How to run an offline chkdsk scan on Windows 8

Problem: If you issue the "chkdsk c: /f" command in order to run an offline chkdsk scan on Windows 8, it will accept the command, but when you reboot the computer, chkdsk will not run.

Because of ReFS, you should not need to run an offline chkdsk scan anyway. However, there are times we simply just need to run it to rule out file and file system corruption.

Solution: Disable Fast Startup: Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable > Disable Turn on fast startup (recommended) > Save changes.

Issue the "chkdsk ,drive_letter>: /f" command and reboot. You should be able to see the offline chkdsk scan progress messages below the Windows (or computer manufacturer) logo while the computer is booting up.

Fast Startup does allow for a faster bootup, so you really should turn it back on when finished with the chkdsk scans :)
