at first - it should be asked "can agencies recover your data without 
being overwritten" first.

just use geli(8)

then second problem is even less problem.

Finally use geli (or similar method) ALWAYS, no matter if you have highly 
important data, naked girls photos or just games. Just to say NO to 
any government agencies that terrorize you using your own money.

At least in Poland you are not required by law to provide any passwords. 
Encryption is legal.

At second - the basic claim that overwriting 1 with 1 differs from 
overwriting 0 with 1 at magnetization level is quite a proof of lack of 
understanding physics. Hint: magnetic hysteresis. What hard drive 
manufacturers want is to use magnetic material with largest hysteresis so 
difference between one and zero is highest.


Can all paranoid here finally put their hard drives to fire so they will 
heat over curie point, and then - end that offtopic?
