I have that board - and my WD HDD was plug and play. No messing with the BIOS needed.
I'd try the other SATA - as suggested.
Was your HDD ever recognized - and disappeared after a specific BIOS change - if so - what specific BIOS change did you attempt that caused this HDD not to be recognized.
OR -
Was the HDD never recogized by your MOBO? Are you running a Molex Power cable to your HDD along with our SATA cable?
I have tried other SATA, but obviously I haven't tried all of them. I also have my dvdrw plugged in SATA as well. Do you want me to move that around as well or just the hard drive?
Yes, HDD was recognized as master. What the weird thing was that it was recognized in SATA 3 or something else when I had it plugged in SATA 0.
What I have tried with BIOS is the following so far. ( They all didn't work)
1. Changed time and date -> changed boot order -> disabled IDE under "Integrated Peripheral" -> save and exit
2. Load optimized defaults -> save and exit
3. Load fail safe defaults -> save and exit
