Secure Disk Erase

You might need to protect deleted data from unauthorized access on the printer hard drive. Secure Disk Erase is a security feature that you can use to securely erase print jobs from the hard drive.

Security levels are set by using HP Web Jetadmin. Three levels of Secure Disk Erase are available:

●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.

Affected data

Data affected (covered) by the Secure Disk Erase feature includes temporary files that are created during the print and copying process, stored jobs, proof and hold jobs, disk-based fonts, and disk-based macros (forms). Note that stored jobs will only be securely overwritten when they have been deleted through the Retrieve Job menu on the device after the appropriate erase mode has been set. (See Deleting a stored job.) This feature will not impact data that is stored on flash-based printer non-volatile RAM (NVRAM) that retains default printer 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 printer cleans up temporary data for jobs after the erase mode has been changed.

Gaining access to Secure Disk Erase
