Secure Disk Erase provides three different levels of security:
●
Non-Secure Fast Erase: all pointers to the information are erased. The information itself remains
on the hard disk until the disk space it occupies is needed for other purposes, and it is then
overwritten. While it remains on the disk, it is difficult for most people to access, but may be
accessed using software designed for the purpose. This is the normal method in which files are
erased on most computer systems; it is the fastest method but the least secure.
●
Secure Fast Erase: all pointers to the information are erased, and the information itself is also
overwritten with a fixed character pattern. This method is slower than Non-Secure Fast Erase, but
more secure. It may still be possible to access fragments of the erased information by using special
tools to detect residual magnetic traces.
●
Secure Sanitizing Erase: all pointers to the information are erased, and the information itself is
repetitively overwritten using an algorithm designed to eliminate any residual traces. This is the
slowest method, but the most secure. Secure Sanitizing Erase meets the US Department of
Defense 5220-22.m requirements for clearing and sanitization of disk media. This is the default
security level when using Secure Disk Erase.
Secure Disk Erase is one of the facilities provided by Web JetAdmin, which is HP's free Web-based
print management software: s

Before choosing to erase the whole hard disk, you should be aware of the following considerations:
●
You may be asked to restart the printer several times during the process, which will take about 6
hours with Secure Disk Erase or 24 hours with Secure Sanitizing Erase.
●
The demo prints available from the front panel will be deleted and not restored.
