To remove all data from a drive and replace it with nothing do
dd if=/dev/zero of=/dev/<drive> bs=1M
You can append status=progress to the end to see how far it's going.
This also words on partitions, you just need to make sure it's selected.
dd if=/dev/urandom

Parition
This can be done with a number of utilities, such as parted and fdisk
