Ideally one should use /dev/urandom instead of /dev/zero but that would take couple of days to clear a 5-10GB partition with truely random data instead 5-10 minutes for /dev/zero. An intermediate could be creating a file of 1-2M with /dev/urandom and overwriting the partition with that data. The actual commands are left as an exercise to the reader. Of course replace the variables as required. And remember, these steps are highly destructive. Know before you do.
