Thank you Ifixit and Andrew "Optimus" Goldberg, the parts and tools arrived today i went to the shop to buy lunch when i had returned (15 mins later) my Husband had replaced the part (hdd cable) and my Macbook pro is super speedy again. Nice repair guide thank you i doubt i can say thank you enough.
After many hours of trying to get my SSD drive to work, I read elsewhere that other users had issues with the HD cable that came with the laptop. From when I opened the envelope until my SSD booted was less than 30 minutes. If you have the right tools this is an easy fix. Just keep in mind that there is adhesive on the cable that goes to the bracket -- don't forget to peel off the paper backing and line it up correctly.
Hello, I have a mid 2009 Macbook pro 13. I have bought a hard disk cable that looks almost the same as the original one except for greater width and shorter length. I guess that this new cable fits the 2012 model, SO YOU MAY HAVE TO UPDATE THE GUIDE accordingly.
Electrically the wider cable also works on the mid 2009 model (at least for disk access) though it does not fit mechanically.
My friends be careful when you buy this part.
thanks, Ifixit! Like many, my laptop developed the flashing question mark with startup even though when I removed the drive and put in external enclosure it worked perfectly, and putting in a different HD with a good system install on it also failed. thankfully I found out about the ribbon cable issue with a web search. The part fit perfectly and was easy to install, took about 10 minutes and I was up and running again.
