After overwriting the data once with random data, the drive itself (without tampering) won't reveal any of it (otherwise, it would not be able to hold any data after being written once). If the data that was once on the disk requires you to spend more effort on it (to ward off more sophisticated methods of data recovery), scrap the thing and buy a new one. Even at the hourly wage of someone flipping burgers, you will quickly spend more than a second-hand 120GB USB disk is worth.
Yes, note that the NMR scanner proposal was not a serious one. The best way not to have such problems is to encrypt all data _by default_, and just destroy the keys needed to decrypt before giving the media away. This way, the data is reasonably secure (very secure, actually), and you can spare the media, too. -- Jure Koren, n.i.
