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.

When I got my 68040 Cube upgrade kit it came with
a motherboard and an
OD of NeXTstep 2.0, and a NeXT SIMM-puller tool. And some instructions
about the sequence in which to change things. All this information is
coming out of my occasionally fallible memory. But I'm sure that I was
using NS 2.0 and 2.1 long before I had a CD reader.
Thanks for correcting me on that. Unfortunately, I've still
not gotten NS 3.3 to reformat the DOS-formatted MO disks in my
Pinnacle Sierra, even with the disktab entries that James provided.
It appears to read them fine, as well as writing small text files to
them, but it won't initialize them either from the Worksapce or a
shell.

Actually it reformatted the DOS 512byte/sec MO disk as a Mac
disk from the Workspace without any problem and immediately mounted
it as well. I then tried to reformat it as a NeXT disk from the
Workspace and it failed. I then dropped to a shell and told it to
initialize and format the disk and it went through all the motions,
showing that it completed, but it didn't mount it. I then told it to
eject the disk and I re-inserted it....the system then said that the
disk wasn't readable and asked if I wanted to initialize it.

New subject: Dealers of Lightning - Zerox PARC ...
I took a visit over to one of the thrift stores and found "Dealers of
Lightning", the history of Xerox PARC. It is a fairly new book (c 1999)
but looks to be pretty interesting. A search on ABE showed one available
at about $3.50 while most of the others were prices from about $10.00
up. Seems like a worthwhile book for the library.
