In case anyone is interested I may have figured out why this is happening. The problem is related to a BIOS setting and the SATA port the hard drive is connected to on the motherboard. In your BIOS settings you will find a setting called "sata ide combined mode". If it is enabled it causes SATA ports 4 and 5 (and possibly 6) to act like PATA compatible ports for SATA optical drives. So if you have an SATA optical drive then keep the setting enabled and move your hard drives to SATA ports 1, 2, or 3 and optical drive to 4 or 5. Anyway, this solved it for me so hopefully someone else can try it out.
