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. 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.Īlso iFixit has this part listed as 923-0104 and others have it as 821-1480-A. My question is do you think the new cables are backward compatible? The old ones are forward comparable. The hard drive SATA cable connects the hard drive to logic board. 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 OEM Apple replacement hard drive flex cable for MacBook Pro 13 Unibody A1278 (MD101LL/A, MD102LL/A). Here's the 2011 15" cable: MacBook Pro 15" Unibody (Mid 2009-Late 2011) Hard Drive Cable They also introduced an upgraded cable 821-2049-A, which replaced the original 821-1480-A. Here's the 2012 15" cable: MacBook Pro 15" Unibody (Mid 2012) Hard Drive Cable On later versions of the MacBook Pro Apple modified the HDD mount so it would prevent the case from pressing on the HDD cable. I think this is an attempt at solving the problems with the older cables. I noticed that this new machine has a much wider data path than the older cables. I got in a 2012 13" MBP with a bad cable the other day. 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.
