How much wiping do you do? :)

One pass is enough?  Hmmm...anyone tell the DoD?  They still require
multi-pass wiping.
I sent a simular question to Scott Moulton, but I figured I'd ask in this
gorup as well. I always wondered if wiping with more than just all
zeros was
necessary, then I saw this:

and this

So, is it totally useless to wipe a drive more that once? What would
it take
to get the data off of a drive wiped once with all zeros?

Also as a side note, Scott sent me a link to this tool awhile back
that uses
some on board stuff of modern drives to wipe even sectors marked as bad by
the internal drive logic:


One more side note: Anyone know how I can wipe my slack space with an
arbitrary set of bits? I though it would be funny to but the
lemonparty jpg
all over my slack space for investigators to find :)

Thanks much,
