Disk Wipe DoD 5220.22’M
The purpose of this Service Utility is to erase data from the Hard Disk securely, according to the
directive DoD 5220.22-M.
The printer's hard disk is used as a temporary storage area for print jobs. The Secure Disk Erase facility
can completely erase your information from the hard disk to protect it from unauthorized access.
Secure Disk Erase provides three different levels of security:
●
Insecure Mode: 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. This is the default security level when
using Secure Disk Erase.
●
1-Pass Mode: All pointers to the information are erased, and the information itself is also
overwritten with a fixed character pattern. This method is slower than Insecure Mode, but more
secure. It may still be possible to access fragments of the erased information by using special tools
to detect residual magnetic traces.
●
5-Pass Mode: 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. 5-Pass Mode meets the US Department of Defense 5220-22.m
requirements for clearing and sanitization of disk media.
