No Errors but can't Defrag

[richy]

I'm trying to Defrag my machine as its being a bit slow, but I keep getting an error saying that there are errors on my drive and that I should run ScanDisk. I do this, but it tells me everytime that there are no errors. Can anybody please help me.
Thanks very much.

Try Scandisk for low-level errors (thorough scan).

Defrag has found a corrupted file when it tried the MoveFile api.
It couldn't actually read the physical data. High-level Scandisk runs just check to see that files are where they are supposed to be, the size they are supposed to be --not whether each file can be completely read successfully. Low-Level scan does that.

If ever I do a scan disk I always use the Thorough rather than the Standard check so its not that thats the problem. This is what is confusing me is that the options are all set to the most thorough.
Any more ideas anyone? Could it be an actual hardware problem?

go into safe mode and try it.

[richy]

That worked. Thanks jim and scoutt for your help.

I didn't think that would work. Any ideas why? Maybe something was running in Normal mode interfering with the defrag?

[richy]

I did close most of the programs I knew that were running, e.g. Sonique, ICQ and all them, but there might've been something else that was stopping it.

Virsus Checker maybe?

[richy]

I do have Innoculate installed which I didn't close, so yeah that could've been it. I'll have to try it a bit later and tell you what happens for future reference.

[richy]

I've just closed Innoculate and run it, and it started Defragging fine. So thats the answer.

Hurrah! Virus Checkers should stop when your defragging, or at least give you the option to stop when certain apps are active.
