How do you copy the contents on your hard drive on to a hard drive in another 7 computers?

The easiest, fastest, and best way to do this is to use Symantec Ghost. Hook both the 'image' hard drive and the 'clone' hard drive in one machine and boot the computer using the Ghost CD. Setup the CD to copy from one location to the other (be careful you are copying the right one or all you data will be lost!) and you will end up with a perfect copy. If you don't trust this method, you can always hook up both hard drives, and copy files manually from inside the operating system, although that would take days longer than about half an hour using Ghost for 7 hard drives.
