Got a new PC and am preparing to get rid of the old one. I need to clear the HD of everything before I give the machine to a charity of send it for recycling. How can I do this? Tried formatting it, but it is, of course, still in use by Windows ME. Tried from DOS prompt, but with same effect. Short of extracting the Hd and using my sledge hammer, is there a way of destroying all the data, please?
