MacBook Pro 13" Unibody Mid 2012 Hard Drive Cable Replacement

Mijn probleem

2012 MBPro hard drive died. My gf took it out to the pool with her in 105 degree sun in Palm Springs and when she opened the lid back in the hotel room, it was stuck on a beach ball. Restarting only brought up the flashing folder indicating no boot drive. Must have gotten fried. I was able to attach it to my MBPro and recover most of her files but reformatting failed. So i bought another drive and installed, reinstalled OS, copied her files back... all seemed swell. Except that every time she moved the laptop around, it would go to spinning beach ball and require a reboot. I decided to replace the SATA cable and so far it seems to be stable. I have no idea why the cable went bad, I really hope that was the problem because the fix was so easy and cheap.

Mijn oplossing

Replacing this cable is so easy. There was a little bit of adhesive still remaining on the underside of the cable which was nice for initial placement, but I did add a little scotch tape on top of the cable. Especially because it has a little more slack than the original. I took up most of that slack by giving it a slightly wider arc where it travels under the hard drive and I think it will be fine. Plus, the new WD hard drive is thinner than the original so there is a little bit of space under it for where the cable does bubble up slightly.

Mijn advies

I had to replace both the hard drive and the SATA cable in a 2012 MBPro. I found cheaper cables on ebay and amazon, but none had the bracket attached. From what I've read, it is a PITA to thread the infrared sensor cable through the bracket so I went for a used cable with bracket from iFixit for about $40. I think it was worth the extra $15 as the repair went so quickly and easily and I know if there is a problem iFixit will be responsive. So don't cheap out, get the cable with bracket from iFixit.
