Subject: When dd writes write-protected floppy (in 3.0R)
Sender: owner-freebsd-bugs@FreeBSD.ORG
Precedence: bulk
X-Loop: FreeBSD.org


Dear core team members,

    When I use dd to write a write-proteced floppy in FreeBSD 3.0 RELEASE,

    I can not stop the process by press Ctrl-C, Ctrl-Z, or "kill -9 dd-pid".

    Is this a bug?

    details:

        command: 

            dd if=picobsd.bin of=/dev/fd0  # but I forget to enable
                                           # the floppy writable

        error messages:
