My girlfriend's hard drive started clicking... and then failed. Years of pictures and documents and no backups to be found! The horror!
I purchased this bit driver kit in an attempt to dissect my other hard drives and replace the circuit board on the failed hard drive.
It went good... and not so good (but not bad, yet!). I tried all of the random 2.5" drives I have, but none of them were completely compatible with the drive I was trying to fix. I removed the circuit boards and the failed hard drive started spinning without clicking! Unfortunately, none of my combination of computers, wires, or external drives would recognize the drive.
I am still working on this one, but if you have a clicking, failed hard drive... not all is lost! You need to find the exact model of drive that failed (or so I believe/hope)... pop open a couple of Torx screws, swap, and cross your fingers.
