you got it.... that may very well be your problem. Now that the sectors are marked, windows will not try to use them again..(for virtual memory, and stuff. That happened to a guy at work the other day. His machine was locking up, and he had a pile of files turn into garbage. I asked him over and over if he had scanned his disk, and he said yes. I scanned it, and it mark 1 bad cluster. It was enough to really throw windows off, and garbage a bunch of his files.....
