I gather from this that the 2842 is 'mostly' reliable :)

from the talak we had with Kirk McKusick the other day..
try the following....
set the disk up with a disklabel that suggests a geometry
of: 1 head, 4096 sectors per track..
and then repeat the test.. (or newfs the partition with that geometry
if it's possible) and let us see if there is a difference...
