Format a USB disk on PURE FAT32, one partition only, on a Mac

Question

There are other questions on SO about this, but not asking what I want.

I do not want to know how to format an external FAT32 disk from terminal, because this can be done by typing this:

sudo diskutil eraseDisk FAT32 MYDISK MBRFormat /dev/disk2

but this is the problem.

A disk formatted using this will be shown on disk util like this:

/dev/disk2 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *2.0 TB     disk2
   1:                 DOS_FAT_32 MYDISK                  2.0 TB     disk2s1

a real disk formatted by windows will appear like this

/dev/disk11 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:                            IOMEGA                 *1.0 TB     disk11

see that the Mac version has 2 partitions.

I have tried using exFAT instead of FAT32, on that command line. No change.

I am having problems using that Mac formatted disk as a shared disk on a router and the windows version works fine.

The problem is that I don't have windows anymore. This windows formatted disk I have was formatted years ago.

How do I do that?
