1 Enter the Configuration menu, and then navigate to:
Restore Factory Defaults > Erase Hard Disk
2 Select any of the following:
• Single Pass Erase overwrites all data and the file system. This wipe is faster but less secure since it is possible
to retrieve the deleted data with forensic data‑retrieval techniques.
• Multiple Pass Erase overwrites all data without rewriting the file system. This wipe is DoD 5220.22-M compliant
since the deleted data is irretrievable.
3 Apply the changes.
