The hard drive on my mid-2012 Macbook Pro 13" recently failed. I have drive from a mid-2010 model in an external case, so I tried to swap it in, but the machine would not boot. Instead, I got the blinking question mark. Am I missing something, or is the drive incompatible with the newer machine?
 
Thanks. I think maybe I would need to reinstall the OS....? It came directly out of the 2010 machine.
 
Turns out that the disk cable was bad. After the second failure I took it to a technician, who put in a new cable. He told me that both my drive and the cable were bad, however. That seemed unlikely, so I put the old drive in an external case and checked for myself. Sure enough, there doesn't seem to be anything wrong with it. So now I have my 2010 machine's drive in my MBP and the 2012 machine's drive in a case! Works for now.
