Which term describes the process of thoroughly and completely removing data from a storage medium so that file remnants cannot be recovered?

• A. Sanitization
• B. Destruction
• C. Certification
• D. Capacity planning

Answer: (A)

Data sanitization is the process of thoroughly removing data from a storage medium so that file remnants cannot be recovered. It covers techniques like clearing (overwriting with patterns), purging (stronger methods to prevent forensic recovery), and, when needed, destroying the media. The description matches sanitization because the emphasis is on ensuring no recoverable traces remain, not merely making the media unusable. Destruction can be part of sanitization but is specifically about rendering the media unusable, which is not always what’s required when the goal is to remove the data itself. Certification and capacity planning address compliance/validation and resource management, not data removal.
