Thank you! Section 9.3 of your tutorial helped! Everything that should have happened, happened!OK...
It looks like the drive is present but has no partition table and, consequently, no partitions. Any data previously on the drive is lost barring the use of data recovery tools that operate at very low level.
You need to create a partition table and at least one partition. See section 9.3 of my NAS guide linked to above.
