I have bought a new rig. For the hard drives, I have chose the samsung 840 evo ssd 120gb and the seagate barracuda 1tb hdd. When I have installed windows, the two hard drives were plugged and I chose to install windows on my ssd. But, now, my hdd is plugged, detected by the system, but not in the list of hard drives. Whan I need to do for that it appears on the list of hard drives?
