Sorry, but all that is irrelevant to the problem at hand. He tried to
copy an image file, that includes the file system as a single file onto
a floppy disk that already contained a file system. He needed to use a
program that write that image file sector by sector onto a floppy disk.
And that way it will fit perfectly, no overformatting needed...

The problem with the general adaptation of 2.88MB floppy disks was that
those drives did have compatibility issues with reliably reading and
more so, WRITING 1.44MB disks...
