In traditional boxes, no amount of overwrites can guarantee that the whole
track path has been overwritten so that residual information at the edges of
the track cannot be picked read by some low level diagnostic tool.
The only utility that can guarantee this is:

Or a hard drive shredder, like this one:

(Just the first one I found from a Google search.)
I was looking for different one that I thought I recalled reading about,
which reduces HDDs to something like .045" particles (about the size of
a grain of sand) in one pass, but I couldn't find it quickly.
I recently spoke with one customer that has such a shredder, though I do
not know what kind or how small the output bits are.
