So I'm upgrading a Macbook Pro 8,1 with a Crucial M500 960GB. Hooked up the M500 with Apricorn externally and formatted the drive. Installed 10.8. MBP boots fine from M500, and the internal drive is visible. Then switched the drives, with the M500 internally in the main bay and the HDD external. When MBP is started, I get the gray folder with ?. Can't even see the external HDD or anything else, even holding option key. Just internet restore.
Checked Apple forums and texted Crucial tech support. Both said it was the HD cable. So I just went to the Apple store and they replaced it with a new cable. No difference. Same behavior. It must be the cable, but other people are using this SSD with MBP 8,1 and it works, so I am puzzled.
Any suggestions?
