My MacBook Pro locked up one morning on 'wake-up' as I started my work day.
Initially, I thought that this was a hard drive failure, but found that my laptop would not boot from another bootable drive I kept after a hard disk upgrade.
I purchased the hard drive cable with the bracket, so the process was a bit simpler than a repair with bracket reclamation. I was very careful about bending the new cable as needed for fitment since over flexing may have been responsible for the failure of the original cable.
After installation, my MacBook again worked as expected.
Because I use this computer for work, I was concerned about not being able to use it for an extended period.
Rather than take my laptop to a service center for the repair, I verified that it would boot from the original drive in a USB-connected external drive case ($30) after performing a network boot. Then I ordered parts from iFixit. This configuration a bit slower than an internally connected drive, but satisfactory for getting work done until I could do the repair.
