The 'parameter' is the device name /dev/fd0f. 'man 4 fdc' tells me

  The driver supports the following floppy diskette formats by using par-
  ticular partitions:
  ...
  720KB  3.5-inch (f)
  ...

Using /dev/fd0b with DD floppy disks (just for a test) does not work at all,
every track is marked as defective (E). With /dev/fd0f only some of them
are marked and not the same ones every time I try.

I had no problems formatting DD disks with Windows as 720K disks.

Thanks for your help.
