CompTIA A+ Core 2 (220-1102) — Question 16

A company wants to remove information from past users' hard drives in order to reuse the hard drives. Which of the following is the MOST secure method?

Answer options

• A. Reinstalling Windows
• B. Performing a quick format
• C. Using disk-wiping software
• D. Deleting all files from command-line interface:

Correct answer: C

Explanation

Using disk-wiping software is the most secure method because it ensures that all data is overwritten multiple times, making recovery nearly impossible. Reinstalling Windows and performing a quick format do not effectively remove all data, and simply deleting files via the command-line interface may leave recoverable remnants on the drive.
