CompTIA A+ Core 2 (220-1002) — Question 126

The medical records department of a local hospital recently upgraded its computers. A technician needs to ensure the data stored on the hard drives is unrecoverable. Which of the following methods should the technician use to meet the requirement?

Answer options

• A. Standard format
• B. Low-level format
• C. Overwrite
• D. Degauss

Correct answer: D

Explanation

Degaussing is the most effective method for making data on hard drives unrecoverable, as it disrupts the magnetic fields used to store data. In contrast, standard and low-level formatting, as well as overwriting, may not completely eliminate recoverable data, making them less secure options.
