Hello. I have a dell dimension 3000 running windows xp sp2. I am using Acronis T.I. version 9.2337. I have an internal 40GB hard drive, and an 80 GB external USB drive(hard drive in an enclosure). I have my full disc images stored in a file on the external drive. I want to switch drives, putting the 80 GB inside the computer, and wipe the 40GB one clean to use as the external drive for storage. Can someone explain the best way to do this please?
