I have a certain combination of portable external USB 3 drives and cables that do not recognize my drive on my Mac Mini 6,2 running OSX 10.8.4. Changing the ports have not helped.
In short - All my cables work with some hard disk or the other and all my drives work with some cable or the other. The cable - disk combination combination that does not work on the MacMini does power up the disk and I can feel the disk spinning. The non working combinations do not even show up the drive in the
System Information app.
I just cannot figure out how to figure out what is wrong. A cable - disk combination that refuses to work on the MacMini works just fine my Windows 8 Dell Notebook. Is there any way to diagnose the problem? How?
