I had a similar problem recently.  My drives were brand new and so I
believed that the problem had to be in the drivers.  In my case, there
was no corruption.  There was much patching and tweaking until I found
that some of my drives wouldn't transfer at the advertised udma5 rate.
Using hdparam, I set the udma mode to 4 and they worked OK though at
reduced throughput.  Before I was done, I switched to the hpt37x2
driver and found that the drives ran fine at the advertised udma5

IMHO, there is a strong indication that there be some problem with the
IDE driver in 2.4.18 and DMA.
