bring up a command prompt by typing in CMD click on OK and type fsutil dirty query d:
This queries the drive, and more than likely it will tell you that it is dirty.
Next, type CHKNTFS /X D:
The X tells Windows to NOT check that particular drive on the next reboot. At this time, manually reboot your computer, it should not do a Chkdsk and take you directly to Windows.

Once Windows has fully loaded, bring up another CMD prompt, now you want to do a Chkdsk manually by typing Chkdsk /f /r d:. This should take you through 5 stages of the scan and will unset that dirty bit. Finally, type fsutil dirty query d: and Windows will confirm that the dirty bit is not set on that drive.
