My HD is 120 GB. It says I have used 101, but when I count all my data it only is 45 GB. So I'd like to recover all this missing space. Trying to use Norton Systemworks doesnt work, because I dont have the OS9 drivers installed on the drive as I never use OS9. Repairing the permissions and disk with disk utility didn't work either. Can I install the OS9 drivers without wiping my drive and starting over? Thanks!
