SATA HDD not detected by BIOS but...

I need some help. I just got a WD SATA II 500gb hard drive. My motherboard is MS-7050 that supports SATA II and it works fine with an IDE hard drive.

The problem is that when I hook up the SATA drive the BIOS doesn't recognize it...but I was able to run the WinXP setup CD and it installed XP onto the SATA drive...but after install the Bios still doesn't recognize the drive. I used a boot CD and was able to run a WD hard drive diag and it said no errors then the PC rebooted right into Windows! I rebooted after that and it says no hard drive! So the only way to get the computer to recognize this drive is to run the diagnostic and it works every time.

I have tried 2 different sata cables/power cables, i have checked every setting in the Bios, i have flashed the Bios...this is really frustrating...I just want to be able to turn the computer on every day and have it load right up.

One thing that I have noticed is that when the computer boots, the hard drive does not spin at all. When i run the diag on the drive I can hear it spinning.

I had this problem a while back (I like IDE, not SATA.). The reason that the BIOS doesn't detect it is because (in most cases,) The BIOS is set to auto-detect the drives on an IDE bus only. I am guessing that the WD disk is using a Disk Drive Overlay. You should try using one. The reason why to use one: "A Disk Drive Overlay (DDO) allows the Hard Disk drive to be accepted by the BIOS."

I did some research on DDO and Western Digital recommended using the Data Lifeguard tool to set that I ran that and ended up repartitioning the drive, i made 2 separate partitions, then reinstalled Windows...after installing Windows, i shut down then hard drive detected! How do I ensure that DDO is installed on this drive?

Still cannot get this working but I did more research and I found another listing of mobo specs and this time it says "Each connector supports 1 serial ATA-150 disk drive" - this hard drive I have is a SATA 300 drive...but I have it jumpered for 150.
