Degaussing is the only data erasing method that can permanently destroy a magnetic-based hard disk by reducing or eliminating the magnetic field. Wiping and purging only delete the data, but the magnetic field remains intact. Data sanitation is a general term that includes various methods, but degaussing is the only one suitable for destroying magnetic media.
