My daughter is still looking for the disks that came with this MBP when I bought it for her. I understand there is a hardware test app on them.

Thanks for the help everyone.
Sorry but that isn't what I suggested at all. That's just repeating what you did to start with. You need to install to the external from a DVD as I described, bypassing the internal disk entirely

External hard disk acquisition addict - but admitting the problem is the first step to a robust backup
