On most filesystems (not on btrfs, for example), "dd if=/dev/zero of=somefile bs=1M ; rm somefile" (as root) will happily zero all the data area in the filesystem that hosts somefile (provided it is otherwise idle). Zeroing stale metadata areas is filesystem-version-specific, dangerous, and not worth the effort. -- "One disk to rule them all, One disk to find them.
