Appendix B—HP Secure Erase
HP Secure Erase implements the Department of Defense (DoD) specification 5220-22m algorithm for
the deletion of data from hard disk storage. Typically when files are erased from a disk, they are simply
marked as removed, however the data remains on the drive and can be recovered with undelete tools.
The DoD 5220-22m algorithm specifies the repetitive overwriting of the disk data to ensure no trace
magnetic data remains. Data erased using the DoD 5220-22m algorithm is considered unrecoverable.
Secure Erase can occur continuously as files are deleted, or erase the entire disk when triggered by an
administrator or a regularly scheduled event configured by HP Web Jetadmin.
HP Secure Erase is available on the following devices:
• HP LaserJet 2400, 4250, 4350 printers
