i use to have no problems with this, but recently when i installed norton ghost 9, and i did a backup on my C drive - it worked successfully. I then transfered that image file to my backup drive. I then tried to rewrite over that file to do another image, however it did not complete because it said i ran out of disk space. However the probelm is that when i went to go check, i cannot find the place where i am losing 90 gigs of data. I tried turning on hidden files, and everything but it just donest add up. All the files in that harddrive only amount to about 26 gigs and its a 120 gig harddrive, and it says that i only have 15 megs of storage left. Does anyone know what the problems is
