My computer really struggles with defrag - I usually have to do it in safe mode from bios boot-up. Sometimes it works, other times it doesn't. If I try defrag from windows ME it will just keep restarting itself untill it gives out an error message. Scandisk works fine but again I usually get the restart error. Last time PC got a scandisk and defrag was last month, and I've only just stuck in the PIII 700! I was struggling with a PII 333! I've got 2149 tracks on PC, some of the tracks are 60+ minutes, I should tidy it up a bit as some of the files are talking books for my kids, I did have the intention of setting up the minidisc in their rooms for night time bed stories but I find reading to them to be more fun. Again, thanks for all the help!
