I know, it is a strange question. But somehow it came to me and got me thinking. It is quite simple, if you take a 750GB (for example) and fill it to the brim with stuff, does it weigh more than it does empty? Even my a microscopic amount. I heard somewhere that data is simply electrons arranged inside the hard drive or something that, and if that were the case, it would weigh the same. But I'm just curious. Thoughts?
