I installed a WD250 SATAII drive on my ASROCK dual939 SataII board using Vista Operating system. I had to set Bios to non-raid and SATAII...When I booted the drive showed up as WD250 ATA device. I then used the Boards CD and found SATA 2 driver for win2000/xp identified as JS32 and installed it. When it rebooted the Drive is now identified as a SCSI device. Any suggestions???
