3TB WD first recognized as 746GB, now not at all

Community Manager

I have an intel DG965OT motherboard, I previously had 2 Seagate 1.5TB hard drives that worked fine.

I recently picked up 2 Western Digital 3TB hard drives which I'm having problem getting the system to recognize.

When I first installed them, I went to Windows Disk Management and they were only recognized as 746GB drives. I researched the problem, it was recomended I install Intel Rapid Storage Technology, so I did. Now after the restart the drives aren't recognized at all.

The BIOS recognizes them in the Boot Disk Order, but nothing after Windows boots. I looked for a BIOS update, but the Intel site says there isn't one for Windows 7 64bit.

Any feedback or input would be greatly appreciated, I'd really like to utilize these drives.
