New internal hard drive not spinning on MacBook Pro A1278 13", Mid-2012 The Hitachi 5K750-500 initially installed in the MacBook A1278 13", Mid-2012 failed. I bought a new hard drive (Seagate ST500LT012) but it was not detected by the Disk Utility.

I found that the hard drive is not spinning when installed in the MacBook. When I plug this same drive on a PC it works well and I can hear the disk rotation. I tried two other hard drives on the MacBook and I can hear the disk rotation.

Do you have an idea what's going on and what I can do?

Edit: I tried two more hard drives. Here's a summary:


Seagate ST500LT012 (SATA 3): Not even spinning a second.
Western Digital WD5000LPVX (SATA 3): Spinning for a minute then stops. Not detected in Disk Utility.
Seagate ST9750420AS (SATA 2): Spinning, detected.
Original Drive Hitachi 5K750-500 (SATA 2): Was working before being faulty.


Is this SATA 2 / SATA 3 related? 

Edit 2 : Fixed by replacing the "always faulty on the Mid-2012 MacBook" SATA cable.
Surely not all those hard drives are faulty, so I'd look at the SATA controller or cable. Seems you may already have figured that out though.
