Won't help, as the onboard IDE Controoller isn't able to
do more than PIO/ATA4.
The reason you see the "degrade" is the driver tries
what the drives claim they can do, but the controller chip
fails..(or thats what I think happens..)
In any event, "it's normal".
Oh, and becareful with any drive requiring more than
LBA32 addressing.. The controller chip doesn't seem to be able
to handle that either..
