In my educated opinion, dban or dd is good enough even when
considering 3 letter agency guys.

NIST officially says a single pass against confidential data is
sufficient if the drive is 20GB or larger.  Older / smaller drives are
less dense and they still require multiple passes for that.

If NIST knew that 3 letter agencies could get around a single pass
wipe, then they would not have that official position IMHO.
