A File System Password is no longer required for the Erase Customer Data operation. Also, the File
Erase Mode set under Configuration is only used for secure file erase of everyday temporary files.
For storage erase, an erase mode is passed as a parameter to the erase method. Instead of the user-
selected storage devices, the storage erase method will always erase all "customer data." To invoke
the service, a client with correct web credentials makes a call to Erase Customer Data passing a valid
erase mode. Internally, NVRAM flags are set and the device is rebooted.

The HP High Performance Secure Hard Disk supports a special erase referred to as a “Crypto Erase”.
The UI Storage tab contains a new Erase Disk button to be enabled for devices with the HP High
Performance Secure Hard Disk. The new button launches a new wizard giving the user the option to
select a disk from the list to erase. The button is only visible when a device that supports these new
features is selected.
Selecting the erase option for one of these disks forces its encryption keys to be destroyed and new
keys generated. This instantly renders all the encrypted data on the disk unreadable. There is no
method to recover the encryption keys and no method to recover the encrypted data once the keys
have been changed.
This erase mode is only accessible from the boot menus for the main system disk. It is available for
accessory disks in EWS and HP Web Jetadmin. If the erased disk contained the system firmware,
performing an erase will render the device inoperable. A new firmware image must be installed to
the disk before the device can be used again.
The Secure Erase Mode selection by the user is simply a desired choice. The device will make a best
effort attempt to perform the erase mode selected. If the selected option is not supported by the drive,
the device will perform the closest match to the user's selection.
