If there is a utility included in any of the Norton stuff which understands
the UFS/FFS filesystem layout format. You may be able to read the raw
disk, but you won't understand the filesystem.
From experience (on another platform), if the FS hooks are there to allow
easy (note: EASY) addition of new filesystem types into the OS, then adding
read-only UFS support isn't that much of a pain. I did it in a few weeks
part time coding, learning UFS from scratch in the process. However,
I've never tried adding filesystems to DOS and / or Windows, so I can't
comment on the availability of hooks for doing that. Judging by the
hurdles you have to hop through to mount Netware, etc, partitions under
DOS, my thought would be that it's not possible to do it under DOS, but
may be possible under some of the later MS offerings, like Win 95 or NT
perhaps.
