How do different erase modes work?

Quick and secure erase functions

Quick erase and secure erase are functions the duplicators call on the hard drives themselves. How they work depends on the manufacturer of the hard drive.

Department of Defense erase function

A Department of Defense (DoD) erase is a function performed by the duplicator where it does three passes. The first pass writes all 0s. The second pass writes all 1s. The third pass writes 0s and 1s randomly.

Note: Not all duplicators will feature all of these erase modes. It is important to review the product manual to confirm the available erase modes.
