Failed harddrives have an "X" marked on them. The circuit boards are to be removed before the harddrive bodies are physically crushed.
- Laptop harddrives often need a tiny phillips screwdriver in addition to the torx sizes 5.5, 6 and 7.
- Regular harddrives most often need small to medium phillips screwdrivers, the occasional standard flathead, and torx sizes 7, 8, 9, and 10.
- First, any plates, rails, mountings, or other external metal parts are removed. Plastic parts may be used in harddrives, and are also separated. Screws are simply collected in a container and are recycled for general metals extraction later.
- Secondly, any circuit board, small or large, is to be removed and separated for further recycling. The circuit boards may have several small screws which are removed, and perhaps a multi-connector or two which are also unplugged. The boards are collected together for additional processing.
- Thirdly, after metal and plastic parts are removed, circuit boards separated, the harddrive bodies are physically destroyed by crushing. The crushing method is not critical, but it ought to be complete, with only twisted metal parts and shards of harddrive platters remaining.
