Secure Disk Erase provides three different levels of security:
Insecure Mode or 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.
1-Pass Mode or Level 1: 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/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.
5-Pass Mode or Level 5: 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; it meets the US Department of Defense
