Windows – How to cancel Windows 8 drive repair

This condition is what Windows refers to as "setting the dirty bit" and you have to unset that bit. If the dirty bit is set,then autochk performs an immediate chkdsk /f on that volume. This is usually caused by an unusual shutdown or a power loss during a read/write operation.

This could possibly fix it:

Click Start and type cmd in the search programs and files dialog box. Then type fsutil dirty query c:.

This query will return an answer if your drive is dirty or not. Most likely its dirty

Next, type chkntfs /x c:.

The x tells Windows to not check that particular drive on the next reboot. At this point reboot your computer, it should not perform a chkdsk on startup and take you directly to Windows.

When you are back in Windows you want to do a manual check disk on the c drive, to do this:

Click Start and type cmd in the search programs and files dialog box. Now type chkdsk /f /r c:

This should take you through 5 stages of the scan and will unset that dirty bit.Since this will have to run a checkdisk on your C drive it will ask you to run it on your next restart.

Finally, type fsutil dirty query c:

This will confirm that the dirty bit is not set on that drive. Hopefully this resolves your problem.

There is no safe way to terminate a chkdsk in progress. Even if you do, it will run at the next reboot since it sets the dirty bit when you run the command. There is no good reason to cancel chkdsk this way, unless the PC is locked up during a chkdsk.
