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. The
device firmware must be re-installed to the disk before the device can be used again.

Partial Clean removes all data from the disk with the except the compressed operating system installation
code in the repository and initiates a reload of the device operation system.

Government Erase Standards
These devices follow comply with current US Government requirements for clearing confidential data from a
hard disk as specified in Updated DSS Clearing and Sanitization Matrix AS OF June 28, 2007 and NIST
Special Publication 800-88, Guidelines for Media Sanitation.
NIST 800-88 defines three levels of sanitization, from weakest to strongest:
Clear Overwrite all storage space one or more times
Purge Degauss the disk or execute the ATA Secure Erase command if the drive supports it (all hard
disks used by HP support this command)
Destroy Incinerate, crush, or chemically destroy the disk
