I had a 2012 MacBook Pro with an OWC Data Doubler instead of the SuperDrive. My 2012 died and I bought a 2016 MacBook Pro. I removed the drive (a 1TB WD hard disk drive) from my old 2012 MacBook Pro to get some data from it by connecting to an external USB enclosure but I can't seem yo mount it.
Does anyone know what the problem might be? and/or how to solve it?
