Hey all,
I recently acquired an OCZ Agility 2 SSD. I popped it in and installed Windows 7 64-bit on it. Then, I also ordered a WD Caviar Green HDD, and popped it in as a data drive. Bios recognizes that the slot has something in it, but it can't tell what it is. The disk does not show up in either the data nor device manager.
Any clues on what might be wrong and how I might go about fixing it?

Motherboard: GIGABYTEp P55-USB3 Rev 2.0
SSD: OCZ Agility 2 60gb
HDD: WD Caviar Green 1TB
Windows 7 64-bit
