Robert: I use cabon copy cloner form bombich software. http://www.bombich.com/software/index.html It's free to individual users. I use an external firewire harddrive to clone it to. Than I boot from the external drive to check it out. Than I reverse the process to get everything going again on the new drive. It does take a fair amount of time to transfer everything.
