I have Windows 10 Home edition with 16GB memory and a Gigabyte GA-Z97X-Gaming 7 motherboard. My Toshiba HDWD120 2TB shows up in the bios but does not show up in the device manager. I have checked the cables and connections by switching them out with other drives that are working properly and it still does not work. I have a 500GB and a 1TB hard drive along with a 320GB SSD drive that are all working properly. Any help I could get with this problem would be greatly appreciated.
