How to check the hard drive on a laptop

Diagnostics and elimination of errors on the hard disk

Quite often, the slow operation of a computer or laptop is associated precisely with errors and malfunctions in the hard drive. In this article, we will figure out how to check the health of a hard disk using Windows tools and specially designed programs.

Hitachi Drive Fitness Test

An excellent program designed to find and fix problems with drives. It is universal, as it can diagnose any drives. With its help, you can extremely quickly find out the current position of the hard drive, as well as get additional information about it.
Includes:

  • Fast but thorough check;
  • Support for all components;
  • Monitoring;
  • Data statistics;

This utility is suitable for all devices and can be used even on a netbook.

TestDisk

Designed to determine the status and test drives. In addition to simple diagnostics, it also detects bad sectors and fixes any errors found. Its main functions include:

  • Analyze the current state of the hard drive;
  • Search for broken sectors;
  • Recovering deleted partitions;
  • Fix MFT;

Checking external hard drives;
In addition, the utility has a number of other functions that are related to recovering deleted files.

Checking the hard disk for errors via the command line

To start the scan, you must perform the following steps: go to “Start / All Programs / Accessories / Command Line”. Right-click and click “Run as Administrator”. There are other ways to run the command line.

In the window that appears, execute the command “chkdsk disk_partition: check_parameters”. It should be borne in mind that this method works exclusively with disks that have been formatted in FAT32, NTFS or RAW (a separate article is devoted to this format).

An example of a command is “chkdsk C: / F / R”. Its essence is as follows:

  • Section C will be checked for errors;
  • Found problems will be automatically corrected (parameter F is responsible for this);
  • Bad sectors will be checked and information restored (parameter R);

If you want to diagnose the drive that the system is currently using, you will see a special notification. You will be prompted to perform a check the next time you boot your computer. To agree with this, press Y, to refuse. N. Based on the results of the check, information about the checked data, the number of bad sectors and the errors found will become available to you.

For a complete list of options, run chkdsk with a question mark as a parameter. But if you need a routine check for errors and sectors, then the above information will be enough for you.

It happens that the errors found during scanning are not always possible to immediately fix, it is likely that this is due to the program running at that time. In this situation, an offline scan of the drive will be required: it is disconnected from work, diagnostics are carried out, and then it is connected back. To do this, enter into the command line “chkdsk C: / f / offlinescanandfix” (C:. disk partition). If it is not possible to disable it, then the check will be performed at the next reboot.

If necessary, after checking, you have the opportunity to study the check log. For this you need:

  • Go to Windows Logs / Applications;
  • Right-click on Application / Search;
  • Search for the word Chkdsk;

Program check

Of course, the above method is not always effective. Therefore, we will look at a number of programs like Victoria. They will allow you to carry out the most thorough analysis of the state of the hard drive on a computer or laptop.

Victoria

Utility for diagnostics and testing of the hard drive. It will help you not only find problems in its work, but also fix them.
The program has a number of advantages and useful functions:

  • Reads the hard drive’s passport and provides detailed information;
  • 5 diagnostic modes;
  • Eliminates crashes;
  • Displays unstable areas;
  • Hides defects;
  • Evaluates media performance.

Victoria is one of the best to date. It is able to solve problems with bad sectors and quickly bring any type of hard drive to a working state. However, a separate article was devoted to her, which I certainly recommend that you familiarize yourself with.

HDD Regenerator

One of the most effective programs for assessing the health and troubleshooting drives. It makes it possible to get information on the current state of Smart of the selected device and full control over it.
Among the main features are:

  • Simple and intuitive interface;
  • Full safety;
  • NTFS and FAT support;
  • Pre-scan mode;

HDD monitoring in real time;
That is, with the help of the regenerator you can test the hard drive as efficiently as possible.

Built-in programs for checking the hard drive

The standard software is compatible with both hard disk drives (HDD) and solid state drives (SSD). They are also suitable for not only internal but also external drives. You can find the type of your drive and other information about it in the documentation for the device.

Windows

You can check the disk in Windows using the utility available in the drive’s menu. To run it, open Explorer and right-click on the disk you want to diagnose. Select “Properties” → “Tools” → “Check”.

If you see the option “Check and repair bad sectors”, check it. Follow the instructions on the screen until the check is complete. Sometimes the process takes several hours: the total time depends on the speed of the disk and the power of the computer. If you are testing a laptop drive, connect the device to the mains.

On some computers, hard drive check tools are built right into the BIOS. For example, on HP notebooks, the Primary Hard Disk Self Test option is available, which can be used even when the hard drive refuses to boot Windows.

You may have a similar feature on your device. You can enter the BIOS by pressing F2, F8 or another key that is displayed immediately after turning on the computer and look for a verification tool. When you find it, run diagnostics and follow the prompts on the screen.

How to check your hard drive for errors and repair it

What to do if programs slow down, files do not open or copy for too long, and the system complains about disk errors.

As a result of software glitches, physical damage or wear and tear, various problems can arise with the drive. Among them. failures in the file system, or the so-called bad sectors (bad sectors). damaged areas of disk space.

Windows and macOS have built-in utilities to diagnose and resolve these issues. There is also a separate software that analyzes disks more thoroughly.

macOS

You can use Disk Utility to check drives on Mac computers. Find and run it in Finder → Applications → Utilities. Then select the drive in the sidebar, click “First Aid” and follow the system prompts. The utility will search for problems and, if found, will try to fix them. In rare cases, the process can take several hours.

Third-party programs for checking the hard drive

The standard diagnostic tool is sufficient for most situations. But nevertheless, it can miss some mistakes.

Hard drive manufacturers offer free software to scan their devices more thoroughly. Examples include SeaTools for Seagate drives and Data Lifeguard Diagnostic for Western Digital drives. These utilities are easy to use and often contain detailed instructions in Russian. You can find the program for your hard drive on the manufacturer’s website.

Among Windows users with a certain baggage of technical knowledge, the Victoria utility is very popular, which is compatible with disks of different brands. It performs an in-depth analysis of the drive and repairs it. But the developer stopped supporting it long ago, so there is no guarantee that Victoria will be suitable for all modern devices. In addition, it is complex and in the hands of an inexperienced user can damage the hard disk. So it’s hardly worth recommending it to beginners.

Whether a particular program supports SSDs or only HDDs, you can find out from its official description. This also applies to support for external drives.

If your chosen diagnostic tool finds errors that it cannot fix, then there is a risk of losing personal data. In this case, it is advisable to copy important files to another medium and try to restore Windows or macOS. If the hard drive continues to malfunction, it is best to replace it.

How to check the hard drive on a laptop

Hard disk (hard drive, HDD) is the main storage of information on your laptop or PC. Its name is associated with physical properties: unlike floppy disks, disk data is recorded on hard plates, which can be made of aluminum or glass using the magnetic recording principle. Very often, system slowness is associated with a malfunctioning HDD, therefore, before sending a laptop for repair, learn how to check the hard drive on a laptop and try to fix the errors you find yourself. How to do this, we will tell you in Russian in this article.

How to Check Your Laptop Has Hard Drive or SSD (Easy)

HDD diagnostics built-in tools of the Windows operating system

Regardless of which version of the OP you are using, the system has special built-in functions and utilities with which you can test the hard drive on a laptop.

Option one: in the “My Computer” folder, select the hard drive that you want to scan for errors. Next, click Properties Service Run Check. The computer can simply do a reporting analysis, or it can immediately correct HDD errors (for this, check the boxes for requests for automatic corrections of system errors and restoration of system sectors). After this setting, click the Start button. If the system displays an error due to the impossibility of checking the hard disk that it is using at the moment (this usually happens when scanning drive C), select “Schedule disk check”. After that, you just need to restart the laptop (or PC), and during boot up, a test for problems will occur. Its duration can fluctuate from a minute to an hour, and after that the OP will be launched.

Option two: the check disk utility. Detects errors in the file system of the hard disk or floppy disk and fixes them. To start it, open the command line console (always with administrator rights) and enter the command CHKDSK [volume [file_name]] / F / V / R / X / I / C / L [: size]] / B. Where

“[Volume]” is the disk being checked (written as a colon letter, for example C :),

“[File name]” files to check (if you want to check the entire disk, you do not need to enter this),

/ V displays the full path and name of each file,

/ R executes the command to search for bad sectors and restore the contents, which survived (for its execution, the presence of the / F command is required),

/ X will pre-unmount the volume if necessary,

/ I will enable less strict checking of index elements, / C will set the command to skip checking loops inside,

/ B Enables re-evaluation of damaged clusters.

At the same time, the full set of commands is rarely used, the most common will be the / F and / R commands (when entering the letters for all other commands in the console, you just need to skip, for example, chkdsk D: / F / R). After entering the command in the console line to check the disk for errors, you will be prompted to execute this command the next time you start the system, press Y Enter to confirm and reboot.

P.S. You can find out how to run the command line of the administrator of your version of the operating system on the Internet; for example, in Windows XP, to open it, you need to go to Start All Programs Accessories Command Prompt.

It is possible that performing a disk check using the console and the utility is not clear to you, especially if you are not very familiar with the system. Well, do not despair: specially for such cases, special software has been developed and released, which will help you test not only clearer, but also more complete. For those who still have not decided the question of how to test the hard drive of a laptop or desktop computer, we have collected the most popular free programs that will cope with the task.

Diagnostics of the hard disk for errors using various programs

The most common program for scanning your hard drive for errors is Victoria. Although it should be noted right away that its use also requires some experience and skill in handling software, it is not intended for beginners. You can download the program image for free from the official website. After that, we take the following steps in the following sequence:

  • Unzip the downloaded data;
  • Burn data to CD / DVD;
  • Boot from the disk where the files were written;
  • Choose the Victoria program for your device;
  • After starting the program interface, we find the required disk (if the program itself has not detected it, press F2 for this): press P and select the desired volume (by the way, for the SATA interface, select the HDD port “Ext. PCI ATA / SATA”);
  • To check the surface of the disk, press the F4 key;
  • After a physical check of the HDD surface of the laptop / computer, an error check is performed with the correction of malfunctioning areas;
    The procedure is long, usually from 40 minutes to 2-3 hours.
  • Finish: remove the disk and restart the system.

Well, despite the popularity of this software, it is obvious that Victoria, being a powerful tool for diagnosing and fixing disk errors, is not intended for beginners. But besides it, there are several other good programs that will cope with such a function as checking the HDD on a laptop / PC.

Seagate SeaTools is a free program for beginners in hard drive testing. It can also correct the identified errors, which means that it is in no way inferior to the common Victoria program.

The program tests drives of all brands. You can download it for free from the manufacturer’s official website. It can work on two platforms. as a utility for Windows (for that we download “SeaTools for Windows”) or as an iso image that is loaded onto a separate disk, like the Victoria iso image (for this we download “Seagate for DOS” from the site). At the same time, its significant advantage over the previously reviewed program will be a complete Russian-language reference description-instruction on how to check the HDD on a laptop / PC (help section). It is she who will help to understand the processes and the result of the disk check.

Active users of such software will agree that the Seagate SeaTools and Victoria programs are perhaps the most useful tools in identifying and fixing hard drive errors. If the first one is suitable for beginners, especially for users from Russia, since it has a Russian-language version, then the second one will be useful for experienced users, or at least for those people who can freely understand English vocabulary related to computer technology. There are other programs that will allow you to do testing, but they are either suitable for a certain type of disks, or they do not determine as much as possible the errors of hard drives; that is why, we have analyzed only the best options for checking HDD.

And finally, our general advice for all those who feel abnormal operation of the HDD on a laptop or stationary computer (for example, its excessively noisy operation) and in general for all those who have personal computers: be sure to back up your data and be prepared for a long repairing or even replacing the hard drive of your equipment.

How to find out the real volume of the hard drive

For a better understanding, manufacturers and sellers indicate the traditional disk sizes: 40, 60, 120, 160, 320, 500, 640 GB and so on. However, in reality, it is always less than stated, because:
1 GB = 1024 MB
1 MB = 1024 KB
1 KB = 1024 bytes

and manufacturers round up to 1000 when calculating. Below is a table of correspondence between the marking volume of the HDD and the real.

Drive capacity Total, bytes (rounded off) Actual size
40 GB 40,000,000,000 37.25 GB
60 GB 60,000,000,000 55.88 GB
80 GB 80,000,000,000 74.51 GB
100 GB 100,000,000,000 93.13 GB
120 GB 120,000,000,000 111.76 GB
160 GB 160,000,000,000 149.01 GB
200 GB 200,000,000,000 186.26 GB
250 GB 250,000,000,000 232.83 GB
320 GB 320,000,000,000 298.02 GB
400 GB 400,000,000,000 372.52 GB
500 GB 500,000,000,000 465.65 GB
640 GB 640,000,000,000 595.84 GB

To verify this, right-click on the My Computer shortcut and select Manage. In the utility that opens, go to the Storage Devices tab. Disk management

In our case, the utility shows 465.65 GB, which corresponds to the 500 GB marking.

How to find out the hard drive model

As in the previous method, right-click on the My Computer shortcut and select Manage. In the opened computer management utility, open the Device Manager tab. Here expand the Disk devices item and you will see the hard drives installed on your computer.

In our case, there are two of them. Hitachi HTS545050A7E380 and SanDisk SSD i100 24 GB. First. traditional HDD, second. solid state SSD.

There are few cases when you need to find out the model of your hard drive. Most often, a similar question is asked when the Winchester ordered to live long. errors appear during operation, or the OS does not boot at all due to a non-working disk. It happens that you need to determine your HDD in order to replace it with a more capacious one, or this information is just interesting for you.

In any case, problems with a hard drive are those that are eliminated in workshops, since repairing computers at home is advisable only when the problem can be eliminated quickly and efficiently. Diagnosing HDD malfunctions takes a long time, which means that you can quickly only replace the problem disk with a new one.

The most primitive way to find out your hard drive. get it out of the system unit or laptop case. To do this, turn off the power (remove the laptop battery), unscrew the system unit (or the bottom cover on the bottom of the laptop) and take out our HDD, on which all the information of interest will be visible. manufacturer, volume, speed of work, country of production and other parameters.

If you have no desire to disassemble a laptop or untwist the system unit, then we can find out all the information of interest using the program method.

How to find out all the information about your hard drive

We have already turned to the AIDA64 program for help when we were looking for our network card, the temperature of the processor and video card, battery wear, etc. This utility will help us this time too.

You can familiarize yourself with the AIDA64 program and download it for free on this page of our website.

Launch AIDU on your computer and go to the Data Storage tabs. ATA. At the top of the window, select the required hard drive, if there are several, and the program will show all information about the hard drive. The report is split into parts, the information we need is titled ATA Device Properties and Device Physical Data.

As you can see, everything is elementary and absolutely simple if you know what tools to use to find information.

Checking for errors in HD Tune

The next step is to check the health of the hard drive using specialized programs. Such programs allow you to check the hard drive for errors and identify existing problems, even if they do not appear in normal use. Let’s start with the free HD Tune program (or its paid version HD Tune Pro).

In order to check the hard disk for errors, run HD Tune, go to the tab and click on the “Start” button.

Then HD Tune will start checking the hard disk for good condition. During the check, you will be able to observe this process. Normal areas of the hard drive will be marked in green, and damaged areas in red.

On a fully functional hard disk, there should be no damaged (red) blocks at all, the entire surface should be marked in green.

Blue Screen of Death BSOD

At best, when documents are damaged, the BSOD screen pops up. In this case, try to put the system on a different hard drive and save the information this way.

These screens indicate that the system is malfunctioning.

Signs of hard drive problems

However, before trying any of the appropriate solutions, you can try to diagnose the problem based on the behavior of the computer in order to subsequently select the optimal program.

The fact that the PC operating system starts to work with noticeable inhibitions, takes a long time to load, processes even small files with significant delays, most likely indicates that bad sectors appeared on the hard drive in the amount that makes it difficult for the OS to work stably.

If there is no decrease in the speed of the operating system and file processing, but programs close spontaneously, they freeze or work unstable, there are probably errors at the level of the disk file system.

In many cases, the occurrence of problems in the operation of the hard drive is caused by the actions of a computer virus. Therefore, before using this or that hard disk testing software tool, as well as fixing the detected errors, it is recommended to scan the computer with an available antivirus program. It is highly desirable that the anti-virus databases in it were the most recent. As soon as all found viruses are removed from the PC, you can already start checking the hard drive. Consider what means can be used in this case.

Using the command line

To perform the check, you need to perform the following steps: go through “Start” in the “All Programs” menu, then select “Standard” and find the “Command Line” section. Right-click and select “Administrator”.

In the field we write “chkdsk disk: check_settings”. It is necessary for Honor that this method can only work with mass storage devices formatted in FAT32.

  • Drive D is checked.
  • Errors are corrected automatically (F command).
  • All sectors are checked and data is restored (R command).

If you need to diagnose the disk that is currently used by the system, a message will appear, where you are prompted to check when you restart the PC. Y. agree, N. refuse. After checking, information about the number of errors and bad sectors will appear.

Victoria HDD

The next popular solution for testing hard drives is Victoria HDD. It can be noted that this program allows you to both test the hard drive on Windows 7 (8 or any other), and check the hard drive through the DOS command line.

This feature increases the versatility of the considered solution. In addition, the corresponding software has very good functionality.

So, the program allows you to test the hard drive for bad sectors, reassign their use, classify areas of the hard drive surface into different categories depending on the speed of reading files from them.

READ  Why There Is No Sound On Laptop

If the English graphic version of the program in question is used, you must run it, then go to the Tests tab. There are tests on the surface of the hard disk platters. If necessary, you can configure the program’s actions when bad sectors are detected:

  • ignoring the problem (with its subsequent reflection in the test results);
  • reassignment of sectors;
  • deleting sectors;
  • restoration of damaged areas of the disk.

If necessary, you can use each of the specified operating modes of the program in turn.

Laptop reboots all the time

The main reason lies in the boot sector, which was attacked by the virus, creating a constant restart cycle of the PC. The virus program forces the OS to access the boot sector and continually reboot the laptop. This can quickly damage the drive.

Fixing file system errors: using Windows tools

How do I test my PC hard drive for file system errors? For these purposes, as a rule, it is sufficient to apply the built-in Windows solutions. They are found in almost all modern versions of this operating system for desktops and laptops. The main one will be the “Check Disk” program or Chkdsk.

This solution can be used both through the graphical interfaces of the operating system and through the command line. The first option is usually easier for a novice user, while the second may require more skill in using Windows diagnostic tools.

To use the utility in question, you need to go to the “Computer” section, then right-click on the hard disk icon. There may be several of them, in this case it makes sense to check each one in turn. After right-clicking on the hard drive icon in the menu that opens, select the “Properties” option. In the window that appears, go to the “Service” tab. Then click on the “Check” button and follow the instructions.

In some versions of Windows, the utility in question is not configured to test logical drives that host OS system files. But in this case, the “Check Disk” program provides an option: initiation of testing the hard drive at the next boot of the operating system. You can select it and immediately restart Windows: during the startup process, the system itself must ask the user for permission to check the disk on which the system files are located.

So now we know how to test a hard drive using the popular built-in Windows tool, Chkdsk. This solution allows you to efficiently correct file system errors. But what if the alleged failure of the hard drive is associated with the appearance of bad sectors on it? How to Test a Laptop or Desktop Hard Drive for Corresponding Damage?

The widest range of solutions can be used for this purpose. The most popular of them include such programs as:

  • Data Liferguard Diagnistic.
  • HDD Scan.
  • Ashampoo HDD Control.
  • Victoria HDD.
  • AIDA64 (formerly Everest).
  • MHDD.

How to check your hard drive for errors via the command line

To check the hard disk and its sectors for errors using the command line, you first need to run it, and on behalf of the Administrator. In Windows 8.1 and 10, you can do this by right-clicking the Start button and selecting Command Prompt (Admin). Other methods for other OS versions: How to run the command line as administrator.

In the command line, enter the command chkdsk drive_letter: check_parameters (if nothing is clear, read on). Note: Check Disk only works with disks formatted in NTFS or FAT32.

An example of a working command may look like this: chkdsk C: / F / R. this command will check the C drive for errors, and errors will be corrected automatically (F parameter), bad sectors will be checked and information recovery will be attempted (R parameter) Attention: checking with the parameters used can take several hours and it seems to “hang” in the process, do not perform it if you are not ready to wait or if your laptop is not connected to an outlet.

In case you try to check the hard drive that is currently in use by the system, you will see a message about this and offer to check after the next restart of the computer (before the OS is loaded). Enter Y to agree or N to refuse verification. If during the check you see a message stating that CHKDSK is not valid for RAW disks, then the instruction can help: How to fix and restore a RAW disk in Windows.

In other cases, a check will be immediately launched, as a result of which you will receive statistics of the checked data, errors found and bad sectors (you should have it in Russian, unlike my screenshot).

You can get a complete list of available parameters and their descriptions by running chkdsk with a question mark as a parameter. However, for a simple check for errors, as well as for checking sectors, the command given in the previous paragraph will suffice.

In cases where the check finds errors on the hard drive or SSD but cannot fix them, it could be because a running Windows or programs are currently using the drive. In this situation, starting an offline scan of the disk can help: in this case, the disk is “disconnected” from the system, a check is performed, and then it is mounted again in the system. If you cannot disable it, then CHKDSK will be able to check the next time the computer is restarted.

To perform an offline disk check and fix errors on it, in the command line as an administrator, run the command: chkdsk C: / f / offlinescanandfix (where C: is the letter of the disk being checked).

If you see a message stating that the CHKDSK command cannot be executed because the specified volume is in use by another process, press Y (yes), Enter, close Command Prompt, and restart your computer. The disk check will start automatically when Windows 10, 8, or Windows 7 starts to boot.

Additional information: if desired, after checking the disk and booting Windows, you can view the Check Disk check log using the event viewer (WinR, enter evenTVwr.msc) in the Windows Logs. Application section by searching (right click on “Application”. ” Search ») by keyword Chkdsk.

Checking the hard drive in Windows Explorer

The easiest way to check HDD in Windows is to use File Explorer. In it, right-click on the required hard drive, select “Properties”, and then open the “Service” tab and click “Check”. In Windows 8.1 and Windows 10, you will most likely see a message stating that you do not need to check this disk at this time. However, you can force it to run.

In Windows 7, there is an additional option to enable checking and fixing bad sectors by checking the appropriate boxes. You can still find the verification report in the Windows Application Event Viewer.

Checking your hard drive for errors in Windows

This beginner’s guide shows you step-by-step how to check your hard drive for errors and bad sectors in Windows 7, 8.1 and Windows 10 through the command line or in the explorer interface. Additional tools for checking HDD and SSD that are present in the OS are also described. Installation of any additional programs is not required.

Despite the fact that there are powerful programs for checking disks, searching for bad blocks and fixing errors, their use for the most part will be little understood by an ordinary user (and, moreover, can even harm in some cases). The built-in system check using ChkDsk and other system tools is relatively easy to use and quite effective. See also: How to check SSD for errors, SSD health analysis.

Note: if the reason why you are looking for a way to check the HDD is the incomprehensible sounds it makes, see the article Hard disk makes sounds.

Checking Disk for Errors in Windows PowerShell

You can check your hard drive for errors not only using the command line, but also in Windows PowerShell.

In order to complete this procedure, start PowerShell as administrator (you can start typing PowerShell in the search on the Windows 10 taskbar or in the Start menu of previous OS, then right-click on the found item and select “Run as administrator”.

In Windows PowerShell, use the following options for the Repair-Volume command to check the hard drive partition:

  • Repair-Volume.DriveLetter C (where C is the letter of the drive being checked, this time without a colon after the drive letter).
  • Repair-Volume.DriveLetter C. OfflineScanAndFix (similar to the first option, but to perform an offline scan, as described in the chkdsk method).

If, as a result of the command execution, you see the message NoErrorsFound, it means that no errors were found on the disk.

Additional options for checking disk in Windows 10

In addition to the options listed above, you can use some additional tools built into the OS. In Windows 10 and 8, disk maintenance, including checking and defragmenting them, occurs automatically on a schedule when you are not using your computer or laptop.

To view information about whether any problems with disks were found, go to the “Control Panel” (you can do this by right-clicking on Start and selecting the desired item in the context menu). “Security and Service Center”. Open the “Maintenance” section and in the “Disk Status” item you will see the information obtained as a result of the last automatic check.

Another feature introduced in Windows 10 is the Storage Diagnostic Tool. To use the utility, run Command Prompt as administrator, then use the following command:

Execution of the command will take some time (it may seem that the process is frozen), while all connected drives will be checked.

And after the completion of the command, a report on the identified problems will be saved in the location you specified.

The report includes separate files containing:

  • Chkdsk check information and error information collected by fsutil in text files.
  • Windows 10 registry files containing all current registry values ​​related to connected drives.
  • Windows Event Viewer log files (events are collected within 30 seconds when using the collectEtw key in the disk diagnostic command).

For an ordinary user, the collected data may not be of interest, but in some cases it may be useful to diagnose problems with the operation of drives by a system administrator or other specialist.

If during the check you have any problems or need advice, write in the comments, and I, in turn, will try to help you.

Hello! Today, when the PC was turned on, CHKDSK was launched, and made a check in 3 stages (5 minutes). Is this a scheduled task or is there a problem? This is the first time I see this.
The HDD disk is already “retired” (32,700 hours of work; 7 years of the disk). CrystalDiskInfo says “Good”. Reassigned sectors in Raw “by zeros”, exactly like unstable sectors and unrecoverable sector errors.

Hello.
Unlikely planned, rather a failure (for example, improper shutdown, or power off while he was in sleep / hibernation). Don’t worry yet.

Hello!
I ran a disk check for errors. no errors were found. Then defragment the disk. All by standard means through a conductor. The free space on the system disk has decreased by 2.5 GB (.) This is very noticeable for me. Launched disk cleanup and usually, and in advanced mode, and with additional parameters. nothing helped. What could be the reason? (SSD disk. Win7) And is it possible to somehow clear these 2.5 GB? I don’t understand how the defragmentation “ate” 2.5 GB.
thank!

Hello. It is unlikely that defragmentation, most likely still something was downloaded (updates, etc) while it was defragmented.

Thanks for the answer. It is unlikely that an update. the computer, during defragmentation, was not connected to the Internet at all, and the size of such an update (2.5 GB!) There are no other options?

Do not come to mind. Defragmentation shouldn’t do anything like that. Temporary files may exist, but there are no other ideas.

Thanks for trying to help! I’m trying to figure it out on my own. I used the Wiz Tree program, and after analyzing it, I found that the SystemVolumeInformation folder was “swollen” by exactly 2.5GB. Before checking and defragmenting the disk, this was not the case (I monitor the system) I did not find any other reasons for the disappearance of free space. But now I don’t know why this folder is so “swollen”, and how to clean it.

Well, in general, this folder from the “large” can contain system restore points.

Yes, I agree. But, as I said, I follow the system and this folder in particular. Its weight did not exceed 500MB. Since everything worked stably, I usually left one last (maximum two) restore points. so that there would be more free space. When after defragmentation 2.5 GB “disappeared”, the first thing I did was clean the disk in advanced mode with deleting restore points. I cleaned it with a regular tool through a conductor, so by definition I could not break anything in the system. However, there is no more space, so this folder is unlikely to become “swollen” due to restore points. Already I began to lean towards the fact that I damaged part of the blocks on the SSD with this defragmentation. which, in general, I think is unlikely. I ran a check through the command line (chkdsk C: / f). everything is fine. Through Wiz Tree, analyzed everything again. The folder “Sys Vol Inf” was “swollen”. I found 4 files in it, which in total are 2.5 GB and the date of their modification coincides with the date of defragmentation. And the Wiz Tree program makes it possible to delete them, but this is where a dilemma arises. there is already a risk of disrupting something in the operation of the system, which means only adding problems to yourself.

And what kind of files are there? I mean filenames.

Ilya, defragmentation shouldn’t have been done on an SSD. And if it is set automatically according to the schedule, then it should be turned off altogether.

So that in the future there were no problems (just for any, quite foreseen and quite possible case). I launched chkdsk H: / F / R, which is actually the reason for my descriptions here. 2 hours. “normal flight”. 32%.

“At the request of the workers”. based on my own experience and feelings, I would still risk roughly suggest that for a 3 TB hard drive, freezing for more than 8 hours is already “clinical death” (if not Seagate. there may be a coma and longer), and you need to start resuscitation If the interest is slowly but creeping, I advise you to wait until the end (after a rain on Thursday. maybe), and then start investigating the reasons for the inoperability (and this is it).

Perhaps, like mine, there is bad contact in the connector (or where) when the BIOS sees the hard drive and “does not buzz”, and Windows sees problems but silently slows down. Also, bad or inappropriate cables for SATA (SATA2 instead of SATA3, for example, there are many varieties and “standards” of them now, often of poor quality).
For example, I now have plans to replace the “standard” cables supplied with the motherboard with modern ones when available. over, the “motherboard” is ancient, with a hybrid SATA3 system, which switches modes of operation. “as BIOS and Windows have to the soul”, and cables of the SATA2 standard (workmanship, materials and cost).

After investigating and eliminating the causes, I advise you to be patient and restart CHKDSK X: / F / R. With a similar behavior of the hard drive, errors are more than likely, and if the cause is eliminated, they will be corrected. Then start defragmentation. I’m sure there will be a mess. Better than the standard one, especially if Win10, although some third-party programs offer a “beautiful” arrangement and sort the files on the hard drive, and this makes little sense, but it is more of a decoration. Is it worth building your hard drive in an “Ekibana”?

Judging by the comments, probably many will be interested here, although. offtopic prehistory to the previous topic.
With the next update (up to 2004). “Windows flew into the pipe”, taking with them (after all the standard recovery tools) even the folder “My Documents”.
However, the “Command line” remained, from which I launched the “Kakoyta Commander” previously installed on this disk (I do not remember which one), and downloaded my own, “non-Windows” data to another hard drive (in the current system I have 3 of them).
(Of course, the CIA with BillombezGeitz and their crazy brainchild Microsoft, I don’t trust anything serious, so I didn’t lose any really useful information)
Further. I unformatted (uncovered) my hard drive, and installed a fresh assembly “cleanly”. no problem (as it seemed). Along the way, over the course of several days, gradually, I had already set everything up and almost forgot about what had happened. Confused only by the brakes with additional hard drives in the system
I started defragmentation on the slowest hard drive through the Defraggler program (more clearly than the standard one). The result. hung me up, not a program that

after 3 days, it ended successfully, happily informing me that everything is fine. However. showing at the same time that at the beginning of work 26% were fragmented, and at the end. 40%.
A happy thought, to get into the “hardware” of the computer. came suddenly

An autopsy showed that the cause of all the troubles was poor contact in a bad SATA connector (bad Hitachi team, with their bad plastic), and a bad “regular” (supplied with a bad motherboard, a bad Gigabyte brand) cable, which “dangled in it, like there is something bad in the hole ”, as well as the poor fullness of my wallet, not the moment of purchasing these bad gadgets

For treatment. took out the “guilty” hard drive, and carefully cleaned the connector contacts with a paper knife (rude of course). I cut out a suitable small piece of thin plastic from the “chevota” packaging (

0.15mm thick), slightly bent it, and inserted it directly into the connector, with the expectation “so as not to dangle”. but rather pressed the contacts together.
When loading, it immediately became clear from the speed that basically the problem was solved (a little later I will carry out this prophylaxis with the second hard drive, and the main one is normal and is friends with other brands).
It turns out that Windows is to blame here. only indirectly (not an adequate reaction to, not even the main one, a Venturer, which. “it goes out, then goes out”).

Once again. Hello everyone.
Nothing that in “Task Scheduler / Library / Windows / Chkdsk / ProactiveScan” by default “is”. “Stop a task that takes longer: 3 days.” (Win10 2004 “freshly caught”)?
My task was completed, only slightly, less than the specified time, and at the same time. successfully. And fixed everything.
“It will be a shame if it turns” for 3 days, but 1 hour is not enough for a correct completion
Did I understand correctly that this task is “on demand”. it starts at any start of CHKDSK ?

As far as I know, this task is launched as part of automatic system maintenance, and not at any start of the disk check.

Tell me, what’s the trouble if the check takes a maximum of 1 minute at most? As if it does not check anything, the disk is already 8 years old, and there are clearly problems, but the check seems to fail.

and what kind of check do you run? If chkdsk / f / r. then it should definitely take a long time. If chkdsk / f. it can be fast, if there are no problems with the file system and there are not too many files.

I tried everything. Both, as a result of about a minute checking, for what reason. I don’t know

To be honest, then I don’t know what to assume In the choice of the disc, you could not be mistaken in theory

Recently, the laptop began to freeze and lag, and in the Task Manager in the “Performance” section in the “Disks” section with the description “the load on all physical disks” is shown at startup 100%, it was like this, now it also lags when Windows 8.1 starts (in time of entering the password, etc.), while working on the desktop when you start the task manager, you can see that when you start accounts (loading the desktop) in “Performance” in “Disks”, 100% is shown, then about seconds for 7 is reset to almost 0% of the load on “physical disks”, then again 100% load This lasts 5 minutes at best and the cycle repeats. I tried to clean with CCleaner, JetCleaner, installed and launched Mem Reduct a couple of times did not help, did the “Computer Restore” function (reconfiguring Windows 8.1 with deleting application files, but saving music, videos, documents, etc., did not help Previously, you start and everything works, although before that recently it was that 100% of the disk was at first after loading the desktop, but after 6 seconds it decreased and did not rise anymore. Is it possible to fix this by checking the Chkdsk disk?

Hello.
You can run a check, but it is doubtful that it will fix something.
And observations give an understanding of what specific processes are running loading the disk? (sort by disk column in Task Manager “Processes”)

Michael, did you find the problem? Share, I have the same story, 100% disk utilization on a laptop

And for me, when checking through “chkdsk D: / f / offlinescanandfix” it gives: invalid parameter: / offlinescanandfix
What could be the matter here?

I do not even know. I just checked it. it works (and I copied your text directly from the comment, checked it last on Win 10 Pro).

And I don’t know. I have Win 7, SP 1. On the command “chkdsk D: / f / r /”. the check is carried out, but at the final stage it says something like: “it is impossible to write to the section”

Hello Dmitry,
I ran PowerShell as administrator, then entered Repair-Volume.DriveLetter C and also with the option.OfflineScanAndFix and got the error “Repair-Volume” name is not recognized twice as the name of a cmdlet, function, script file, or executable program. I could not find a solution on the Internet. Can you tell me what it can be?

Hello.
Windows 10? If yes, then I find it difficult to answer. The team must be supported.

Good day
Through chkdsk, I started scanning after 5 minutes and gave errors, please tell me (6e74667363686b2e b67) (6e74667363686b2e 1798)

Hello. I won’t say anything about the error codes. And the text that she reported?

Unfortunately, I don’t remember anymore, I have such a situation, an external hard drive with a wire, I need to transfer 50-100 gigs from it to a PC, I try it with one folder, it misses a lot of files, can you tell me, please, a working method with such a quantity of information. thank
