There are two ways to use the MO: first as a super floppy, second as a
partitioned hard-drive. Explaination follows:

1. create a dosdriver like this

        Device = omniscsi.device
        FileSystem = l:FastFileSystem
        Unit   = 2
        Surfaces  = 2
        BlocksPerTrack = 11
        LowCyl = 0
        HighCyl = 79
        BufMemType = 1
        GlobVec = -1
        SectorsPerBlock = 4
        Activate = 1
        Buffers = 30
        DosType = 0x444f5303
        Mask = 0xffffffff

Device and Unit need to be adjusted for your setup. Maybe Mask.
SectorsPerBlock and DosType if you like (see your Amiga Manual).
If you have ffs v44.2 you don't need to edit anything. Values for
Low/HighCyl, Surfaces and BlocksPerTrackare questioned from the drive.
If you have v40.1 or earlier, use an utility like scsiutil to get the
number of blocks on the drive (scsiutil ... -c). Values are only read if
there is a medium in the drive. Then imagine settings for L/HCyl, BPT and
Surfaces, which multiply up (nearly) to this, and use them. These values
can also be used for HDToolBox to define a new DriveType for the MO.
Now you can mount the drive and format it amiga-wise.

There is no need to low-level format MO-media.

2. Use the values imagined for L/HCyl, BPT and Surfaces from above and
create a new drivetype in HDToolBox. Use this drivetype for the MO and
partition the medium. Save eyerything. Then reboot or use scsimounter, to
mount the MO-Medium. Format the partitions amigawise.

That's it. No magic.
It should work. At least it works here with an 128MO Drive from Olympus.

So long..
