I have an ANSI standard dealing with protection of financial information that includes some amusing specifications.
Acceptable alternatives for handling magnetic disks that have failed in such a way that they cannot be overwritten with zeroes include wiping the surfaces at least three times with a permanent magnet, or: "Alternate procedures: a) Apply an emery wheel or sander to the recording surface of an inoperative disk. Ensure that the entire surface is completely removed prior to disposal. b) The resin binder and ferric oxide surface can be completely removed/stripped (chemically destroyed) from the disk with concentrated hydrochloric acid (55-58%). c) Melting." Mag tapes are even better, they are to be zeroed *and* "Before release of a zeroized magnetic tape, it should be subjected to two degaussing cycles and removed from the reel, then destroyed by disintegration into pieces 9mm or smaller, or incineration." Finally, paper. "Paper materials should be destroyed by burning, pulverizing, or cross-cut shredding. When material is pulverized, all residue should be reduced to pieces 5mm or smaller. When material is burned, the residue should be reduced to white ash." The Globe definitely fell short of ANSI X9 standards... -Bruce McCulley ---- Original message ---- >Date: Thu, 2 Feb 2006 12:30:37 -0500 >From: Tom Buskey <[EMAIL PROTECTED]> >Subject: Re: Information security, recycling and irony >To: GNHLUG User Group <gnhlug-discuss@mail.gnhlug.org> > > So, to bring it back to topic, how do people go > about removing data from computers? > > I have to deal with DOD stuff and there are some > approved disk scrubbers.
