use df or fdisk to figure out the size of the partition
then use
dd if=/dev/zero of=${DEVICE_NAME} bs=1024 count=${SIZE_OF_DEVICE}
where
DEVICE_NAME = the name of the partition (varies)
SIZE_OF_DEVICE = in 1k blocks
If you want to be truly paranoid you do this several times over
alternately substituting /dev/urandom and /dev/zero
Don;t do this to any partition that represents the entire disk
