Overview This document discusses secure erase options and hard disk security on HP FutureSmart Firmware printing devices. The section of the disk containing job data can now be securely erased on demand, instead of performing an entire disk wipe (See Erase Job Data). Industry standard ATA Secure Erase is an available option which securely wipes all data including spared and reallocated sectors for decommissioning devices (See Secure Disk Erase).

This erase mode is only accessible from the pre - boot menus for the main system disk. It is available for accessory disks in EWS and Web Jetadmin. If the erased disk contained the system firmware, performing an Erase/Unlock will render the device inoperable, and a new firmware image must be installed to the disk before the device can be used again. 1 Secure Erase 2 Erase / Unlock 3 Get Statuses Figure 5: Secure Disk Erase in device Pre - boot Menu 4.

The accessory drive can be securely erased independently of the system drive. Two erase operations are available.  If the drive is an HP Secure Disk encrypted hard drive, a cryptographic erase can be performed. (See the Erase / Unlock section in the Secure Erase section)  Secure Disk Erase selects the most secure method to remove the drives data, other than a cryptographic erase.

Disk Initialization Commands These commands reinitialize the hard disk or sections of the disk to provide troubleshooting and diagnostic capabilities. The commands are similar to disk formatting commands and do not provide sector level data overwrite. These erase command are not recommended for securely removing customer data. These commands are only accessible from the device pre - boot menus.  Clean Disk removes all data from the disk. This command will render the device inoperable.

Appendix A: Secure Erase Data Overwrite and Specifications Normally when a file is deleted from a HDD, the filename entry is erased from the disk’s file allocation table, removing the file’s presence. The file’s data still exists in the disk’s individual sectors and is overwritten only when that sector is allocated for a different file.
