Disk Defragmenter Crashed - is system ok?

January 22, 2010 at 19:39:57
Specs: Windows XP, AMD Athalon XP
I ran Disk Defragmenter on my C Drive and at about 54% the program locked up and I received the message that Disk Defragmenter encountered a problem and had to close. I closed and reopened defragmenter and ran defragment on the C drive again and it finished.

Since defragmenter crashed in the middle before it could finish on the C drive, will my system be unstable now? Anyone heard of this?

It sure doesn't sound good. I would run the manufacters hard disk diagnostics to first rule that out... run it in dos mode.

What I really want to know is: could having the defragmenter crash in the middle of the defrag on the C Drive have corrupted my C Drive or screwed up the data on it?

back in the day, ( when I had Windows ME and a system with only 64mb ram) windows defrag frequently encountered such errors and interruptions and in the end I decided that the only way to get it to run properly was in safemode. If your system has too many running processes and a limited amount of ram then it will start to use pagefile while running defrag. Pagefile is a section of harddrive used as temporary storage when ram is unavailable. Defrag detects changes to the harddrive that it did not initiate so it says "oops I cannot continue"

If you were able to complete a subsequent defrag I would not be too concerned but as a precaution I suggest run chkdisk
and in future defrag in safemode.

As Richard59 stated since you where able to complete a defrag after the prior one failed you are most likley OK ! I had a simular exprience as yours when defraging my H.D. and the amount that H.D was fragemented imediatly after the failed defrag was way to high ,however running the defrag utility again made the % of files fragemented in the correct range of a normal defragemented H.D. I believe you are OK seeing that you could run and complete a defrag right after the failed one !
