It's not a primary, it's a logical drive in the extended. Oh, BTW
I have discussed this somewhat in another list.

This is not so. Only if you choose to hide them. I have a primary
on my IDE and two primaries on my SCSI and DR-DOS sees them all.
The only one it can't see is the NTFS NT partition in the extended
partition which is the last logical drive in the system.
This was true in older versions of DOS because I tried it years
ago with M$/PC DOS 3.3.
