MacBook Pro could not see local drive.

Mijn probleem

Macbook could not find ( or even see ) local hard drive. Drive was pulled and tested with success. Placed drive in external drive sled and booted from. Drive was 100% OK. The cable from the logic board to the hard drive was bad.

Mijn oplossing

Replaced the cable. It was easy.

Mijn advies

Never assume the drive is bad.
