I am guessing the best drive to buy would be a firewire drive. I am wondering if firewire drives can be either firewire 400 or 800, or will they be one or the other?

I think I will use Superduper! As I read the documentation for Carbon Copy, it seems there was some risk to their process.

Do any of you have experience making bootable drives, and do you offer any procedures to use in the event it is needed for that purpose? How do you use a bootable, external drive to start a computer and then put that image on it?
