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 • HP LaserJet 4100mfp, 4345mfp, 4730mfp, 9000mfp, 9000Lmfp, 9040mfp, 9050, 9050mfp, 9055mfp, 9065mfp • HP Color LaserJet 5550 printer • HP Color LaserJet 9500mfp 12
