New SSD not mounting in Recovery Mode on 2012 MBP
I'm replacing the HD on a model 9,2 2012 MBP with an OWC 6G SSD. I ran a Time Machine backup on the original 500G HD and then swapped the drive. I cannot get the new SSD to appear in Recovery Mode to format it and install OS X. I have tried with the original drive attached in external enclosure, same with the Time Machine backup drive and I have tried with no external attached at all. (Following the drive upgrade instructions on the OWC website http://eshop.macsales.com/articles/how-to-transfer-your-data-from-your-old-drive -to-a-new-drive) I then removed the SSD from the MBP and attached it to my Mac Mini in an external enclosure. It mounted fine and I was able to format it. So, I ruled out a faulty SSD. Then I restarted the MBP with original HD installed and the SSD connected via external enclosure. Ran Disk Utility and formatted the SSD. Shut everything down again and put the SSD back into the MBP. Booted into Recovery Mode to install OS X and the drive will not appear.
Currently out of ideas. I've double checked all components and everything should be fully compatible.
Ideas??
