Disk Error Checking: How to run CHKDSK in Windows 10

Users of Windows 10/8 may have noticed that Disk Error Checking is a bit different from the earlier versions of Windows. Checking your hard disk, every once in a while for errors – usually caused due to improper or sudden shutdowns, corrupted software, metadata corruption, etc., – in Windows 7 and earlier is always a good practice as this can help solve some computer problems and improve the performance of your Windows computer.

Disk Error Checking in Windows 10

In Windows 8, Microsoft has redesigned chkdsk utility – the tool for detecting and fixing disk corruption. In Windows 8, Microsoft introduced a file system called ReFS, which does not require an offline chkdsk to repair corruptions – as it follows a different model for resiliency and hence does not need to run the traditional chkdsk utility.

The disk is periodically checked for file system errors, bad sectors, lost clusters, etc., during Automatic Maintenance and you now no longer need to really go and run it. In fact, Windows 8 now even exposes the state of the file-system and disk via the Action Center or under the Drive properties in File Explorer. If potential errors are found, you will be informed about it. You can continue to use the computer, while the scan is carried out in the background. If errors are found, you may be prompted via a notification to restart your computer.

Windows found errors on this drive that need to be repaired

At times you may see a message – Windows found errors on this drive that need to be repaired. If you see it, you may want to manually run a scan. Earlier you had to schedule Disk Error Checking for the system drive and for drives which had files or processes or folders opened. In Windows 8, error checking starts right away, even on the system drive – and it longer needs to be scheduled at start-up. Only if some errors are found, will you have to restart to let Windows 8 fix the errors.

How to run CHKDSK in Windows 10

To begin the scan, right-click on the Drive which you wish to check and select Properties. Next, click on Tools tab and under Error-checking, click on the Check button.  This option will check the drive for file system errors.

If the system detects that there are errors, you will be asked to check the disk. If no errors are found, you will see a message – You don’t need to scan this drive. You can, nevertheless, choose to check the drive. Click on Scan drive to do so.

The scanning starts. I found that the process ran quite fast and the scanning was over in less than 5 minutes.

On completion, Windows will display a message. If no errors are found it will say so.

If errors are found, you will see the following message:

Restart your computer to repair the file system. You can restart right away or schedule the error fixing on next restart.

When I clicked on Show Details, the Event Viewer sprang to life, showing me the relevant log.

In Windows 8/10, Microsoft has made the Disk Error detection and correction of file system errors less intrusive so that users can carry on working on their computers without worrying about such error.

To run Check Disk on your System Drive (C), using the command line, type the following and hit Enter:

chkdsk /f C:

If required, restart your computer.

    This new Error Correction tool in Windows 8 sounds great. This kind of utility would have been extremely useful with the Vista and 7 OS’s.

    what happens when check disc deletes files, I need to get them back where do they go where do I look

  12. Disk Error Checking will not delete files. If the disk was already corrupted, then you may have lost those files. But you may try some of these to recover files: https://www.thewindowsclub.com/7-free-data-recovery-software-to-recover-deleted-files-in-windows-7

    In Windows 10 I’ve found the following to be better:
    chkdsk C: /scan /offlinescanandfix /R
    /R is probably redundant… but it gets me what I want.
    This schedules the scan to be done with file system offline at the next reboot.

    I don’t see any process to chkdisk for windows 10.

    “In Windows 8, Microsoft introduced a file system called ReFS, which does not require an offline chkdsk to repair corruptions – as it follows a different model for resiliency and hence does not need to run the traditional chkdsk utility.”

    Windows 8 and 10 still use NTFS by default. You can right click your drive and see what it says for “File system.”

    But self-healing NTFS was introduced in Windows Vista and it fixes file system errors on the fly and no longer requires offline chkdsk.

    what to do when the repair fails and shows a dialog to rescan and repair again but nothing happens

  17. vamsidhar

    Why my disk utilization is 100 on Windows 10 always?

  18. mockmook

    How thorough is the Windows 8 CHKDSK?

    Does it write data to the all the sectors and make sure that they read back properly?
