HP Designjet Printers - Secure Disk Erase

HP Secure Disk Erase
b. Each byte of file data uses a unique random character from the buffer.
c. The random character buffer is reused up to 32 times, and then regenerated using new
random data.
4. To ensure successful completion of the write operation, each overwritten byte is verified.
5 Common Usage Environment
The most common scenario under which administrators will use Sanitized Erase or Secure Erase modes is
when devices are being used in a highly secure environment. The administrator will want to configure the
printer for Sanitized Erase or Secure Erase mode so that data is overwritten on an ongoing basis when data
is deleted from the disk.
6 User Interface
Administrators interface with the secure disk erase feature from the Device List in HP Web Jetadmin (Figure 1).
