My computer crashed about a month ago. Apple said that it was the logic board that crashed. In order to recover my data, I disassembled my MBP and took out the harddrive and put it in an external enclosure. Now, my new computer is not picking the external hard drive and nothing shows up on the desktop. The light is colored on the enclosure, indicating that it is working, and I can hear the harddrive as well. Does this mean my harddrive crashed and apple was wrong? Any suggestions?
