Smaller drives don't seem to have enough value to be marketable anymore. The scrap place I was at the other day was sorting drives, all tested bad from some rma type place, and anything smaller than 3 GB was going in a gaylord (heavy corrigated paper box that just fits on a pallet). It was almost completely filled by the end of the day, and that is one heck of a lot of drives, a rough guess is about 4,000, so it must have weighed more than a ton.
