Step 3: Salvage the Magnet.
Sorry I dont have pictures for the steps on how to extract the magnets.
1. Get the old harddrive and remove the screws from the casing.
2. Locate the magnets and unscrew them from the casing.
3. Use pliers to hold the piece of metal attached to the magnet, the magnets have some kind of glue holding them down, adding to amazing strength these little things have.
4. What you want to do is bend in two directions so that the magnet comes off the base.
