Under AHCI you need drivers for it to work(XP).

What are your full system specs.
Windows XP? Vista? 7

Swapping one to the other is not always fun, but for a storage drive not the os drive is should not be bad.

What mode were the controllers set to when you installed the OS? If they were set to IDE, then you may very well be lacking drivers.

My personal approach would be to do a complete just-in-case backup, boot from the OS distribution DVD, and do a Repair Install. It works so often!
