I am replacing the HDD in my mid 2009 MacBook Pro 13" with a new unit. The old one is fine, just full. The old HDD is a 160GB 5400RPM unit. The new one is a WD Black 500GB 7200. I installed 10.8.3 on the drive with it connected via USB and the Command R command. I was able to boot to the new drive (with the old one installed) with the Option held while booting and it connected via USB. I checked, repaired and verified the new disk and it was all 'OK.' When I install the new drive into the bay and restart I get the Folder with ? mark. I must be missing something simple?
Thinking it was the SATA ribbon, which I had replaced last fall, I swapped the drives back in. The old drive works fine. Multiple swaps results in the same. New gets the folder with ? Old boots up great.
