4.1 Quick Erase
This function will ONLY erase the index of the HDD. It is the quickest way to
erase the HDD.
4.2 Full Erase
This function will erase the whole sectors on the target HDD. It will take longer
than quick erase. Complies with NIST800-88 Standards.
4.3 DoD Erase
This function complies with the U.S.A. Department of Defense (DoD5220.22-M)
standard to fully erase the HDD three times bit by bit to overwrite HDD data
and guarantees data will not be recoverable. This DoD erase method will erase
HDD over each sector three times: the first time with zeros (0x00), second time
with FF (0xFF) and the third time with random characters.
4.4 DoD Erase & Compare
Besides DoD erase 3 times, this function will also execute comparison to make
sure the random bit is correctly written.
