[1] Yep dban is what I used to wipe all the branch servers and workstations from NAB a few years back, never had any issues with it 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. apologies to luv-main; Rohan McLeod
