Did a defrag on my 80GB NTFS volume and immediately after....the whole thing died a horrible death. Over 5000 unreadable file segments...prob more but I hit the big X to shut the damn thing down because it made me sick.

What would cause this given that my drive seems ok now? A reformat fixed it. Why did I have to lose 65GB of precious precious precious (they were really precious) files?

Anyone else have probs with defrag? Never seen this happen before.

Weird too because I defragged C and it was ok. But D: was not readable and was causing major lockups. Windows shell does not respond to drive/file-system failures very well.
