I recently replaced my Color Classic Hard drive that died with another original 80 mb drive from a spare parts cc I had picked up some time ago. The drive is filled with stuff I have no use for so I decided to simply run Apple HD Setup and reformat the drive and do a clean install of 7.1. When I try and format the drive it fails...I get this message...cannot unmount drive due to an open file. Tried an install from the 7.1 disk and again the install fails.
Can anyone suggest how I can resolve this problem and do a clean install? Help would be very appreciated!
