So, I put my two SSD's in and since I was having a problem with the non-boot disk dropping off when in sleep mode (See Here) I decided to put the two disks in Raid 0 and see what happens. Well, I am not able to get the Raid 0 disk to boot. I can read it and it is mounted when I boot into the original 1TB HD, but the OS does not load when trying to boot from the raid set. I tried to reboot and use the "option" key and the raid disk shows up, but when I try to boot from it I get a failure every time. Setup: OEM HD in stock location SSD #1 in SSD location next to stock HD SSD #2 in Optical Bay I am using SuperDuper for disk cloning. When the SSD's were not in a raid set, I could boot from either one. Any ideas as to what the issue is?
