I just bought a new Hitachi 1TB hard drive (model no. HUA721010KLA330) for my Dell Optiplex 320 tower computer (motherboard model no. CN-0CU395-70821-76L-D1T2). I hook it up and look in the bios and it is never detected. I have all of the SATA ports on and I know that the connections are secured correctly. I can also hear the drive start up. I have an older drive that works fine in my computer. Please help me out here! Thank you in advance!
