Neither does "typo" appear to be the proper term for it. Rather it seems
your statement falls somewhere between nonsense and typographical error
into that vast, catch-all category sometimes referred to as "I misspoke."

 -I  It is typical for fixed disk devices to be partitioned so, by default, you are not permitted
     to  create  a filesystem across the entire device.  mkfs.fat will complain and tell you that
     it refuses to work.  This is different when using MO disks.  One doesn't always need  parti‐
     tions on MO disks.  The filesystem can go directly to the whole disk.  Under other OSes this
     is known as the 'superfloppy' format.  This switch will force mkfs.fat to work properly.

I think PH's inference not too arduous from the above, frankly.

But how about:

  -I When using MO disks, where partitions aren't always required, modifies
     mkfs.fat's default behavior, allowing it to write the filesystem across the
     entire, unpartitioned device (called 'superfloppy' format under some
     other OSes).
