Your forgiven :)  The problem is not what file system the floppy has on it
but rather the track layout of the floppy.  The path to the device has
nothing to do with why you can or can not write msdos disks.

It would be fairly simple to update fd.c to do msdos disks if anyone
really wanted to.  Until that time however there is no way to write
an msdos disk.  No user-land binary has access to DMA or other hardware
required to write raw data to the floppy.
