All SATA drives prior to a few months ago are PATA with a serializer on
the front end. It is likely that the firmware for the PATA Raptor is the
same as the SATA Raptor, so any problem affecting one would likely affect

Perhaps, but I found these problem descriptions by doing a search on
3ware controllers with Raptor drives.
In any case, my point is that the problem you described appears to be
a problem with the drive, not the controller. The fact that you don't
see the problem with the ICP Vortex controller is not proof that the
3ware controller is at fault.
