That's worth a though, I'll check. I put a 500gb hdd in a week ago, now when I run a check it says missing files, then today while I'm in word Program a note pops up c:\ is almost full del files. What 80gb partition, and 1.71gb used. so I check other partitions and one 150gb is half full as well. It's a new Western Digital with 16mb cashe file and a special fast search built in. I wonder if Win xp can run it. I don't want to buy another now. WD said to format C:\ and try again, but why is the other drive 1/2 full to. Anti-virus is up to date and working, ran it full-scan. Going bald fast. Brian
