Part of the problem is that the HP controller in the drive expects to
see a high-level format on the drive. Back around HP-UX 7.0 I found
some arguments to mediainit (-GD I think; the finding was done by
running "strings" on the mediainit executable and looking for a
getopt(3)-style option parsing string) that got it to tell the drive
to do a low-level format and write a new high-level format as well.
Made the disk portion of a 7946 usable again after going "bad" and
being formatted in a PC for testing.
