That was the first thing I tried.  I went down in mode all the way to
PIO/DMA 0 (0xFF8).  Still had the corruption issues after a couple of
hundred megs of writes.  It takes hours and hours to do that in PIO 0,
if you ever get the urge.

Considering where the IDE controller resides, I'd expect a heat
problem to be more dramatic and less consistent across four different
brands, sizes, and generations of drives.

I'm told the other 4801 is doing fine, and has had no problem doing
kernel compiles, etc.

Thanks to all for your ideas.
