Description dvditto 1999-08-05 05:40:01 UTC 
When I use the raw write program you supplied with your boot images it actually creates bad sectors on my floppy disk.  When I use annoter version of raw write with you boot images, raw write stops part way though and reports that there is a bad sector, however there is aren't any bad boot on the disk.

The suggested utility for use with floppy images is fdimage.exe, which 
is also supplied on CD-ROMs, and is available at FreeBSD mirror sites.

How did you verify that the floppy is ok? Did you try another floppy?

It is impossible for a normal utility to create bad blocks on a floppy.
If you want to check whether you have bad blocks try the following
command:

	dd if=/dev/rfd0 of=/dev/null bs=1024 count=1440

That should produce an error on reading the floppy.
