Hi there, I have the "cannot move files" error message, and after 10hours of idefrag booted from a CD, it still says the same message. So i assume i have to format and reinstall OSX? I can backup using time machine to an exernal drive, thats no probs, but when i reinstall OSX i dont have my snowleopard disks to hand, would that be a problem, or would it copy from timemachine? (its at a parents house and i wont be able to get it till next week). also any tips for doing it this way? just need xp installed for some games.
