MacBook Pro 13" Mid 2010 Drive problems

Mi Problema

The drive appeared to be failing with lots of beachballing. Took the drive out to connect it via an external carrier to another Mac and it worked perfectly. So I knew it was the controller or cable. Googled and for some reason this is a common problem. I'd love to know why?

Mi Solución

Easy. 5 minutes.

Mi Consejo

If you have drive failure symptoms on your MacBook Pro, check the cable first.
