i am currently attempting to install a "new" ultra60 and i am also
seeing weirdness accessing one of the disks.  i have both a 4GB and
an 18GB disk installed.  the 4GB disk appears to work fine.  the
18GB does not.  basically, i have observed that write() to this disk
*is* working but that the return value of write(2) (or any variant,
newfs(8) uses pwrite(2)) is "0" indicating that no bytes were written.
this is why newfs complains "end of device".  i have performed some
experimentation with dd(1) on the disk.  if i write a sector, i get
a write failure (0 bytes).  but if i then re-read the sector, i get
the same data that i wrote previously that failed.  using 2 different
patterns for the sector to test, i have convinced myself that the
disk writes do occur, but somehow netbsd is reporting no bytes.
(these tests were performed on the _raw_ device.)

one additional oddity i've noticed is that the block device seems to
"mostly work", at least for newfs (perhaps it fails when newfs tries
to write a non-block-sized bit of data.)  newfs fails after creating
all the cylinder groups(?) ala.  the difference is below.


so, something is "funny" somewhere indeed.  i have no idea what yet.


.mrg.
