Just an FYI for yall. I plugged in two multi-drive RAID 0 enclosures. 1xLacie 500GB, and 1xcustom built 1.5TB drive. Neither worked with APX. The base station saw it, but wouldn't mount it. Spent some time with AppleCare, they determined that it was because they were RAID 0 multi-drive drives. I tried a single drive with a generic USB 2.0 port and it worked instantly. AppleCare did say there may be a fix for this coming soon now that they know about it.
