If you suspect your Windows 8 system may have a corrupted hard drive, then you might be tempted to use the old chkdsk /f command. This does still work, but it’s horribly slow, and won’t do anything at all until you reboot. What’s more, it may no longer be necessary now.

Windows 8 now regularly runs chkdsk in the background, looking for problems, and recording them. And then, when run at boot time, it doesn’t have to scan every single sector of your hard drive. It just fixes the known problems, usually in a few seconds.

The first lesson here is that you probably won’t have to use chkdsk any more.

But if you want to try it anyway, don’t use chkdsk /f first. Enter chkdsk /spotfix instead, agree to run a check when you next reboot, then restart your PC and any fixes will be applied, much more quickly.

While this works most of the time, there are no guarantees. If you’re out of other options then you can still try chkdsk /f later.
