First off heres what I got. the latest 12 core (2 x 2.4 GHz 6-Core Intel Xeon) Mac Pro. 64 gigs of ram (64 GB 1333 MHz DDR3 ECC) ATI Radeon HD 5770 1024 MB running OS X 10.8.3. I have a one T 7200 HAD and a OWC 256 SSD drive. I use the SSD as my main startup drive and the 7200 HD and back up and storage BUT when i first got this machine going I cloned the SSD to the 7200 HD. Without me changing the start up drive, in the last 2 months 4-5 times when I started it up it started up from the 7200 HD.?????? I had to go rest the start up drive to SSD! Whats up with that?
