So I just got an external Firewire drive and I want to be able to boot off of it incase something goes down on my internal HD. If my internal fails, I want to be able to carry on like normal, but using my external instead of my internal. How can I do this? I only have the system disks that came with my iBook, and they won't let me install onto the external drive. I tried just copying over all my system files and all that from my internal HD, but the Firewire drive was not recognized as a bootable drive. Does anyone know a way I can do what I want to do?
