In Maximum security mode, one can not unlock the disk without knowing the passwords. One way to reuse the disk is to issue the SECURITY ERASE PREPARE command followed by SECURITY ERASE UNIT.

A person can always use Truecypt using two layer encryption with a long password which IMHO would be unbreakable.
