DoD EraseComp Method:
**The erasing time of DoD Erase mode is 3 times longer than Full Erase mode,
and the time of DoD EraseComp is 4 times longer than Full Erase mode.
Note
**The erasing duration of DoD Erase mode is 3 times longer than full erase mode.
**The duration of DoD EraseComp is 4 times longer than full erase mode.
DoD Erase Settings for the third time: enter pattern of random characters in

Secure Erase (NIST800-88)
The international authorized high standard Secure Erase function. It overwrites every single
track on the hard drive with "00". Even HPA/DCO or other data area which are not able to load,
can be erased all together.
Caution
Highly recommended, please DO NOT disrupts Secure Erase during operation. Otherwise, it can
cause irretrievable error on HDD, which turns the HDD unusable. We are not held responsible
for any damages.
