Degaussing (Disk Degaussing)

Degaussing is a data destruction process that involves demagnetizing a magnetic storage media, such as a hard disk drive, to erase the data it contains. This technique uses a device called a degausser to generate a powerful magnetic field that disrupts the magnetic domains on the disk, which are used to store data. By neutralizing these magnetic fields, all information stored on the disk is permanently obliterated, making recovery impossible.

Considerations:

Importance: Degaussing is a critical step for organizations that handle sensitive or classified information, ensuring that decommissioned magnetic media do not become a security risk. It is a preferred method for meeting strict data destruction policies and regulations.
