The german PC magazine c't has sent in hard disks overwritten once with
zeros to data recovery firms. No data was recovered. So unless your
opponent has secret service connections I'd say you are safe. He will
rather watch your screen or log your keystrokes than mess with the hd - if
he's not already in your WLAN that is.
