Pic 1,2 : the new 2012 cable does not fit on the old 2009 Mac.
Pic 3 : the 2009 cable on the 2009 Mac.
Pic 4, 5 : both cables 2012 821-1480-A (new but does not fit), 2009 821-0814-1 (defective, to be replaced).
Pic 6 : the clamp closed.
Pic 7 : the clamp opened with orange ribbon still in.

I could open the clamp with nail.
I could unscrew with PH00.
Some crews hard as mentioned.
Sorry for the bad pictures, I did not set my camera at max resolution.
Presbytes have good lenses !
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.
