Answer:
The correct answer is:
Degauss media with a magnet
Using a strong magnet to degauss (erase) magnetic media is a legitimate method. This process involves applying a strong magnetic field to the storage medium, effectively erasing the data stored on it. However, it's important to note that the DoD 5220.22-M method refers to a specific data sanitization standard set by the U.S. Department of Defense, and it doesn't specifically involve degaussing with a magnet. So, option 1 (DoD 5220.22-M method) is not directly related to using a magnet for degaussing.
Therefore, the most accurate choice is option 2.
Explanation:
The method that should be used to degauss media with a magnet is option 2) Degauss media with a magnet.
Degaussing is the process of erasing or neutralizing the magnetic fields on magnetic media, such as hard drives, tapes, or floppy disks, rendering the data unreadable. It is commonly used to securely dispose of or recycle media containing sensitive information.
When degaussing media with a magnet, a strong magnetic field is applied to the media, effectively demagnetizing it and removing any data stored on it. This process ensures that the information cannot be recovered or accessed.
It's important to note that not all magnets are suitable for degaussing media. Specialized degaussing equipment is designed to generate a strong and consistent magnetic field for effective erasure. Using an ordinary magnet, such as those found in everyday objects, may not provide the required strength or uniformity for reliable data destruction.
Therefore, the recommended method for degaussing media with a magnet is to use specialized degaussing equipment designed for this purpose.
