Checking the disk in Windows 7 can be done using GUI and using the command line. Scanning using a graphical interface is more convenient for novice users, while checking using the command line has more options. To start or schedule a disk scan, you must be logged into Windows 7 with administrator rights.

Check Disk: GUI

1. Open the Computer folder.

2. Right-click on the drive you want to check and select Properties.

3. On the tab Service click the button .

4. Select one of the verification options:

• To simply check the disk without attempting to correct errors if any are found, uncheck both checkboxes and click Launch.
• To search for file and folder errors and fix them, select the check box and click Launch.
• To check the disk surface for physically damaged (bad) sectors and try to recover the data stored in them, select Check and restore bad sectors and press the button Launch.
• To check for file and physical errors and try to fix them, select both check boxes and click Launch.

Note. If you select Automatically fix system errors for the drive you are using, you will be prompted to check the drive the next time you boot your computer.

Important: To avoid damaging the disk and the data stored on it, do not interrupt or stop the scan that has started.

At the end of the test, its results will be displayed on the screen.

Check Disk: Command Line

Syntax:

CHKDSK [volume[[path]filename]] ]

For description CHKDSK parameters(command line) used information from the article

Hard disk (HDD) is the most important element of a computer on which all the necessary information, programs and user files are stored. Like any other component, over time the hard drive wears out, its normal operation is disrupted, and failures begin to occur. Along with physical wear and tear, which leads to the appearance of so-called bad sectors (bad blocks), logical errors associated with the file system, indexes and the main file table often occur.

For the time being, you may not experience any problems at work. hard drive, but this does not guarantee that one fine day the hard drive will not die for long. Therefore, it is important to check periodically (once or twice a year) HDD for errors and bad sectors that require correction. Regular monitoring will allow you to track the condition of the media and respond in a timely manner to changes in its condition. Of course, you should not neglect such a proven method of protecting information as backup. The most valuable data must be duplicated on a backup storage device.

Symptoms of a failing hard drive

In most cases, HDDs operate smoothly for several years without requiring special attention. However, in case of improper use ( physical impact, lack of proper cooling) the resource of the storage medium is significantly reduced. In rare situations, there may be a manufacturing defect or sudden failure.

In case of failures in work hard Disk problems may be indicated by the operating system loading too long, files and folders disappearing for no reason, and applications launching slowly. Obvious symptoms of a hard drive losing its functionality are slowdowns in programs and long periods of copying files. If the computer constantly hangs, and nothing but restarting helps, then in the process of identifying the causes, checking the hard drive should be the first point.

Using standard Windows 7/10 tools

You can test the media using standard using Windows. The easiest way is to select the desired hard drive in Explorer, right-click on it and go to the “Service” tab.

Next, click the “Run scan” button and set the scan parameters in the window that opens. If both checkboxes are checked, Windows will automatically correct all system errors and restore damaged sectors during diagnostics.

The results of the audit can be found in the report.

Command line

You can also audit your hard drive using the utility chkdsk called from the command line. In fact, such a check will not differ much from the above option.

So, launch the command line by selecting the required Start menu item. Then enter the command in the window: chkdsk G: /f /r

• G – name of the hard drive being tested (select the drive you will check);
• f – error checking and correction;
• r – detection and recovery of bad sectors.

All information about found errors and bad sectors will be displayed as the diagnostics are carried out.

Third-party programs for checking your hard drive

There are many programs and utilities for finding bad sectors and fixing HDD errors. We will list only the most famous ones.

Victoria

Perhaps the most popular instrument checks hard drives. The program can be launched as in Windows environment, and in DOS mode from a bootable flash drive.

The interface provides five tabs: Standard, SMART, Tests, Advanced and Setup. First of all, go to the section Standard, where in the list of devices we select the hard drive we are interested in. The Drive passport area will display basic information about the HDD.

Next, select the tab SMART and press the “Get SMART” button. SMART (Self-Monitoring, Analisys and Reporting Technology) is a hard drive self-monitoring technology. Those. The hard drive monitors its operation during operation, recording information on a set of parameters that allows one to assess the condition of the media. It is this service information that we are trying to obtain.

After clicking “Get SMART”, either the inscription GOOD on a green background or the inscription BAD! will appear to the right of the button. on red. The second option will indicate that the media is in unsatisfactory condition and will most likely have to be replaced. For a more detailed study of SMART statistics, let's pay attention to the list of parameters on the left. Here we are primarily interested in the attribute 5 Reallocated sector count, indicating the number of sectors remapped. If there are too many of them, then the disk has begun to “crumble,” that is, its surface is rapidly degrading and it is urgent to make a copy of all data. In this case, there is no point in restoring the hard drive.

Chapter Tests makes it possible to check the hard drive for bad sectors, as well as try to “cure” or reassign unreadable blocks. For simple testing of the hard drive, set the switch to Ignore and start the test with the Start button. Sector health is assessed by measuring response time. The smaller it is, the better. Each response time range has its own color code. The slowest blocks are marked in green, orange and red. Sectors that could not be read at all are marked in blue. If there are a large number of “slow” and unreadable blocks, the hard drive should be replaced.

The Victoria program allows you to restore bad sectors, but we will not consider all the nuances of the procedure. Moreover, “treatment” often contributes only to a slight extension of the service life of the storage medium. To reassign bad blocks, perform a check with the mode enabled Remap. If the restoration was successful, do not rush to rejoice. Re-diagnostics of the disk after a certain period of operation. The appearance of new bad blocks will indicate that the degradation of the hard drive is irreversible, and it’s time to find a replacement.

HDDScan

This is another one convenient program to identify problems with hard drives. After launching the application, select the drive that needs to be checked in the Select Drive list.

Below we click on the “S.M.A.R.T.” button and get acquainted with the provided report.

Now let's diagnose the disk surface. Click on the round button to the right of the drop-down list of media and select Surface Tests in the menu that opens.

Click on the Add Test button, thereby adding a test to the list and starting its execution.

You can receive information about the progress of testing in Graph, Map, and Report modes. All blocks are also distributed into groups with corresponding color markings depending on access time.

At the end, a final report is generated.

Perhaps this is all we wanted to tell you about the methods of checking a computer’s hard drive for functionality. We hope the information provided will be useful to you and help you save important data.

If the HDD makes strange sounds or there are problems with writing and reading information, you should use one of the programs to check the hard drive for errors. Depending on the task (checking the disk surface for damage, searching for bad sectors, correcting errors, etc.), different software may be useful.

You can quickly check the disk for errors using standard system tools, but to restore the hard drive you will need special third-party programs. Having learned how to check the health of a hard drive using various utilities, a user of any level will be able to cope with any problems that may arise.

CheckDisk System Service is the simplest hard drive diagnostic program that can't find complex errors or fix bad sectors, but is useful for fixing basic problems. It is available on all versions of Windows OS and can be used to check drives of any type. All users need to know how to check a hard drive for errors with this tool.

The graphical interface version of the utility is most convenient for novice users. You can launch it through the disk management menu, which can be accessed in two ways:

1. in Windows XP/Vista/7 - select “Manage” in the context menu of “My Computer”, then go to the desired menu;
2. in Windows 8/10 - press the Win+X combination and select the appropriate item.

In the window that opens, select the device that needs analysis, right-click on it and select “Properties” from the drop-down menu. By going to the “Service” tab, you need to run the hard drive diagnostic program.

The system will check and automatically correct errors if the disk is in this moment not busy with reading or writing processes. Otherwise, the program will offer to test after rebooting the PC. If necessary, in the scan results window you can see detailed information about the status of the HDD.

The GUI version does not always help, since it is sometimes necessary to check the status of the hard disk safe mode or without starting the operating system at all. In such cases, the console comes to the rescue; you can launch it before the system starts using boot disk.

Once you open the recovery console, you need to run the chkdsk /f command, which will check all connected drives. In some cases, this will help fix the error. However, in most situations, if a HDD failure has made it impossible to start the system, a more in-depth check of the hard drive’s condition will be required.

To take advantage console command from inside the system you need:

• launch the command line (via Win+X or by entering cmd in the “Run” window);
• enter the chkdsk command indicating the letter of the partition being checked and additional flags;
• Confirm the operation by pressing Y.

Checking the HDD via the command line will be a little faster than when using the GUI version of the program; the results will be shown here in the console.

The Linux system also has standard tools - hdparm and smartctl, launched from the console.

Simple programs for quickly checking HDD

If standard utilities are not suitable, hard drive diagnostics can be carried out using simple third party programs. They allow you to get more information about the condition HDD health, but in case of serious problems they will not be suitable, since they cannot be used to correct breakdowns.

HDDScan is a free program that performs analysis in two modes:

• according to S.M.A.R.T. indicators;
• linear processing.

The tool evaluates the read and write speed of various sectors, marking the “slow” cells. During the analysis, the program ensures that the tested hard drives do not overheat; at the end of processing, the user is presented with a full report.

HDDScan good versatility. The utility allows you to check disks for errors regardless of the type of device: it can either check an external hard drive or analyze a RAID array, SSD drive or memory card.

Crystal Disk Mark has only one function - it evaluates the read and write speed. Despite this, it is often used, since it is still possible to check the hard drive for serviceability using just two indicators.

The test uses different algorithms, one of which is sequential recording mode. The program gradually fills all the space on the drive with blocks of a size specified by the user, after which it cleans the HDD. The same technique is used by hard drive manufacturers to check product quality. Its disadvantage is that it accelerates the wear of SSD drives.

CrystalDiskInfo And DiskCheckup They are similar in their set of functions, differing only in the interface. They check the status of the hard drive using S.M.A.R.T. algorithms and compile a history of checks, which allows you to track the dynamics of changes. CrystalDiskInfo has more options for visualizing history. For example, you can create a graph, not just get a written report.

Another feature of these programs is a convenient notification system. In-depth hard drive tests usually take a long time. If the user needs to step away from the computer, they can turn on critical notifications. HDD errors by E-Mail.

Programs from hard drive manufacturers

Some HDD manufacturers have developed their own utilities for analyzing the status of the hard drive. They are intended for use with devices of the same name; diagnosing a hard drive from another company is possible with their help, but this must be done carefully. Unlike simpler programs, these utilities have versions in different languages, including Russian. Which program is better to analyze the HDD status?

The proprietary program from Seagate exists in two versions: a standard version for running under Windows and a DOS version in ISO image format, from which you can make bootable USB flash drive. It is recommended to use the second option, since the check in this case will be more accurate and efficient.

SeaTools uses part of the S.M.A.R.T indicators. to test the hard drive without giving away details about each item. Three tests can be performed:

1. short self-test of HDD;
2. short rapid test;
3. a long-term check in which all sectors are read sequentially.

As the scan progresses, the program automatically corrects any errors found.

Owners of hard drives from WD should know how to check the performance of hard drives using proprietary software from this manufacturer. The range of its capabilities is similar to that of the program from Seagate, but is somewhat expanded and allows for more in-depth work with the affected device.

There are two additional functions:

1. deep disk formatting - the program writes zeros to all sectors, permanently destroying information;
2. blocking access to bad sectors - the program marks bad blocks, preventing the writing of new information to them.

Unlike SeaTools, this program for diagnostics, the HDD can be freely used with devices from any manufacturer to check the hard drive for errors - no problems were identified with this.

Deep testing software

If you need not only checking your hard drive for errors, but also correcting bad sectors, you cannot do without a complex software, which carries out the most in-depth analysis of the HDD state.

Victoria HDD

According to many users, Victoria HDD is the best software for detecting hard drive problems. The program gained this reputation due to its wide range of functions.

Victoria exists in two versions:

• with a graphical shell for use from inside Windows;
• with a DOS shell to create a boot disk.

It's better to use the second version. Diagnostics of the HDD outside the system allows you to achieve better results, so it is always recommended to follow the principle “if possible, test the disk from the boot disk.” As a last resort, you can use a LiveCD of another OS, for example, Linux distribution like Ubuntu.

Victoria HDD has a variety of functions:

• quick and complete disk scan;
• reassignment of bad sectors and their restoration;
• checking the status of contacts in the IDE or SATA cable;
• equipment performance analysis;
• viewing S.M.A.R.T. indicators.

When checking, you need to pay attention to the access time to sectors. It should not exceed 200-600 ms. You can also view the temperature of the disk during operation, but this is not so important.

HDD Regenerator

HDD Regenerator is a program for professional hard drive recovery. It not only marks bad sectors as unused, but also tries to revive them. For this, not the standard deep formatting method is used, but a proprietary algorithm based on transmitting signals of different levels to the sector. Despite its professional level, inexperienced users can also use this software, since testing a hard drive with its help is not difficult thanks to its convenient Russian-language interface.

Program features:

• ensuring data safety - it works only in read mode;
• support for different file systems;
• the ability to scan the disk surface;
• real-time monitoring.

The program is not suitable for everyone, since you can check your hard drive for functionality for free, but you will have to pay $90 for the sector recovery function.

If you don’t want to pay, you can use TestDisk - free program, which can repair the partition table, boot sectors and MFT. It also detects bad sectors, can recover deleted information and fix errors file system. The only drawback is the lack of a graphical interface; you have to work from the console.

If after HDD checks and if all problems are corrected, the computer has not stopped working incorrectly, it is worth checking the registry. Perhaps the failures are caused not by hardware failure, but by internal system errors.

In this article you will find a guide to using chkdsk, links to programs that allow you to comprehensively test your hard drive, as well as instructions for them. Additionally, the article explains how to check hard sections disk using built-in Windows tools.

Windows Check Disk Utility (chkdsk)

Windows OS has its own disk checking utility. It can be launched from the GUI or from the command line.

Running disk check from the GUI

Open the window My computer, right-click on the drive or partition you want to check and select from context menu paragraph Properties. In the disk properties window, go to the tab Service and press the button Run check.

In the next window, click the button Launch.

The scan of the non-system partition will begin immediately. If you are checking system partition Windows 7, you may see a message saying that it cannot be completed at this time.

It's ok because system partition used by the operating system. Click the button Disk check schedule. To run the scan, you must restart your computer. After the computer restarts, the disk check will be performed before the operating system starts.

Run disk check from the command line

Below is an example of running a partition check C from the command line.

Chkdsk c: /f /r

Note. Command line required run with administrator rights.

In Windows 7, as in the case of checking the system partition from the GUI, after executing this command you will see a message stating that the scan cannot be completed.

Enter Y and restart your computer to start checking.

Additional information about the command line parameters of the utility chkdsk you can get it by running it with the key /? , or on this page.

Run a disk check if the system won't boot

If operating system does not boot due to errors on the disk, you can check the disk using installation disk Windows.

Windows 7, 8.1, 10

1. Boot into the recovery environment and open a command prompt (instructions for Windows 8 and later , Windows 7)
2. IN command line enter the command chkdsk c: /r

Windows XP

If the problem occurs in Windows XP, use the Recovery Console. After booting from the installation disk into the console, run the command

Chkdsk c: /r

For more information about the Recovery Console, see the following Microsoft Knowledge Base articles:

• Installing and using the Recovery Console in Windows XP
• Enable automatic administrator login when using the Recovery Console

Hard drive diagnostics using third-party programs

If after checking the hard drive with the utility chkdsk If you continue to experience critical errors related to your equipment, it is worth carrying out more thorough testing using specialized programs. As a rule, hard drive manufacturers' utilities or programs such as Victoria or MHDD.

Attention! Before testing hard disk using third-party programs, you need to back up all data.

Hard drive manufacturer utilities

Diagnostic utilities may be on the CD that came with your hard drive. In any case, they can be downloaded from the hard drive manufacturer's website. Links to some manufacturers' download pages are provided below.

• Western Digital: Data Lifeguard Tools (you must select the disk model).
• Seagate: SeaTools.
• Hitachi: Drive Fitness Test.
• Samsung: Shdiag.

Diagnostic tools from other manufacturers can be found on their websites.

Victoria

program Victoria, designed for in-depth testing of the health of the hard drive, can be found at this link on the website hdd-911.com.

• Excerpts from the official documentation of the Victoria hard drive test

MHDD

The MHDD program is also capable of comprehensively testing the hard drive and fixing errors on it. You can download it from this link from the website MHDD.ru.

You will find more information at the following links:

The disk is in perfect order - what next?

If no errors are detected on the hard drive, it is most likely not causing critical errors. It is possible that the problem lies in faulty RAM or the power supply does not have enough power to ensure the operation of all devices. you can check RAM and drivers, as described in the articles linked below.

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!
With rating Victoria programs and MHDD agree, I myself use Victoria for serious diagnostics, but I try to test other programs, everything is learned by comparison.)

Dmitriy

at checking hard disk, the standard program on Windows 7 says that bad clusters have been 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 disconnecting the TV from the network, you remove 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, wise? 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 they had already laid graphical capability 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 there “ standard means» trim the size of the logical volume from the desired end. 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 sources uninterruptible power supply 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 fine 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 diagnostics of hard Windows disk(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. It's not about 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 launch chkdsk utility disk check, if both “daws” are checked, 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 do not run a disk check, then there is no reason to worry, everything works fine, does not glitch, does not crash. So, in connection with this, the question is - maybe there is no need to spoil your mood. On the site Microsoft solutions I didn’t find any problems with these file system errors, 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?
