Guys - I was so looking forward to my optibay with 256 g sandisk SSD arriving. I installed it as per instructions and used carbon copier to clone my hdd onto it. But it just won't boot from it no matter what I do! I set it as a default - upon boot the crossed circle shows up for a few seconds and then it boots off of HDD. I held option key and selected it - it shows up but boots off the hdd anyway. The option key trick half the time doesn't show the drive as bootable at all. I reset PRAM - no luck. So far as I can tell, this MBP has SATA 3 on both optical and main drive ports. I do have FileVault enabled on the main HDD. I just want it to frigging boot off of the SSD! Any thoughts ?
