If I didn't misunderstand your question. If you're trying to write bits onto your disk so that nobody could recover data from it, there is a very simple way to blank out either YOUR WHOLE HARD DRIVE or AN ENTIRE SLICE ON YOUR HARD DRIVE. Using the `dd' utility you can write zero bits to an entire slice of your hard drive (or to the whole hard drive): dd if=/dev/zero of=/dev/<disk-or-slice-ID> Don't do this unless you want to lose all data on a slice or hard drive. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
