My two computers running FreeBSD 9 can't even fdformat the floppy.  The 
format utility runs and marks all tracks bad.  If I abort the process, the 
computer panics.  I always fdformat a floppy before running DD because I find 
that DOS fomatting of the disk does not catch all of the surface errors.

The floppy disks that were marked bad by FreeBSD 9 were successfully 
formatted by my laptop that runs OpenBSD 5.  I was able to successfully DD 
the image from CDROM to the 'bad' floppy disk from the laptop.
