i take alot of "personal" pics of my GF. then i put them onto the HD, then burn them over to a CD, then erase the pics left on my HD with a 35-pass. a friend of mine told me that Eraser is very good at erasing many things, but that it cannot erase pictures well, because pictures are "magnetically burned" onto the HD (i really don't remember exactly how he phrased, but that's not really the point). i told him that's he's wrong and Eraser can erase any files, jpg's, mpg's, txt's, it doesnt matter. so my question is, is he right about this at all? are the pics of my GF that i erase still left behind on my HD?
