thanks all for the replies.
ok now can i conclude that even if i erase the HDD more than 7 times, i can still recover some data by expensive techniques outside of software?
if that's the case, i might as well throw it into the incinerator ... :-)
( assuming i don't care about money factor and the HDD contains top secret data..example)

I don't recall the specifics, but there are certain US DOD requirements that include burning the platters with caustic substances (read: acid, torch, etc.) and physically marring the surfaces (read: hammer, grinder, sand-blaster etc.) I can't speak definitively about these, but I know there are requirements that include physical alteration of the media to render it harder to recover data.
Anyone have more details? Do we really need anymore?
