If you are *that* concerned about securely wiping hard drives you should probably just physically destroy them. If you need more than /dev/zero can provide you are obviously concerned about people with physical access to the platters from reading old data, in which case you also have to take reallocated sectors into account, which you can't clean from the OS.
