I got the (disc) manufacture's utilities (which run on a bootable
FreeDOS CD) and ran every test over and over.  It kept telling me
the disc was fine.  I should have believed.

I always feel a little weird about discs because although the manufacture
and the BIOS agree on the geometry, FreeBSD always (over three or four boxes
with a half-dozen different discs) tells me the geometry is wrong.  It seems
so confident about it, I generally let it do what it wants.  But what does
FreeBSD know about the disc that the manufacture and the BIOS don't?
