4. Erasing

Erasing is similar to overwriting, but it goes a step further by providing a certificate of destruction. This certification verifies that the data has been completely erased and cannot be recovered. Erasing is a reliable method that offers peace of mind when it comes to safeguarding sensitive information.

5. Degaussing

Degaussing is a data destruction method commonly used on magnetic media. It utilizes a high-powered magnet to eliminate the magnetic properties of the media, rendering the data unrecoverable. This method provides an effective solution for secure destruction of magnetic drives and tapes.

6. Physical Destruction

Physical destruction methods involve physically crushing, disintegrating, or shredding the media, ensuring complete destruction. This method is particularly useful for devices that cannot be wiped or degaussed effectively. It guarantees that the information is irretrievable, making it one of the most secure methods of data destruction.

Here is a comprehensive table comparing the different types of data destruction methods:

Advantages Limitations
Deleting/Reformatting Hides data from the user Data can still be recovered
Wiping Allows for media reuse Requires proper techniques for complete data obliteration
