Major scrap in 2.5" Hard disk

1. Neodymium rare earth magnet
2. Aluminum casing
3. Aluminum - Platinum plated platter
4. Motor

Minor scraps in 2.5" Hard disk can be found on the circuit board

1. Copper pins
2. Tantalum capacitor -
3. Monolithic capacitor (Made of Palladium + Silver) -

That's all i guess for a small hard disk.
