Dantastics drive seems to be an Internal IDE drive from the Model Number that he posted.

The only other thing that I can think of that can cause this is if there is another drive plugged into the Same IDE cable as the Plextor. If you have another drive that is attached to the same cable as the Plextor, then try unhooking this drive and then see if that works.

The other thing to try is make sure to update the Motherboard drivers from the computer manufacturer. The chipset drivers control the IDE interfaces on the motherboard, and can fix this issue also.
