Been awhile since I messed with my drives but try this:

Go to My computer - right click -select manage - storage - disk management and initialize (BE CAREFUL WITH THIS AS IT MAY ACTUALLY FORMAT THE DRIVE, LIKE I SAID, BEEN AWHILE SINCE I DID THIS) it there.

I have 2 SATA's at home and I think that's what I needed to do to get the second one working. I'm at work right now and can't actually see the actual settings.
