Damn, what kind of national secrets are you keeping??

I run DBan, and any of the medium passes should be more than sufficient. Drilling holes is overkill, but it will work too.
If someone really wants to go after your data even after you drill holes, do multi-passes, then you've got much much bigger problems than your HD losing data!!!!
Any of the Dban / multi-pass methods should be fine, and the drilling of holes can be done as well, but unless the hard drive is defective, why waste it?
