I am trying to install a WD 500GB SATA 3.0 drive. I am already runing a Seagate 200 GB drive with no problems. When I installed the new dirve, the BIOS saw neither drive, nor did the BIOS see the drive all by itself. This is the error I receive on both attempts: The error states Hardware Initiate Failed. Please check device!!! The BIOS does not be installed. Press <g> to continue. When I press <g> it tells me to reboot. Both drives are OEM and did not come with jumpers. The label on the drive says jumpers not required for SATA operation. A guy I talked to recommended setting the jumpers for CS or slave/master but when I saw the label, I was really confused. The new drive does appear to spin up as I can feel some vibration. I am running XP Pro on an ASUS A8V Deluxe board, with an ANTEC 380 watt PS. The system does not support SATA 3.0 but the drive is supposed to default to SATA 150.
