I run Win7 off a 500gb Sata hd and recently bought a 1.5tb Sata hd for back up purposes. Installed it, booted to bios to make sure it was there, and loaded windows. I had to confirm which drive I was loading from, which I took for a good sign. Then windows loads up and doesnt show my new drive. This is my first build so Im not sure if its something I did or what. The new drive is plugged into the mb in the sata 2 slot, and the bios recognizes it. Can anyone help me?
