a WD 80Gb, as in a single hard drive on the HPT374 ?

my first 2 chanels seems to be OK (couldn't test them good)
but they survive hdparm -d1 -u1 -c1 -X69, where as the 3rd & 4th chanel
reported UDMA4/5/6 not functional (or smth similar) and the system went down

there might be smth similar here, but i get the lockups even if i don't play
with /proc/ide hdparm, and 1st, 2nd chanel are running at UDMA100 3rd, 4th at
