I just got my new Seagate 2TB internal HD today. Hooked everything up, booted up, went to BIOS and all looked ok from there. Windows 7 boots up but only shows my Samsung SSD 120GB and my WD 300GB Raptor HD the Seagate doesn't show up. However if I got to device manager it shows up there. What's going on? Why can't I see all my hard drives?
