It's not clear waht you are trying to do. Do you want to make sure
none of the old data can be recovered from the partition, or do you
just want the partition to contain an empty filesystem?

If you want to make sure no data is recoverable, then run 'wipe' on
the parition. If you just want an empty filesystem then just run
'mkfs -t<whatever>' on the partition.
