What Is CHKDSK Command  

CHKDSK, also known as Microsoft Check Disk, is a utility that can be used in almost all Windows versions. The CHKDSK command is used to scan through your entire hard drive to find and fix any errors. For example, when your computer freezes, you cannot access a certain disk due to a corrupted file system, then you can use the CHKDSK commands to check and fix the drive errors.

What Does CHKDSK /F /R /X Mean  

What is CHKDSK /F /R /X? The primary function of CHKDSK /F /R /X is to scan the integrity of the file system and file system metadata on a disk volume and fix any logical file system errors that it finds. Besides, CHKDSK also can be used for detecting bad sectors on the target disk that occur because of physical damage. Then, it automatically fixes these errors as well.

Differences Among CHKDSK /F, CHKDSK /R, and CHKDSK /X

CHKDSK can fix two types of disk errors: logical errors and physical errors. Based on the disk error types, you can use the different CHKDSK commands and switches to fix hard drive errors. CHKDSK /F, CHKDSK /R, and CHKDSK /X are the most commonly used CHKDSK commands. What is the difference between CHKDSK /F /R X?

  • CHKDSK /F: Check for disk errors, not bad sectors. 
  • CHKDSK /R: Locate the bad sectors on the target hard disk and try to recover the readable information from the bad sectors (implies /F).
  • CHKDSK /X: Forces the volume to dismount first, if necessary. It also includes the functionality of /f.

CHKDSK Parameters and Meanings

The syntax of the CHKDSK command is: 

chkdsk volume /f /v /r /x /i /c

If used without parameters, CHKDSK displays only the volume's status and does not fix any errors. If used with the /f, /r, /x, or /b parameters, it fixes errors on the volume. What do the parameters ( /f /r /x... ) mean? Here are some common CHKDSK parameters and their meanings:

Parameters Details of the Parameters
/f Fixes errors on the disk. The disk must be locked. If CHKDSK cannot lock the drive, a message appears that asks you if you want to check the drive the next time you restart the computer.
/r Locates bad sectors and recovers readable information. The disk must be locked. It includes the functionality of /f, with the additional analysis of physical disk errors.
/x Forces the volume to dismount first, if necessary. All open handles to the drive are invalidated. It also includes the functionality of /f.
/b NTFS only. It clears the list of bad clusters on the volume and rescans all allocated and free clusters for errors. It includes the functionality of /r. Use this parameter after imaging a volume to a new hard disk drive.
/v Displays the name of each file in every directory as the disk is checked.
/scan NTFS only. It runs an online scan on the volume.
/i NTFS only. It performs a less vigorous check of index entries, which reduces the amount of time required to run CHKDSK.
/c NTFS only. It does not check cycles within the folder structure, which reduces the amount of time required to run CHKDSK.

CHKDSK /F /R Error TroubleShooting

You may encounter CHKDSK related problems; what to do then? Here are the common issues of CHKDSK errors; read on to figure out the solutions.

Is CHKDSK R safe?

It's safe to run the CHKDSK /R command under normal circumstances as long as you're using the syntax properly. There are different parameters with CHKDSK; you can check the CHKDSK parameters and choose the one that suits your problem to fix disk errors.

How long does chkdsk /f /r take?

It depends.

  • chkdsk -f should take under an hour on that hard drive.
  • chkdsk -r will take some time. It could take over an hour, maybe two, three, or more, depending on your partitioning.

You can interrupt the scan, but not recommended. Canceling or interrupting CHKDSK should not leave the volume any more corrupt than it was before CHKDSK was run. You can start it again, and it will check and repair any remaining corruption on the volume.

What to do when CHKDSK is stuck or frozen?

  • Restart your computer.
  • Press Esc or Enter to stop chkdsk from running.
  • Run the Disk Cleanup utility to clear out junk files.
  • Open an elevated CMD, type sfc /scannow, and press Enter to run the System File Checker. 
  • Restart and exit chkdsk again during the startup by pressing Esc or Enter.
  • Open CMD as admin, type Dism /Online /Cleanup-Image /RestoreHealth, and press Enter to repair the Windows image.
  • Run CHKDSK again.

The scan should be able to run to completion this time.
