I use a Win98 floppy and boot from that, then use fdisk /mbr and then
use fdisk to remove all partitions.  Then create a DOS partition the
maximum size of the drive, format it.  Reboot from the floppy after
doing every step.  The long way around but it works for me.

You might just check with fdisk what it sees as partitions on the drive,
you may still have a small partition for FC4 (non DOS) by booting from
the floppy only.
