I have 4 hard drives (Mac OS Journal formatted) that I want to move from my Mac Pro to an external enclosure. Then I want to be able to access the drives with my new Mac Pro. They contain data now and I obviously don't want to format them. Do I need to do anything to set up the external enclosure? Should I set it up first, attach it to the Mac Pro and then transfer the data? Or can I just remove them, pop them in the enclosure and connect to the MP? Any recommendations on a 4 bay enclosure?
