HP Designjet Printers - Secure Disk Erase

HP Secure Disk Wipe
For more information about HP Web Jetadmin security plug-ins, see Questions and Answers later in
this paper.
The default disk erase mode is Non-Secure Fast Erase, and no file system access password is set. To set a
password and the secure disk erase mode, the administrator will choose the device(s) through the Device List
(double click on the device(s)) in HP Web Jetadmin (see Figure 1 earlier).
To set a system access password or select/change secure disk erase modes:
1. In the upper left of the window, choose “Configuration” from the drop-down list.
2. Click Security from the Configuration Categories list.
3. From here, administrators can:
• Type or change a new file system access password (type the password, confirm the password,
and then click Apply in the lower right corner).
• Select or change the file system erase mode (type the password, choose the desired erase mode,
and then click Apply in the lower right corner).
• Password and secure disk erase modes can be set or changed on multiple devices simultaneously
from the Device List page (select the devices, choose Configure under the Device Tools list, and
then scroll to the file system access password and erase mode).
7. Secure Disk Wipe
It is possible to force a Wipe of the Hard Disk with the currently selected level of Erase Mode (Fast Erase,
Secure Erase or Sanitize Erase). This can be done also through WebJetAdmin.
When a Secure Disk Wipe is forced, all partitions in the unit's hard drive containing user jobs and data will
be erased using the currently selected erase mode. The complete wipe will take approximately 45 minutes in
Fast Erase mode, 6 hours in Secure Erase mode and 40 hours in Sanitize Erase mode.
Once the disk has been completely wiped, the printer will reboot with an old firmware version, so we
recommend a firmware upgrade after the wipe.
8 Impact to Performance
The Disk Erase feature does not affect printing and typical copying including simplex, duplex, enlargements,
reductions, and n-up printing. Fast Erase is the fastest mode and is the default today. Secure Disk Erase is
slower than Fast Erase because the file data gets overwritten. Sanitizing Erase is the most secure mode, but
requires multiple overwrites of disk data and, therefore, results in the most impact to performance. Actual
performance impacts will vary.
