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?
It probably needs to be formatted. Depending on the version of Windows installe4d you can get there either
(Win 7) Right-click Computer in Start Menu, click Manage, click Disk Management
(Win 8/8.1) Right-click the start button or the start screen hint in the bottom left-corner, in the menu that comes up select Disk Management
In Disk Management, you'll see the drives as rows across the page. Right-click the unformatted 1TB drive and create new simple volume, follow the wizard to format
