Hello guys! I am new here so please bare with me, I hope im posting this on the right place.
So bought a Samsung SD 750 EVO Solid State Drive to use as an external drive on mu Mid-2012 MacBook Pro.

I also got a Nisuta 2.5¨ HDD enclosure case with USB 3.0 to Sata adapter.

The problem is that my macbook does not recognize it and wont let me do anything to it either. Can anyone help me put please? I´ll attach info and prints of the errors. MANY MANY THANKS

Have you tried the Borrar option? The partition map needs to be GUID if you are solely using the drive with your MB Pro. After you erase see if the Partition option is enabled.
