Trying to defrag my "C" drive (got two hard drives, C & D, plus cd-rom & floppy)
Turned off screensaver & task scheduler, disabled firewall & anti-virus & ensured broadband connection stopped.
Everytime it gets to 10% it says "drive data changed" and starts again.
Thought it might be me, so tried to de-frag'd the "D" drive - did so with no problems.
What haven't I turned off/disabled on "C" that needs doing?
Ta!

you will hear it spinning up the empty floppy days later trying to find the document.
