Gutmann notes that a great many standards for sanitizing classified media are themselves classified, and believes that the published standards may well do an inadequate job (on purpose). > writing AA, then 55, then FF Not nearly good enough (according to Gutmann); his work shows 35 passes are needed: four of random data, then 27 carefully-selected bit patterns to cover the (then-) known encodings methods, then four more random passes. Gutmann's work is now six years old, but his findings clearly indicate that recording density and encoding method play a large part in what is required to truly erase data -- which means even the 35 passes described above may not be sufficient today. If you don't want someone to read the data, destroy the media. Period. AdamM --- Send mail for the `bblisa' mailing list to `[EMAIL PROTECTED]'. Mail administrative requests to `[EMAIL PROTECTED]'.
