CompTIA A+ Core 2 (220-1002) — Question 15

A technician is recycling PCs to be reused by a middle school.
Which of the following methods is MOST appropriate for ensuring data has been removed from the PCs?

Answer options

• A. Standard formatting
• B. HD drilling
• C. Low-level formatting
• D. HD partitioning

Correct answer: C

Explanation

Low-level formatting is the most effective method for completely erasing data from a hard drive, as it resets the drive to its original state, removing all existing data. Standard formatting and HD partitioning do not guarantee complete data removal, as they may leave remnants of the data accessible. HD drilling is a physical destruction method but is not practical for every situation.
