You could just try "hdparm -N p3907029168" (capacity of the 'larger' disks)=
, but that could fail if the device driver is indeed buggy.

Another possible course of action would be to try that on some other contro=
ller.
For example on your motherboard you have two violet ports, http://www.gigab=
yte.ru/products/upload/products/1470/100a.jpg
those are managed by the JMicron JMB363 controller, try plugging the disks =
which need HPA to be removed to those ports, AFAIR that JMicron controller =
works with "hdparm -N" just fine.
