Well, the problem there is that your drive can't do UDMA at the speed it is trying to. Replace the cable, make sure it is an 80 conductor cable conforming to the standards for IDE cables, most specifically, it should not be longer than 45cm. If that doesn't help, try setting a lower UDMA mode with atacontrol(8) or disable it completely via sysctls.
