Maybe I didn't explain it well. I talked about the "real" formatting here, 
not what DOS/Win call "formatting". Sure, they have to be "real" formatted 
once in factory --> but not in his case in order to bring a filesystem 
onto them.

Mmm, perhaps. It's just wired because of those MS-guys calling "format" 
what we call "newfs".

Hehe ... you've ever seen a good working floppy, especially if it's ten
years old and the eight years old drive has never seen a floppy before?
