Sounds like your wd0 and wd1 claims to be Ultra-DMA capable, but the
first Ultra-DMA data tranfert fails with some kind of error (the error
reported, "bad block detected" is strange anyway ... I'll look at the errors
definitions, maybe they are wrong for DMA commands). After 2 failures, the
driver downgrade to DMA mode 2, which seems to work better.
The fact that both drives fails the same way would point out some kind
of hardware problem ...
