I have been attempting to get an MO drive to work under BSDI 2.0, and have had
intermitent success.  I was able to get an MO cartridge to hold an active
filesystem last week by first using disksetup to set the label and designate
a partition on the cartrigdge, and newfs /dev/rsd2h created the file
system properly.  It was used fairly heavily over the weekend, so I know that
the process worked.

When I attempted to perform the setup process again on another MO cartridge,
I repeatedly get a "Write Error" on the sector numbered Exactly 1 less than
the last sector in the partition when I ran newfs.

I performed some checks and found that the disk labels differed, the MO
which worked last week has a bytes per sector of 512, while the newer ones have
a bps of 1024.  The total sectors on the newer MO is half the number on theMO
used last week.

When I tried writing the label from last weeks MO to the newer one, Disksetup
didn't complain, but newfs did, this time with a Logical Block error.

Am I remember the steps I performed last week incorrectly?  Did I do
something them that I am forgetting now?  Does anyone else have experience
getting MO cartridges to work?  Are there any pointers or references
available?


Thanks in advance for any help you can provide!
