    I did a Google search and the explanations were esoteric to me.

    chkdsk c: /F

    It might be an error on the drive. We suggests that you follow the troubleshooting steps below:

    • Run Disk Cleanup utility to clear your junk files.
    • Open an elevated CMD type sfc /scannow and hit Enter to run the System File Checker.
    • Once the scan is completed, restart your computer. Remember to exit ChkDsk
      during boot.
    • Next, again open CMD as admin type
      Dism /Online /Cleanup-Image /RestoreHealth
      and hit Enter to repair the Windows image.
    • Now see if ChkDsk able to complete the scan.

    Note: Before doing the steps, make sure you save a back up of your files.

    Let us know how it goes.

    chkdsk c: /F

    We appreciate the response. I'm referring to Check Disk (chkdsk) utility tool. If you haven't tried yet, we suggest that you run a chkdsk by:

    • Press Windows Key + X button to bring up the power user menu.
    • In the power user menu, select the Command Prompt (Admin) option.Click Yes when you are presented with a UAC window requesting permission to launch the Command Prompt as Administrator.
    • In the new Command Prompt window, type chkdsk E: /f /r /x. Here you should replace E with your drive letter.
    This option will run chkdsk to check and repair disk errors in Windows 10. The “/f” parameter tells CHKDSK to fix any errors it finds; “/r” tells it to locate the bad sectors on the drive and recover readable information; “/x” forces the drive to dismount
    before the process starts.

    Keep us updated with the result.

    What does "chkdsk c: /b" exactly do?

    What CHKDSK exactly logging and 'flashing' messages on prompt?


    It is an incorrect conclusion TBH, chkdsk will say if it found a bad sector after a stage is done.
    So, there are 5 stages,
    1. file structure scan,
    2. file name linkage scan,
    3. security descriptors scan,
    4. user data scan,
    5. free space scan
    if in stage 4 a single sector is found then chkdsk will mention that after the scan of stage 4 is finished.

    The conclusion is that it is not known if chkdsk found any bad sectors.
