Second hard drive seen in bios but not windows


Feb 23, 2012
I have added a second hard drive (a Hitachi 500 gig) to a Dell GX 280 computer. The drive is a SATA as is the boot drive. When I went to Bios to turn on the second drive it sees something but can not identify it. This second hard drive is not seen in windows either. I do not know where to go from here. Any help would be appreciated.
The Hitachi hard drive does work in two other computers. It is formatted and It has data stored on it. These show up on the other two computers.
