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. The method will either be a Secure Erase using data overwrite or an ATA

Disk Architecture
The printing device Hard Disk is divided into different sections for different classes of data
 Job Data: Contains all job data, including temporary files for print and scan jobs, and Stored Jobs.
 Configuration Data: Contains printing device dependant configuration settings and system
information. Information stored here includes printing defaults, authentication configuration, and
some customer specific configuration settings.
 System Data: Contains the HP FutureSmart Firmware operating system code. This code must be
present on the hard disk for the printing device to boot. Previous HP printing device operating
systems booted from a compressed image stored in non-volatile memory.
 Repository: This area contains a compressed copy of the device operating system installation code,
providing a way to restore a corrupted operating system image or recover from a failed firmware
upgrade.
