Explanation

Drive wiping is the specific process of overwriting every addressable storage location on a disk to prevent data recovery.

Common mistakes.

B. Spoofing is a deception technique where an attacker impersonates a trusted identity or source, not a disk data destruction method.
C. Sanitization is a broader term that encompasses multiple data destruction methods including wiping, degaussing, and physical destruction - it is not limited to overwriting alone.
D. Authentication is the process of verifying the identity of a user or system, which is completely unrelated to disk data destruction.
