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.

The problem was that I was running it off of a HP 9000 Series 200 and only had access
to BASIC and Pascal. They have routines for high level formatting a drive but not LL
formating. On some drives the high level format command seemed to do the LL format as well
and I could replace the internal HD, run format and all for well. But on other drives I
couldn't get the high level format to run. I don't remember the error msgs now
but it indicated that the drive needed a LL format. I had a whole pile of defective drives
that I played around with and IIRC I was able to replace the internal HDs in those that
used Seagate drives and reformat them successfully but not the ones that used the Vertex
or HP built HDs.
