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?
