there is a reason cryptologic facilities keep a small sledge hammer, a crowbar, and a blender/shredder in each "closed area"..
ONLY physical destruction of the the drive will keep prying eyes from seeing what is on it... Trust me...
Our drives are the "pull out" type.. With a little handle...
hmm, I'm new here so please bear with me...
I tried colonics .. Very uncomfortable, and awkward..
After talking to my family doctor he advised psyllium fiber powder, lots of veggies, and an occasional emema.. (man those are not too much fun..)
But it helps..
