Part 3: How to Erase a Hard Drive with a Degausser

Since hard drives are essentially a magnetic storage, they can be altered by using a degausser. It is the process of eliminating (or diminishing) data that is stored on a magnetic disk (like hard drives). After performing degaussing, you are guaranteed to completely wipe your hard drive. By using the right kind of degausser, you would be able to wipe your data entirely without the scope of recovery.

In a nutshell, it is a process of demagnetizing a drive by using controlled magnetic files (through a degausser). You might already know that hard drives store data in binary format (0 and 1). 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.
