What OS are you using? In XP I know you need to set the HD to run a scan before next startup. Defrag should work no matter if your in your OS or not. In earlier editions you should be able to start in safe or dos mode and then try running it. Make a windows startup disk and see if that works.

You may also want to run a Virus scan to rule that out as a possibility: http://housecall.trendmicro.com/

What are you using to scan the drive?
