Got a new 2012 27" iMac and I can't get it to boot to my Thunderbolt Drive.  I can use my 2011 iMac and 2011 MBP and it boots to the Thunderbolt Drive just fine.   Thunderbolt drive is a Little Big Disk SSD drive.


After start up I get a chime, white screen then a cycle with a line through it then about 30 seconds later the iMac turns off.  Any Ideas?
