A new critical flaw in Windows 10 version 2004 and version 20H2 is crashing some computers when users run chkdsk command. For that unaware, chkdsk, also known as Check Disk utility, allows you to scan through your entire hard drive to find and fix problems.
Chkdsk is a command-line tool and it doesn’t come with a graphical user interface, but it can really help prevent bigger problems and loss of data in the long run. When you run into issues with Windows 10, Chkdsk is one of the most effective ways to address problems, but it depends on how it’s run.
Windows 10’s latest update, which was supposed to fix some big issues, seems to be causing some serious problems. According to user reports, Chkdsk c: /f command is broken after the December 2020 update and it could crash your device with Blue Screen of Death error.
This c: /f chkdsk command option is designed to fix any errors found on the disk, but it’s apparently causing more problems for some people. Under certain circumstances, running chkdsk command on the partition drive (SSD) could crash your device with NTFS FILE SYSTEM stop code.
The good news is that the problem is rare and it was flagged by Insiders in August, which means it might have ended up getting backported to Windows 10 October 2020 Update/May 2020 Update production builds.
“I was doing routine maintenance on my PC, I ran chkdsk c: /f from an elevated PowerShell console and restarted my PC. It seemed to work normally, but after the chkdsk ran, my PC restarted again, then tried to run another chkdsk and failed, then tried to diagnose startup problems and failed and then started the recovery screen,” one user noted in the Feedback Hub.
In the meantime, the simplest solution is to avoid unnecessary running the chkdsk command. In any case, you can always reboot the system to return to normal functioning if a Blue Screen is encountered.
