I wanted to put a SSD in my mac mini and put the 500gb disk in as a secondary disk.
There were no problems during the operation :) This product is one of the best I have bought online ever! Great stuff!
After my own Mac Mini was fixed, I suggested the same operation for a friend, and he performed it while i was guiding him, and his also works perfect :)
No.. It all worked out beautifully ;)
