What if I have a set that was created using a version older than OS 10.4?
MacDrive supports version 2 (the current version) of Apple RAID technology, which has been included from OS 10.4 on. RAID sets that are older than this use version 1 of Apple RAID, and are no longer supported in current versions of the Mac OS. For that reason, we do not anticipate offering support for such drive sets. If the RAID is re-created using a more recent version of the Mac OS, you can use it with MacDrive Pro.
