Trouble running disk scan

I'm running ME, and can't seem to get a thorough disk scan to run to completion. Something keeps interrupting the process. I've been doing this after booting in safe mode (as suggested by someone on this forum), but I'm still getting the interruptions. Only thing running in the background (only thing that shows up when I do ctrl-alt-del) is Explorer, which has to be running. I would appreciate any/all suggestions.
Thanks

 

Try turning off your screen saver also.

 

Screen saver doesn't work when you boot in safe mode; I've been turning the monitor off once the disk scan kicks off.

 

Something really simple to do is to insert your system disk into your floppy drive and restart the computer. Select "Start computer with cd-rom support" (you don't have to have the cd in though) and wait until the command prompt comes up. type in "C:" and press enter. Then type in "scandisk c:" (I don't remember if you have to put a space between scan and disk) and press enter. Let it run, and there should be no problems!
