Description
Secure Erase is a process for securely deleting data that follows standards developed by the Defense Security Service (DSS). These standards were developed to solve the problem of secure and permanent removal of data, and this capability is now used by many commercial enterprises. These standards require multiple passes to erase data. In the process of erasing, the system overwrites data with zeros, a random pattern of data, or ones (1s) to make the original contents unreadable.
In the DR Series system, two modes of secure erase have been adopted: 3-pass and 7-pass standards. This command securely erases all data with a 3-pass or 7-pass mode and runs during system initialization. This command erases all of the stored data while keeping the system in tact.
Syntax
system --init --secure_erase 3-passes system --init --secure_erase 1-pass system --init --secure_erase 7-passes
