I finally got my machine to where I now have an 80gb usb hard drive. If I understand clones (used true image backup before), I can make a usb hard drive copy of my entire disk. Should have: 1. Settings for my machine 2. Pictures 3. documents 4. outlook express 5. Favorites In effect, it will give me a total hard drive I can copy back to my machine in the event of a failure. Right? When you do this, and come to files which may already be on the main machine hard drive, will it keep the program going and ignore/skip over those areas---yet fill in what's missing? Anything to watch out for?
