ls120 is treated as a floppy in terms of partitioning: none. You can
partition an ls120, but I don't think you can then read it on any other
OS.
zips use partition 4 because on macOS, the first three partitions are
reserved for system use, and macOS couldn't use PC-format disks without
the partition being 4. Don't know if MacOS x is smarter.

There's another thread about this now.

Not the same thing at all. IDE/ATAPI syjet (and sparq - the reason
syquest went under) uses the ide DISK driver, while ls120 and zip use the
ide FLOPPY driver, at least based on the internal ATAPI sparq drive I had
at one time. AFAIK SCSI doesn't differentiate the way the ATAPI standard
does.

Not halfway. We'd use partition 4 default on zips with fat FS because
that's the "industry standard" and you should be able to read or write one
on any OS/archetecture with native tools.
OTOH, the installer should check the case where the zip shows as "whole
disk" instead of partitioned, even though that seems to be something
screwy with BIOS.
