What Others Think

This is in fact a useful command, and often used when giving away or scrapping computers. But doing this while the system runs from a partition on /dev/hda will probably lead to some sort of kernel panic, and the command will be interrupted before the whole disk is erased. I'd recommend running it from a bootable CD like Knoppix, or at least set the system into single user mode with "telinit 1" first. And yes, doing it only once should be enough, check out http://16systems.com/zero.php (The great zero challenge) for more info.
