No need to remove any disks. When you run the command, you pass it a
list of the disks you wish to sanitize.

e.g. disk sanitize start 0a.16 0b.23

This will sanitize disks 0a.16 and 0b.23 using the default hex pattern
of 0x55 0xAA 0x3c. This will result in those disks being overwritten 3
times, once for each pattern. To be in compliance with DoD and DoE
requirments, you have to overwrite at least 6 times.
