CISSP Exam Preparation (Question 248)

(248) Which is NOT a recommended way to dispose of unwanted used data media?

A. Copying new data over existing data on diskettes
B. Formatting diskettes seven or more times
C. Shredding paper reports by cleared personnel
D. Destroying CD-ROMs

The correct answer is copying new data over existing data on
diskettes. While this method might overwrite the older files, if the new data file is smaller than the older data file, recoverable data might exist past the file end marker of the new file.
