Using new hard drive cable in older machines 821-1480-A
I've seen so many problems with the hard drive/IR cable in the 2009-2011 MacBook Pro machines, I want to try the newer cable, 821-1480-A. I got in a 2012 13" MBP with a bad cable the other day. I noticed that this new machine has a much wider data path than the older cables. I think this is an attempt at solving the problems with the older cables.
Here's the 2012 15" cable: MacBook Pro 15" Unibody (Mid 2012) Hard Drive Cable
Here's the 2011 15" cable: MacBook Pro 15" Unibody (Early 2011/Late 2011) Hard Drive Cable
I didn't have the new cable in stock so I used the 922-9062 till I could get the new cable shipped in: MacBook Pro 13" Unibody (Mid 2009/Mid 2010) Hard Drive Cable here's the new one: MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable
My question is; do you think the new cables are backward compatible? The old ones are forward comparable.
This is also proof to me that Apple is aware of this issue with the cables but has done nothing to resolve it for their customers.
Also iFixit has this part listed as 923-0104 and others have it as 821-1480-A.
The two holes that attach it to the frame are wider on the new machines but you can use just one screw to hold it in place.
Is this a good question?
