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.
