An organization is disposing of a number of laptop computers. Which of the following data
destruction methods would be the MOST effective?

A.
Run a low-level data wipe utility on all hard drives

B.
Erase all data file directories

C.
Format all hard drives

D.
Physical destruction of the hard drive

Explanation:
The most effective method is physical destruction. Running a low-level data wipe utility may leave
some residual data that could be recovered; erasing data directories and formatting hard drives are
easily reversed, exposing all data on the drive to unauthorized individuals.
