hi i recently brought 2 WD 1.5TB 3.5" Hard Drive - SATA-II 5400rpm 32MB Cache - Caviar Green OEM and pluged them into my system but it both seems to be a dud. in my bios it auto detects the hard drives but then i get a primary slave drive and/or secondary slave drive error. when i try to enter my bios is freezes or just keeps restarting. i tested each drive and keep getting the same error. any help? much appreciate.
