freebsd-dev/usr.sbin/fdformat/fdformat.c
Joerg Wunsch a5cef3b45a Now that we've got it, use FDOPT_NOERRLOG for fdformat and fdwrite to
avoid blasting the syslog with error messages from bad floppies.  Both
tools have their own error reporting anyway (which could easily be
cluttered by the syslog output on your terminal).
