Pretty much everything else is working perfectly.
What I've tried:
* I saw that someone had luck enabling "hot plug" in the BIOS for that port. Didn't make any difference.
* Made sure that the checkbox for "Put hard disks to sleep when possible" is unchecked.
* Updated the firmware on the motherboard to the latest available.
Any help would be appreciated.
