An organization is disposing of a number of laptop computers. Which of the following data
destruction methods would be the MOST effective?
Run a low-level data wipe utility on all hard drives
Erase all data file directories
Format all hard drives
Physical destruction of the hard drive
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.
