Replacing MBP cable

Recently, my mid 2009 MBP (Model A1278) fails to recognize the hard drive. My first bet was another disk failure on me, but it was not the case. I took down the hard drive and put it to a mobile hard drive case and it can be read smoothly.

It turns out that it is due to the SATA cable fault, which is a notorious problem for mid 2009 MBP model. See the threads and discussions here, here, here and here.

Luckily, the solution is simple, just go ahead and purchase a replacement cable and replace it. iFixit has a very detailed illustrated document on the procedures. However, Amazon has a cheaper option, and it works fine for me. I didn’t test the infra-red though, since I never and not plan to use it.

There are other common issues for this model, and they can be easily fixed. See my following posts:
