4.2 Purging Data (Level 2 - Most Secure)

With highly confidential data it is recommended that after cleaning the device with a software-based tool, users should also use some sort of degaussing machine to give the device another layer of sanitization to ensure all data has been cleared. If this is not possible, it is recommended that they do the initial sanitization phase again.
