The main SATA controller on my Mid 2012 13" MacBook Pro stopped working?, it does not see any hard drive connected to it (Disk Util doesn't see it, and Disk Util takes awhile to come up, doesn't matter what size or kind of hard drive is used). HOWEVER if I do a System Report, System Report shows the the drive info. Is the SATA controller kinda dead or is there something I can do to get function back to the main SATA controller? DVD-ROM drive works fine reads/writes CD/DVD's with no problems, it just won't boot or format the main hard drive. I ordered a drive doubler with OWC (macsales.com), but I didn't read the fact that the 13" unit DVD/CD drive controller will not handle SATA 3.0 6Gb/s drives well before I ordered. So I will put the stock drive there, but I have a brand new SSD drive that is SATA 3.0 6Gb/s drive and would like to use it.
