Ответ на "Dual Hard Drive kit with Samsung Pro 840 256"I wish we could get some confirmation on this from iFixit. It is a bit of an expensive endeavor to find out the real cause of the problem. In addition to what I've said earlier - I have tried to plug in the two SSDs I have into an earlier model of MacMini (Mid 2011). Still using the cable I bought from iFixit. And everything was functioning properly. So, it is clear that the SSD are functional, and that the cable is functional. What is still unclear is whether the cable is incompatible with late 2012 models, or that the secondary controller on the Mini is faulty. From what I gather - all of these parts should work with Mid2010 and later models.
