This, as a result, will also resolve the said issue in no time. Now for doing so, follow the steps given below:
NOTE: To maximize the chances of running an effective CHKDSK scan, it is recommended to do the same from an elevated Command Prompt.
- Firstly, press Windows + X and click on Command Prompt (Admin) from the context menu. In case you come across the UAC (User Account Control) prompt, then click on Yes.

NOTE: Make sure you specify the parameters; else, CHKDSK will only scan the selected drive and present you with a summary of its findings. In case you are confused about the parameters, you can choose the following:
/f – Tells CHKDSK to fix any and all errors that it finds
/r – Tells CHKDSK to locate bad sectors on the drive and try to recover any and all readable information from them
/x – Tells CHKDSK to forcefully dismount the selected drive before scanning it
- However, the final command you will type in the Command Prompt window must present like this:
chkdsk C: /f (if you want CHKDSK to scan your computer’s C drive for errors and try to fix any that it finds)
or
chkdsk D: /f /x (if you want CHKDSK to dismount your computer’s D drive and then scan it for errors and fix any that it finds).
- Not let it complete the scanning process on its own.
