I just bought a new hard drive for my macbook and came in today. The combo came with the hard drive and a enclosure case. I want to keep all my files from my old hard drive, and want to transfer my files to the new hard drive. I don't have any other external hard drive to back up my files. Here is my question. Can I place my old hard drive in the external enclosure case I got, and put the new one in my macbook, so that I could boot leopard from my old hard drive in the external closure and use a superduper! (or other programs) to make a exact copy of my hard drive into my new one in the macbook. Of course I would first partition the new hard drive, but I'm just not sure if I can boot leopard off my old hard drive in the external enclosure. Thanks.
