I've heard a lot of good things about wipe. It's thorough. Which is what you want with a tool like this. Also it's packaged for Debian. sam@price:~$ apt-cache show wipe Package: wipe Priority: extra Section: utils Installed-Size: 124 Maintainer: Thomas Schoepf <[EMAIL PROTECTED]> Architecture: i386 Version: 0.16-7 Depends: libc6 (>= 2.2.4-4) Filename: pool/main/w/wipe/wipe_0.16-7_i386.deb Size: 30254 MD5sum: 7c1e53d1c7b2acb64aa33df8e00a1efa Description: Secure file deletion Recovery of supposedly erased data from magnetic media is easier than what many people would like to believe. A technique called Magnetic Force Microscopy (MFM) allows any moderately funded opponent to recover the last two or three layers of data written to disk. Wipe repeatedly writes special patterns to the files to be destroyed, using the fsync() call and/or the O_SYNC bit to force disk access.
