Chkdsk (Chkdsk.exe) is a command line utility on Windows systems that checks disk volumes for file system problems and errors. This tool can also try to fix any errors it finds. For example, chkdsk can fix problems related to bad sectors, orphaned clusters, and orphaned files and directories. By the way, I recently wrote about the features of working with c . However, the automatic check of the file system by the chkdsk utility, when the PC is not rebooted correctly, annoys some users. And in principle, such a check can be disabled (although it is not recommended - because you lose control over the integrity of your file system).

To disable automatic check disk at booting Windows, go to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager

In the right pane, double-click on the key BootExecute. The default value of this key is autocheck autochk *

* means that each disk is checked for consistency (integrity, consistency). Just add the "/K:C" parameter before the *. The /K option disables automatic checking of the C: drive when Windows boots. So, the final value of the BootExecute registry key should look like this:

autocheck autochk /k:C *

If you want to disable scanning on other drives (for example, on drives C: and D:), use the following key:

autocheck autochk /k:C /k:D *

If you want to change everything back, just replace the parameter value with:

autocheck autochk *

If you do not find the specified key in the registry, you can disable disk check at boot using the utility chkntfs(key /x). To do this, open a command prompt with administrator rights and type the command:

chkntfs /x d:e:

Then restart your PC. The specified command will exclude drives D: and E: from the automatic disk check procedure at boot. If you need to exclude other drives, simply modify the command to include the appropriate drive name.

The chkntfs /d command returns the original settings (all system disks are checked at boot, and Chkdsk is run only on disks with errors).

In any case, if you disable disk scanning at boot, you must periodically check them manually. You can check the disk status this way:

Message F: is not dirty indicates that the disk has no errors and does not need to be checked.

This article will help you understand and fix problems on your PC. First you need to figure out why you should check your computer for errors. As a rule, you can observe a situation where the computer begins to reboot, while making some sounds such as tapping.

Also, the PC may reboot several times a day, and even when the computer is turned on, the startup may be interrupted by the so-called screen of death. The screen of death refers to a blue screen with white text. It is to prevent such problems that diagnostics need to be carried out.

Using a standard Windows utility

Using the CHKDSK command

1. Click “Start”, select “All Programs”, click “Accessories” and launch the “Command Line” utility;
2. For example, we want to test our disk (D:), then we should specify the command “chkdsk /r” in the window and click on Enter.

This Windows operating system command makes it possible to diagnose the HDD and identify the presence of errors. It will also notify you of any problems found.

CHKDSK Command Syntax and Options

The CHKDSK command [volume:[[path]filename]] ] begins the actual diagnostics of the hard drive in Windows. However, you should not enter command line square brackets.

Volume - indicates the disk on which the check or any other operation will be performed.

Path, file name - lists the name of the object or objects that will be worked on. Applies only to FAT/FAT32 file system;

Description of other parameters:

• /F - completely corrects all found problems;
• /V - command for the NTFS file system, which shows what the cause of the problem was;
• /R - execution searches and restores incorrect information;
• /X - if there is such a need, it completely disconnects the disk from the system for a deeper and more thorough scan. Typically used with the /F command;
• /I - less detailed diagnostics of disk elements. Performs a so-called “quick check”;
• /C - makes it possible to skip checking cycles inside the folder structure; the check is also fast, but not deep;
• /L:size - allows you to change the size of the log file to the specified size (in kilobytes) during the scan. In the event of an abnormal shutdown during testing, a log file is used;
• /B - the ability to re-evaluate damaged clusters on the disk (only if the /R parameter is present).

The process of identifying hard drive errors in Windows may take time depending on the speed of your computer and the presence of errors on the drive.

Hello friends! Well, it’s time to publish another useful lesson. Right here and now I will tell you about checking the disk, or rather, about how to disable automatic disk check, which starts when the operating system boots.

You may be wondering why you should do this; it takes a few minutes, and they are not checked often. If you look at all this on the one hand, then everything is so, but on the other hand, this is not always the case. I recently came across two computers in which, for unknown reasons, a disk check (chkdsk) appeared every time the PC was booted.

No matter how many times I waited for the test to finish, after the next reboot of the PC, the image with the start of the test of one of the sections appeared on the screen again. After several hours of searching for the problem, nothing brought the desired result, not even me, but the test showed that everything was fine with the hard one. So after this I I decided to just disable automatic disk check, so that it does not bother the user who contacts me.

I would like to note that sometimes the constant launch of disk check is associated with a flash drive inserted into the computer. Therefore, first of all, make sure that you do not have any external drive inserted into your computer.

If it’s not a flash drive, then let’s figure out how to disable automatic disk check (chkdsk) and get rid of wasting time when booting the system.

Disable automatic disk check or chkdsk

As I mentioned in most previous articles, many system-related settings can be changed in the system registry, which we will now have to use.

As usual to get started.

Let's take this path:

Now we turn to the right window where we find the key with the name “ BootExecute" You can immediately see that the opposite value is set to “ autocheck autochk *", where the first two words trigger a disk check, and " * " means that all disks installed in the computer will be checked.

By changing this value, we get what we want. To do this, simply double-click on “ BootExecute"And there in the line that appears, before the asterisk, write in the following letters: " /K:C" Just " /K"and is responsible for disabling automatic disk check at the moment Windows startup. Well, as you understand, the second half of the value is the drive letter that will be ignored. For clear example I’ll show you what the “BootExecute” value should look like:

autocheck autochk /K:C *

To disable other drives, such as D, you simply need to change only the letter. If you need to disable automatic checking on both disks, then the required value should look like this:

autocheck autochk /K:C /K:D *

If you suddenly decide to return to your previous settings, then simply change the value to the standard value that was originally set:

autocheck autochk *

After that, my problems were solved, the disk was no longer checked, and the users were satisfied. Therefore, by disabling automatic disk check when Windows boots, thus, perhaps even without fully understanding the essence of the problem, you can get rid of the long boot time of your system.

CHKDSK is short for check disk, which roughly translates to “disk check.” This is a standard application for the Windows operating system that checks HDD for file system errors. Moreover, the application can fix file system errors.

Utility built into operating system, so you won’t have to look for it for long. So, attention.

Open “Computer” and select the hard drive that interests us. We right-click on it, after which a menu appears. Select “Properties” from the menu.

The disk properties window will appear in front of you. Select the "Service" Tab and click "Run Check".

A small window will appear. In it you need to check the boxes (or check them as you wish) next to the items “Automatically correct system errors” and “Scan and repair bad sectors”. Next, click the “Launch” button.

If it is not system disk, the check will be launched, which is what you will actually see.

If the disk is a system one, that is, it is used in this moment, you will be prompted to check it the next time you start your computer. Click OK or, in my case, “Schedule Check Disk.” In this case, the check will be performed the next time you restart the computer.

How to run CHKDSK from the command line?

There is nothing complicated here. Click “Start” and in the “Search programs and files” line write the word cmd. A shortcut will appear at the top of the window. Right-click on it and select “Run as administrator.”

After you have launched the command prompt as an administrator, enter the command chkdsk c: /f, where c is the drive letter that needs checking, and /f is a parameter that specifies how errors on the drive will be corrected. Press Enter.

If the drive is a system drive, you will receive an error that the drive cannot be locked and the CHKDSK command cannot be executed. You will be prompted to check the volume upon reboot. Type Y and press Enter if you agree, or N and press Enter if you do not want to check on reboot.

If the disk is not a system one, the application will perform a scan and all scan results will be displayed on the command line. By the way, the process of finding errors and correcting them can take from several minutes to several hours, depending on the configuration of the disk and system.
