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 (The great zero challenge) for more info.
