It has a circular platter with a metal coating. As the platter spins, it lets the read/write head to perform the needed operation. Data is written through the head by passing pulses of electricity.

This magnetizes the surface of the platter. When a degausser is passed through the hard drive, it generates a powerful magnetic field. This permanently removes the magnetic properties of the drive, making it completely inaccessible in nature. The earlier recorded data pattern now becomes randomized and impossible to retrieve.
