Yes. NeXTstep does not have the software drivers to build new raw
DOS file systems. Except on floppy disks, where the file structure is
much simpler. What there is lives in /usr/filesystems.

I suppose that nowadays you could attach your SCSI MO drive to a Linux
system and build a DOS file system there. There is a software package
"dosfstools".

Reading through again, if you want to reformat a MO disk from DOS to
NeXT, what I remember as the magic recipe is first to format it as a
Macintosh file system. Then you can make a NeXT-format disk out of it.
