So which is it? In one message, you're asking for a program that wipes all the free space on a drive and claim that wipe does this on Linux and that obliterate on FreeBSD just wipes files. Then, in the next message, you claim that wipe on Linux is a "secure file wiping utility" and that somehow the FreeBSD suggestions you've been given are inadequate. Huh? We've seen means posted of overwriting a single file or remaining disk space (by filling all free space with a dummy file containing garbage) with both /dev/zero and /dev/urandom, so doesn't that answer your question?
