    I know this may be somewhat of a dumb questions. I have two two drive external SATA enclosures that both have disks in a JBoD configuration. 1 is 2 500 GB drives and the other is 2 1TB drives. I want to swap the drives as my enclosure with the two 500 GB drives has FW800 and my other enclosure only has USB2. Both arrays are formatted in HFS+ as a single partition. So when I swap them and leave them in the same order in the new enclosures will I be able to access my data or will it all be lost?

    That's the problem with striping drives. If anything about it changes (controller, drives, etc) you can loose all your data. I would say swapping drives between the enclosure will only work if you can also swap the controllers, unless they are absolutely compatible (and even identical controllers with slightly different firmware could be a problem).

    Yeah just as I suspected and you said. The drives were completely unreadable.
