Which of the following methods is a way to superficially delete files on a hard drive?

The correct answer is A. Drilling. Drilling physically punctures the hard drive platter at specific points, but only damages localized areas of the disk. This makes it a 'superficial' destruction method because data stored on undamaged portions of the platters can potentially still be recovered using forensic tool

Explanation

Drilling physically punctures the hard drive platter at specific points, but only damages localized areas of the disk. This makes it a 'superficial' destruction method because data stored on undamaged portions of the platters can potentially still be recovered using forensic tools. In contrast, degaussing magnetically erases all data, wiping overwrites all sectors multiple times, shredding completely destroys the physical media, and low-level formatting rewrites sector data - all of which are more thorough and complete data sanitization methods. Drilling is considered the least secure because it does not guarantee full data destruction.
