You don’t say what the Current Transfer Modes are, which would be interesting.
However. If the Current Transfer Mode for any of your devices is PIO Mode, then that will need changing.
here is a link to a download for a little script, which will reset any IDE channels on your system that have slipped into PIO Mode.
If you’re not comfy with doing that, then you can follow the instructions in this thread, to delete the offending IDE channel manually.
Edit: Hehe, bjkg beat me to it
