running.
Some people confuse Check Disk startup with the BSOD blue screen of death.
If Check Disk starts, you need to let it run unless you want it to start every time you boot Windows.
If you want to check the disks, first of all you need to check the system disk, usually drive “C”, but not necessarily.
To check the system disk, the error correction utility cannot be run under the Windows operating system. You can only assign a task to check the disk, which will be executed the next time you boot in DOS mode.
If error correction is not specified during the scan, the system disk will be scanned, and the results can be viewed by going to Control Panel>Administration>Event Viewer>Application.
The remaining disks can be checked with the Windows operating system loaded.
There are several ways to set up a scan or run Check disk.

The first method (regular, with a graphical interface):

* Double-click with the left mouse button to open “My Computer”;
* Right-click on the icon of the disk being checked and select “Properties” from the drop-down menu;
* In the “Properties” window, select the “Service” tab and left-click “Run check”;
* In the "Check Disk..." window, check the boxes. If you don’t need to check and repair damaged sectors, naturally don’t check the box. The option to scan and repair bad sectors significantly slows down the scanning process, especially on large-capacity disks. However, the option is useful and necessary for hard drives with a long service life;
* If the disk is a system disk, a task will be created to check the disk at the next reboot, about which a corresponding warning window will be displayed;
* If the disk is not a system disk, the disk will be checked;
After checking the system disk in DOS mode, a report is displayed.
If errors are found, entries will be added about them and their correction. Sometimes there are quite a lot of entries. This indicates that the condition of your disk is not good (I recommend copying the data you need to another medium to avoid losing it).
Perhaps, as system specialists say, it has “started to crumble,” and a more thorough check needs to be done using special programs.

Second method (in DOS mode):

* Press the start button and select “Run” from the menu (see note at the end of the article);
* In the window, type the command chkdsk c: /f, in which: chkdsk is the command to launch the Check Disk utility, c: is the disk to be checked (if you need to check another disk, for example “D”, then set d:, /f is the parameter specifying error correction;
* After typing the command chkdsk c: /f, press the Enter key;
* If the disk is a system one and the f parameter is applied, then, as with the first method, we receive a message about the impossibility of checking and a proposal to set a check at the next reboot, to which we respond by entering Y and pressing the Enter key if we agree with the proposal. The black DOS window disappears, the job is created.
* If the disk is not a system disk, a disk check is performed and the black DOS window disappears.

Third method (in command line mode):

* Press the start button and select “Run” from the menu;
* Type the cmd command, press Enter, a DOS window opens;
* Type the command chkdsk c: (where c: is the disk being checked) and press Enter. The disk is scanned and scan results are displayed.
* To close the window, type exit and press Enter.
If you add the /f parameter to the chkdsk command, as in the previous method, you will receive a warning about the impossibility of checking and a suggestion to set the check the next time you boot Windows.
List of Check Disk utility parameters:
* /f – Enables disk error correction.
* /v – Shows the names of scanned folders and files
* /r – Finds damaged sectors and, if readable, restores the data written to them.
* /x – Can only be used with the NTFS file system. At the beginning of work, the volume is disconnected. The /x option enables the functionality of the /f option.
* /i – Can only be used with the NTFS file system. Checks indexes less thoroughly, which reduces time.
* /c – Can only be used with the NTFS file system. Ignores the folder loop check in the chkdsk command, which reduces check time.
* /l[:size] - Can only be used with the NTFS file system. Specifies the log size.
*/? – Displays help for the utility.
Many experts do not recommend using the Check Disk utility too often due to the risk of damaging the system and data. Frequent checks, in general, are not necessary. Once every six months and in case of problems will be quite enough.
Note: In Vista and Windows 7 operating systems, there is no Run command in the Start menu by default. To make it appear you need to do the following:
* Right-click on the “Start” button on your desktop and select “Properties” from the list.
* In the window that opens, on the Start Menu tab, click “Customize”.
* In the list of the next window, find the “Run” command and check the box.
* Click “OK” to close the windows.

All modern homes have a desktop computer or laptop. Some people need it for games, others for work or study. In any case, photographs, some important records, contact details of people, necessary addresses, etc. are stored on the computer. And the place where all this information is stored is a hard drive.

It is not without reason that experienced programmers say that in a situation where a computer has a hard drive error, formatting it is a real disaster. After all, formatting is fraught with the loss of all information. But this is the case if appropriate measures are not taken. But if you notice some errors and malfunctions in the disk in time and correct them, then you can avoid this global catastrophe

The main causes of HDD problems are “bad” sectors – sections of disk space that are somehow damaged.

They are divided into physical and logical. The latter appear due to software errors and can be corrected, while physical ones cannot be corrected. In the latter case, you will have to replace the hard drive.

Such damaged areas can appear on both magnetic and standard SSD drives.

Causes of bad sectors and errors

Hard drive failures depend on the type of damaged areas:

1. brain teaser“broken” - displayed when there is malware or viruses, as well as when there is a sudden loss of power or power cable during recording;
2. physical“broken” - found on a completely new product. Then you need to contact the manufacturer with a request to replace the product.

In magnetic drives, “broken” sectors can appear as a result of wear of the moving parts of the device, when foreign bodies get into the disk mechanism, or from a simple fall on the floor. In the latter case, the magnetic head of the disk is scratched, which leads to errors.

SSD drives give errors because they have tried to write any information to them many times.

It is quite possible to check the hard drive for “broken” sectors. Windows has an application called "chkdsk" (check disks). You need to open the folder on your desktop or in the Start menu "My computer" by clicking on the drive to be scanned. Using the context menu, select “Properties” - “Service”. Under the phrase “Check” there will be a button, by clicking on which you will be able to see the number of “broken” sectors.

During the test, the computer will eliminate errors in logical “broken” sectors, as well as mark areas with physical damage.

Attention! You can run the scan system manually, but if Windows independently detects “bad” sectors, the utility will launch itself when the system starts.

Checking utilities

Some software does not have built-in verification. For such cases, there are special programs that help identify “broken” sectors and errors and, if possible, correct them.

"Victoria"

It is a popular software for searching damaged areas. In addition to various methods of analyzing and reassigning problem areas, it has a function for searching for damaged contacts in a cable, as well as a function for assessing the performance of the hard drive. The only “disadvantage” of the program is the lack of official assemblies. Therefore, experts recommend using it separately from the OS.

"HDD Regenerator"

This utility uses its own methods to restore “bad” sectors (a combination of high and low signals) and supports any drive connection interfaces.

The downside is the high cost of the license ($90).

One of the best and multifunctional utilities for checking a device for damaged areas. Has the following functionality:

• restores and reconfigures sectors;
• fixes partition tables;
• restores files and creates backup copies;
• selects files in the table;
• copies data from remote partitions;
• creates backup copies of data.

This utility uses several methods to identify problems, as well as the ability to monitor SMART attributes and clean up the hard drive.

Important! The program supports all versions of Windows, but it does not scan/test the drive where the OS is installed.

With it you can scan one or several hard drives at the same time.

"Seagate Seatools" for Windows

The application supports all modern Windows systems. It can be used to do both basic and advanced testing. Simpler than "Seagate Seatools" for DOS, but less powerful.

The process of checking a hard drive for bad sectors is a search for erroneous records and bad sectors located on the drive.

Some of these problems can cause information loss - in most cases, beyond recovery.

Therefore, every user should be aware of their occurrence - both in order to try to correct errors on the disk, and to back up important information to another location.

The principle of formation of bad sectors

Over time, the owner of almost every HDD has to deal with problem sectors.

The principle of their appearance is as follows:

• During the production of disks, sectors are created, with the help of magnetization of which information can be written to the drive.

• Reading and writing information on (especially if the disk is hit or dropped), and sometimes also the influence of computer viruses, lead to a gradual deterioration in the condition of its structure.
• Bad sectors begin to appear on the surface of magnetic disks - areas in which information is stored incorrectly or not recorded at all.

It is possible to eliminate bad sectors, but the system does not automatically perform such actions - the user will have to manually run the scan and repair.

If there are few bad sectors, they are replaced by reserve areas.

When damaged HDD blocks appear, their addresses are reassigned to sectors from the reserve, and no data loss occurs.

Signs of a problem

Among the main signs that problem sectors have appeared on the disk and need to be restored are: The following are worth noting:

• The computer freezes while loading the operating system;
• failure to start the OS - in most cases, the download only reaches a certain point (for example, the Windows logo or the “Welcome” sign) and stops;
• unreasonable and frequent computer reboots;
• errors in the operation of the system, expressed in the inability to launch applications, closing windows and slow response to user actions.

The list of utilities that can be used to solve the problem is quite large.

They are divided into two main groups– those that are already built into the operating system (for example, Windows), and applications from other manufacturers.

The latter can also be divided into paid programs and free versions, which are more popular among domestic users.

Using Windows Tools

To correct errors and bad sectors, Windows OS already contains .

The advantages of using it include the ability to restore areas damaged during operation or as a result of infection of the system with viruses.

Another plus– the ability to start in two ways, in normal mode or.

The utility is capable of checking any physical and logical disks, however, there are slight differences in working with inactive and system areas.

Thus, the stages of checking and restoring a regular partition (which does not contain system control files and the OS itself) will be as follows:

1 Going to the window "My computer".

2 Right-click to open properties of the selected disk.

3 Select a tab "Service".

4 Pressed check disk button.

5 Put checkbox next to check bad sectors.

System volumes on which Windows is installed are scanned differently.

Starting the utility launch coincides with the steps for a regular partition, but when you try to check the disk, a message appears on the screen stating that it is impossible and asking you to do this after a reboot.

After a reboot, the system does not boot - instead, the system HDD partition is checked, the progress of which can be determined by the information displayed on the screen.

And you can run Hitachi Drive Fitness Test not only from Windows, but also in mode if problems with the disk have already made it impossible to boot the system.

Seagate Seatools

The Seatools utility is a free application that whose capabilities include:

• detection of HDD structure violations, including bad sectors and write or read errors;
• fixing bad sectors or overwriting them with zeros, so that in the future the system ignores damaged areas;
• Windows OS problems;
• damage to the system bootloader;

The application works most effectively with Seagate drives.

The average time to fix detected errors (together with the verification process), depending on the size of the partition, can reach 4 hours.

The advantages of the program include its free distribution and the provision of a detailed report.

HDD Health

The free HDD Health program features the ability to receive while checking bad sectors the following information:

• current storage temperature;
• the general condition of the device structure, including whole and damaged sectors;
• a number of other useful attributes.

The utility is distributed free of charge by Panterasoft.

At the same time, the disk health assessment is carried out only using S.M.A.R.T indicators and is less effective than checking the disk with other applications.
