These messages usually mean a problem on the IDE bus; if recovery goes
well you shouldn't get any corruption.
Now, in reality, as this mean a problem on the IDE bus, when running in
multiword DMA there may be some errors on the bus which don't get reported to
the software. This shouldn't happen with Ultra/DMA as it includes data CRC
