If you don't care about recovering dd (wikipedia has some examples) is a tool to do a block transfer utility so can be used to create copies of filesystems but also alter the one you are working with.
dd if=/dev/urandom of=/dev/{blockdevice} count={blockstowrite} bs={sizeofblocks} seek={wheretostart}
This bypasses the filesystem so will mess up the journaling. A bs=1k seek=10 count=4k will make the partition or disk unusable until repaired with e2fsck.
And I assume everyone knows it is a bad idea to do this on anything that contains something that needs to be saved 1st.
Oh it can be as simple as using a hexeditor to edit a bit on a raw device.
