Whilst it does state:
"...DBAN prevents all known techniques of hard disk forensic analysis.
It does not provide users with a proof of erasure, such as an
audit-ready erasure report."
From memory the consensus at ComputerBank many years ago was
that if one's life was on the line and NSA wanted the info;
dismantle the drive and dissolve the drive platters carefully in
in a large quantity of molten aluminium..
Apparently the problem is that the magnetic domains which
represent bits are analogue.
So whilst the heads on the original drive can detect no magnetic domain;
someone with a souped up head might be able to.
Initially the method we used wrote zero's to all sectors but
eventually to speed things up I think we ether used a generic LLformat
utility
and /or proprietary utilities from the respective drive manufacturers;
probably via a self booting DOS floppy.
