UDMA ICRC error

I occasionally get those errors as well. When I'd boot, the drive would 
try and
do ATA-100, fail, and revert to PIO-4. (I blame the cheap PCI IDE card, 
it came free
with a hard drive, and I have to use it, since the nforce2 chipset on 
my mobo
won't see anything but primary master and secondary master under FBSD.) 
I can
make it work by setting the drive to ATA-33, though. (The command, for 
me, is
# atacontrol mode 2 UDMA33 xxx
but check the manpage to see what options you should use.) I've been 
using the
hard drive for about 7 months now, and it works fine. I don't put 
anything I
care about much on it, though.
