Run a disk check for errors. How to run Chkdsk to fix disk errors? Command line recovery

Chkdsk is utility programintended for hard check  disk for errors and their correction. The program is used in cases where the system displays messages about various errors related to the hard disk, files, drivers, etc.

In order to run this utility in Windows 8, you need to do the following:

One of them is the basic version, which is used by most of us, and the other is the command line version, which has more features. Here you have options for automatically fixing file system errors and scanning and trying to recover bad sectors.

To use the command line check version, open the option. You can also use the following options at the end of the command to specialize your operations. Also cancels all open file descriptors. This documentation is archived and not supported.

Step 1. If you are working with the console from a user account, then when you enter the CHKDSK command, this window will appear:

The easiest way out is to switch to account admin  and run the console as administrator. We go to the Start menu and select a user with administrator rights:

I want to warn you right now that disabling CHKDSK autorun deprives you of control over the integrity of your file system, which can lead to consequences!

Checks the metadata of the file system and volume file system for logical and physical errors. The status report displays errors detected in the file system. This can happen if open files  not yet written to the file allocation table. Do you want to plan this volume for verification the next time you start the system? . Please note: many parameters imply other parameters. By the way, you need to put a forward slash before this parameter, not a dash.


We click on this application with the right mouse button. An action panel will appear below: select "Run as administrator":


We will launch the console as administrator:


Only after use hard drives  for 5 years, it occurred to me that disk storage could cause problems. And he did not let me boot into safe mode. In the "Power Users" menu, select the "Command Prompt" option. If any data is available, data may be lost. Creates and displays a status report for a disk based on the file system.

You can use wildcards to specify multiple files. If necessary, pushes the volume, if necessary. Changes the size of the log file to the size you specify. In this article we will talk about Chkdsk and its use. You can run a disk check if you think the file system is damaged when updating your system. Here are some of the important switches.

Here we need to enter the chkdsk command and press the Enter key, after which the disk check will start.

If you do not have the opportunity to do this, or you do not know the passwords from other people's records, you will have to check each logical drive  separately. To do this, go to "My Computer" and select the desired drive:

Select "Properties" in the drop-down menu. If the files are open, the following error message appears. If no size is specified, the current size is displayed. Then all open volume descriptors will be invalid. Displays help on the command line.

Capital letters are used below for emphasis but are not required. Additional Information  Available to install and use the command line recovery console. And only then can you defragment. Then, bad sectors are also detected, and the data in it is restored as much as possible.

We put all the checkmarks and click "Launch":

We will be asked to reboot the system, after which this disk will be checked.

Step 2. If you know for sure that you are working under an administrator account, then simply press the key combination Win + R on the keyboard. In the window that appears, type the command “cmd” without quotes.



Step 2  Now write the command “chkdsk” without quotes, as shown in the screenshot. The program will search for errors (without fixing them). How to fix found errors is described below.



Step 3  Add the /? Flag to the command, as shown in the screenshot. All parameters will be displayed. chkdsk utilities. Select an option. In particular, to correct errors, use the / F option.

For security reasons, you should also check the hard drive with a service tool from the manufacturer. hard drive. Most manufacturers offer such tools for free on their home page. Please let us know how you like our contribution. To do this, click on the stars shown below.

This is less than the purchase price than the cost of the data stored on it. A system crash does not always come suddenly. Many cancellations can be canceled by various crashes or error messages. But is defragmentation necessary during technological progress?

How long does it take Windows to boot?  Sometimes it seems like it takes an eternity. There are several methods to speed up system loading, but perhaps the problem is that your computer performs the CHKDSK function at each boot.

The hard drive cannot work as usual for various reasons. Just like universal tools and techniques for hard recovery  drives. As mentioned above, it is a system tool for checking the structure of files and directories to ensure consistency and recovery of damaged data structures, if necessary.

Invalid sectors. Lost assignment units. Cross-references. Catalog errors. Double-click the “Computer” icon on the desktop. . In the "Computer" window, right-click on any data medium and select "Properties" in the context menu. In the "Properties" window of the selected storage medium, select the "Tools" tab. The media check window opens with two possible settings.

Did you notice the filling bar while you were waiting? Does she appear often? Have you ever wanted to know what it is, what is happening, and does Windows really need to do this? Read this article and we will answer all these questions together.

If you are not sure which drive you have installed, check if it is a solid state drive ( SSD) or hard drive (HDD) If your computer has an SSD, you can still use Check Disk, but you do not have to run a check with the flag / r. There are some differences between SSD and HDD, in particular, SSD does not have moving parts.

Chkdsk Check for Disk Errors

The default value is indicated in the screenshot. If you want to check the hard drive for bad sectors, you must also set the second tick. You may need to start the computer in command line mode. Here is an example call. The following note applies to all hard disk analysis tools. Make sure your hard drive should not be put back into operation. Any further operation may mean a certain end of your hard drive, as well as further data loss.


The SSD does not include a physical disk, so it does not need to be verified chkdsk team  c: / r. However, Windows uses the same file system on both the SSD and the HDD, so you can fix file system errors when help chkdsk  c: / f. Other than this, Check Disk is not necessary.

In addition, the analysis tool presents an additional heavy load on your hard drive, which should be avoided at all costs. In this case, you should have one. Even today it is an effective tool.

You can cancel the volume check, but it is strongly recommended that you continue the process. To skip the test, press for 10 seconds. . The following are some common causes of messages. Select the scenario that applies to your case.

On Windows 7 and earlier, verification may take some time. Maybe an hour, and sometimes an entire day or more, so make sure you have some free time. Do not interrupt the operation of Check Disk after it has begun.

To start the utility, click on the Start button. In the search bar, enter " command line". It should appear in the search results. Right-click on the command line and select "".

Since the contents of the storage device have changed after the computer enters sleep mode, the information from this computer will correspond to the volumes on the volume. Therefore, corrupted data or inconsistencies occur after the computer starts. Failed to read selected boot disk. Check the startup path and hardware on disk.

Reinstall the instance of the above file. You may also notice one or more of the following types of behavior. This can happen if one or more of the following conditions is true. To resolve this issue, use one of the following methods.

After the command prompt window appears on the screen, enter the command

and press the button Enter. Thanks to the / r flag, the program will try to recover information from the damaged sectors, as well as fix all errors on the disk, so you do not need the / f flag.

Command line recovery

Restart your computer and select the first item in the Start menu after completing the previous steps. We reported various improvements in the kernel, network, and file system of the operating system. A look at the actual use of Chkdsk showed that damage is extremely rare, but the use of Chkdsk is not. We are working to reduce the manual execution of data transfer tools. However, we know that many people prefer to run these tools manually.

How to force remove restore CHKDSK from startup?

Today, as disk throughput increases and systems become more common across multiple volumes, we wanted to improve our support program. Kieran Bangalore, program manager from our team for the core system, wrote this post. - Stephen. Today, there are a number of reasons for data corruption, even if they are extremely rare.

The command line will tell you that it cannot execute this action, because indicated volume  now in use. She then asks if you want to schedule a volume check for the next boot. Enter Y  and press Enterto schedule the launch of Check Disk with the error correction option.


File System State Redesign

In this model, the volume was turned off during the period when the damage to the file system was repaired and the system returned to the error-free state. Downtime was directly related to the number of files in the volume. FROM large servers  storage takes even more time. Our customers have set three important file system health requirements.

Check if it helped

Downtime caused by file system corruption may not occur in permanently available configurations and should be zero for all other configurations. The user or administrator should always receive information about the state of the file system. The user or administrator should regularly be able to independently restore their file system if damage has occurred. The new project divides the process into the following steps to provide a coordinated, fast and automatic solution to the problem of damage.

Restart your computer and wait for the utility to complete its work. After the check is completed, all errors must be fixed, and Check Disk will no longer start at boot, unless, of course, there are other problems.

Windows 8 deals with such problems in a more efficient way. The file system constantly checks itself for errors. Errors that do not require a disk shutdown are fixed immediately. Correction of other errors, which can be performed only at boot, is planned for the next system startup.

Important design changes to improve accessibility

You can also introduce new definitions of verbs to diagnose future problems. Online check: some damage is temporary due to memory problems and does not have to be the result of real corruption on the storage medium. It is launched by the file system driver and checks if there is real damage on the disk before transferring the file system to the health model for verification. This new service runs in the background and does not affect the normal operation of the system. It remains passive until it is started by the file system driver to check for corruption. Online identification and logging: when a problem is detected, an online scan of the file system is started, which is performed as a maintenance task in the file system. This scan can be performed as a background job, while other programs continue to run in the foreground. As the file system is scanned, all detected problems are registered for subsequent correction. Accurate and quick correction. At the request of a user or administrator, the volume can be muted in offline, and the recorded losses from the previous step can be eliminated.

New health model for file systems

  • This repair can be done while working online.
  • Better management.
  • Service center.
  • Drive status is displayed as “Drive Status” in the Service Center.
  • It may be useful when remote control  file system state.
In the new health model, the state of the file system changes between four states.

Since the system needs to fix only those errors that require a disk shutdown, Check Disk does its job in a few seconds or minutes. To do this, click Start. Enter “ cmd»To the search bar of programs and files. The topmost search result will be cmd.exe. Right-click on the line and select “ Run as administrator».

To make sure that all other problems are found and resolved, first run a disk check by running the command

chkdsk C: / scan

and by pressing Enter. During the scan, the utility will fix everything that does not require a disk disconnect. After verification is complete, enter the command

chkdsk C: / spotfix

and press Enter. You will see a text saying that this volume is busy with another process. The command line will then ask if you want to schedule a disk check for the next system boot. Enter Y  and press Enterto schedule Check Disk to run. Now restart your computer.

This time, Check Disk will start and fix all errors detected during the scan. And since the utility only has to fix errors that require a disk shutdown, it will take only a few seconds or minutes.


Now with your file system  it should be all right. Check Disk will no longer start when you turn on the computer, if there are no other problems.

Check if it helped

After completing the work of Check Disk, there is only one way to check whether the utility has completed its task - restarting the computer. Let's hope that the program will no longer start, and you can continue your work. If Check Disk continues to run, you may have more serious problems with the file system, or errors related to the registry or operating system. You should consider a system recovery option or full reinstalling windows. Maybe it's time to change hDD. Of course, this is an extreme measure, but it definitely solved your problems.
