First Build - Help Needed with BIOS Detection Issues

[PrettyPinkPonies]

As of recently, I received all the parts for my build, and after a few unsuccesful attempts, have managed to get things running fairly decently.

I do have one slight problem though. In the BIOS, my WD Raptor 74GB HD isn't being recognized for one reason or another. My Seagate 250GB 7200.9 HD on the other hand, had no problem being detected and was auto-detected upon first start-up. Both use SATA.

My BIOS reads:

Primary IDE Master: Not Detected
Primary IDE Slave: Not Detected
Secondary IDE Master: LITE-ON DVDRW SHM-
Secondary IDE Salve: Not Detected
Third IDE Master: ST3250824AS
Fourth/Fifth/Sixth: Not Detected

I checked IDE configuration and enabled all SATA ports, and disabled the nVidia RAID Function. I've read the SATA Guide, checked out both WD and Seagate's site, but I have made no progress. I also checked to see if I could hear any activity from the drive, and I definately can hear it spinning upon startup. My motherboard is A8N32-SLI Deluxe. This is some what of a major complication, since this was going to be the drive that I was going to install my OS to (which I don't have at the moment). Any help would be greatly appreciated.
