Depends on the filesystem you're using, but you'd probably want to overwrite the hard drive several times. I was reading a magazine article in 2000 that said forensics people can read data from a hard drive that's been overwritten up to 9 times. Surely that number has gone up since then. (The 9, not the 2000.) But wouldn't the command drop out at some point (before completing) due to it or the kernel trying to access disk and finding trash? dd might even overwrite itself, if it's in swap. And then there's the whole waiting-for-random-data thing. "Please wait to crash in my door while I wiggle my mouse around." May as well make it /dev/zero. -todd -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
