I don't think anyone around here has got the _analog_ analysers and dsp 
stuff available to try to decode overwritten data!

One pass with /dev/zero or /dev/urandom should be enough. Two passes if 
you're paranoid and have got the time!! Ten or more times to get the 
FBI/CIA/GCHQ suspicious...


A single disk distro and dd should be easy enough. The hard part will be 
lugging the things to get plugged up for power/monitor/keyboard.
