I recently built a new Intel system. Gigabyte GA-X58A-UD3R Rev 2.0. I'm running an i7-950 with 12GB of RAM and a Sapphire 6870 video card. I installed one Crucial C300 64GB SSD and one 1TB WD Caviar Black drive (64mb cache). I set the BIOS to AHCI on the SATA3 6GB/s controller and proceeded to install Windows 7 on the SSD. Everything seemed fine. Got the drive up. Installed the motherboard drivers, then the video card drivers and then installed antivirus software. I connected to the internet and I thought everything was great. I proceeded to install the WD drive on the other port and used it as a data drive. I started installing programs and transferring files and started running into some serious issues. First, the system starting becoming unstable freezing randomly and slowing down unexpectedly. Second, I noticed that the drives are being recognized as IDE drives and not SATA drives. Finally, the SATA3 RAID configuration utility in the BIOS doesn't work properly. Am I doing something wrong here?
