Rich,
Try running defrag and scandisk from safe mode. Your problems could be
due to either your AV or firewall application writing logs to the
partition you are defragging.

Hi, Mike:
I found that I had to defrag (ScanDefrag in my case) in safe mode AND turn
off my DSL modem. Even in safe mode, I was getting a few "restarting --
drive's contents have changed" episodes. Can't imagine what would be running
in safe mode, but disabling the modem seemed to do the trick.
