How do I? Steps to perform
Secure Disk Erase
To protect deleted data on the product hard drive from
unauthorized access, use the Secure Disk Erase feature
in the HP Web Jetadmin software. This feature can
securely erase print jobs from the hard drive.
Data affected (covered) by the Secure Disk Erase feature
includes temporary files that are created during the print
process, stored jobs, proof and hold jobs, disk-based
fonts, disk-based macros (forms), address books, and HP
and third-party applications.
NOTE: Stored jobs will be securely overwritten only when
they have been deleted through the RETRIEVE JOB
menu on the product after the appropriate erase mode
has been set.
This feature will not impact data that is stored on flash-
based product non-volatile RAM (NVRAM) that is used to
store default settings, page counts, and similar data. This
feature does not affect data that is stored on a system
RAM disk (if one is used). This feature does not impact
data that is stored on the flash-based system boot RAM.
Changing the Secure Disk Erase mode does not overwrite
previous data on the disk, nor does it immediately perform
a full-disk sanitization. Changing the Secure Disk Erase
mode changes how the product cleans up temporary data
for jobs after the erase mode has been changed.
• Non-Secure Fast Erase. This is a simple file-table
erase function. Access to the file is removed, but
actual data is retained on the disk until it is overwritten
by subsequent data-storage operations. This is the
fastest mode. Non-Secure Fast Erase is the default
erase mode.
• Secure Fast Erase. Access to the file is removed, and
the data is overwritten with a fixed identical character
pattern. This is slower than Non-Secure Fast Erase,
but all data is overwritten. Secure Fast Erase meets
the U.S. Department of Defense 5220-22.M
requirements for the clearing of disk media.
• Secure Sanitizing Erase. This level is similar to the
Secure Fast Erase mode. In addition, data is
repetitively overwritten by using an algorithm that
prevents any residual data persistence. This mode will
impact performance. Secure Sanitizing Erase meets
the U.S. Department of Defense 5220-22.M
requirements for the sanitization of disk media.
