Agree with Stuxnet. I'd try reinstalling it and giving it a few tries at booting. If it doesn't cooperate go ahead and run wdidle3.exe and either set the timeout to 300 seconds (5 minutes) or disable it and see if that doesn't do it. FWIW the Intellipark setting wouldn't be affected one way or the other by the IC (or any) image or vice versa. However there still may be an issue with some of these drives.
