You are being trained on the company’s process for the physical destruction of hard drives. The method used involves the use of magnetic fields to erase the data and render the drive unusable. What is this method of destruction called?
The answer is degaussing. Degaussing is the method of physical media destruction that exposes the drive to a very high magnetic field using a machine called a degausser. This erases all data on the hard drive and renders it unusable. Formatting is only a way to delete the data on the hard drive, while the other choices are all ways to physically render the drive unusable but not delete data.
