"If you can, get a new drive, stick it in, save all your data onto it (And don't forget the mail and address books and whatnot!), then format the old drive." Or, better still (and faster) buy a new drive and use it. Your old data is still on the old drive and can be copied across, leaving the original copy of the data on the older (probably smaller and maybe slower) drive. If the WORST comes to the worst and things go badly wrong, put your old drive back in and you're back to where you were before making any changes. Sweet :) Cheers, Cliff
