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 the other. > The other one applies to SATA drives.

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. -DG David G.
