My Vista defrag has been going for 48 hours. I signed in as administrator first then tried your suggestion, but it says now. "A defragmentation or volme shrink operation is already in progress. only one of these operations can run at a time. Wait until
the current rocess finishes and then try again."
Which did help, because i can't see if the defrag is actually happening. So I guess its still going on. But do you have any clues as to why the length of time? or some other way to monitor it?
