Not that I know of, but that's the beauty of (most things) Linux. mke2fs is part of the e2fsprogs package; adding a wipe-disk feature wouldn't be unreasonably complicated. Doing a half-dozen overwrites will slow things down by a healthy margin, but it could be done with relative ease. What's the "recommended" overwrite procedure? I have a vague memory of it involving writing 00 and FF and a few other things, and then some (pseudo)random data, and an equally vague memory of some DOD standard. I'll try to search for it later on if I stay awake that long. ...dave
