Recently I have had hard drives consistently becoming "disabled" on my new AsRock EP2C602-4L/D16.  At first I figured it was because I ripped out the unRAID USB drive from a Quanta S210-X22RQ and into the AsRock motherboard.  Probably not the wisest move but it worked out, well, unRAID installing itself on the new hardware and working it's magic to recognize all previous devices part worked out.

In this "guide" you will find exactly everything I used to make this happen.  Some things can be changed to fit your specific needs BUT I haven't tested anything else beyond what you will see and find in this guide.
