Chris is looking for things to do with 20 old hard drives “I have twenty 3.5 inch hard drives collecting dust in my garage (10Gb and all working) and I will use them to do things. What things I haven’t decided yet, but I already have a couple of ideas. We have 20 nice shiny discs, as many read/write heads complete with arm, 40 very powerful magnets, and so on. It’s actually only the imagination that sets the limits. In this first part we go through the, maybe trivial but vital, task of taking the drive apart in its components without damaging anything.” Link.
