Degaussing is a unique process for the permanent destruction of data on hard drives. During this process, the magnetic domains of the drives are deliberately destroyed, rendering all stored information completely unreadable. Specialized degaussing devices remove the magnetic coating made of chromium or iron oxide that is used to store data. By precisely altering the magnetic field, all information is made permanently inaccessible. Depending on the Oersted (Oe) rating of the drives, the device generates a controlled magnetic field that guarantees maximum security in data destruction.
