If you want to fully wipe the disks of any data to start with, you can use a tool like dd
to zero the disks. First you need to figure out what your dive is enumerated as, then you wipe it like so:
sudo dd if=/dev/zero of=/dev/sdX
From there, you need to decide if you’re going to use them individually or as a pool.
