Most Secure: This method of securely erasing a volume or disk meets the requirements of the U.S.

It writes two passes of random data to the volume or disk and then writes a single pass of a known data pattern to the volume or disk.

Three-Pass: This is a DOE-compliant three-pass secure erase.

Advanced recovery techniques could restore the data, but it would require a great deal of time and effort.

Zero Out the Data: This erase method writes a single path of zeros to all locations on the selected volume or disk.

It doesn't scramble the file data, which means a recovery app may be able to resurrect the erased data.

It removes the volume's catalog directory but leaves the actual data intact.

Don’t Erase Data: This method is quick but not secure.
