Its a Thunderbolt adaptor desk drive paritioned into 16 partitions.  It mounts fine on my iMac 10.7.5, 3.4 GHz, but when I switch it to my MacBook Pro, 10.8.2, 2.6 GHz, it won't mount. Error message says its unreadable.  But it does appear as "connected" in the System Profiler, and appears as one disk icon in Disk Utility, but not the 16 partitions. 

MacBook Pro (Retina, Mid 2012), OS X Mountain Lion (10.8.2)
