Shred is really all you need, and is readily available on (most?) live CDs.
There's no need to download/burn anything special for the occasion, since
you probably already have everything you need.

Shred default is 25 passes of various bit-sequences designed to foil
specialized equipment that is capable of recovering previous data from
zero-overwrite wipes.

If you just need to foil Joe Casual, a single zero wipe with progress will
be shred -v -z -n 0 /dev/yourblockdevice.
