I had the exact same problem with a FIC SD11 mainboard (K7 Athlon 600) and a Maxtor HD - sometimes FreeBSD even reported WRITE errors. Did you try forcing it to UDMA33 to see what happens? When I used a standard IDE cable instead to force it to run at UDMA33 these errors went away (and IMHO UDMA33 is enough for most HDs anyway) UDMA66 is almost unusable on my FIC mainboard anyway, even under Windows - thanks VIA. Interestingly, on that board I got the same errors in Windows 2000, reported in the system log (when using an ATA66 cable).
