Does yours say in the spec it's UltraWide? (I guess they may have updated the drive and kept the same ID, i.e. ST34371W)... I also get problems if I leave Tagged Command Queuing enabled, there again I also seen to be getting problems with it completely disabled, but not as many (and nothing sadly relating to Parity)...
