OK here is a bit more info.
I added the Disk Location plugin.
The two 16 TB Seagate drives (one is data and one is the parity) in the Not Found Section passed the SMART test, so they have power and they both have new SATA cables as well. However, they both don''t show up in the array (or as unassigned drives).
Any ideas on how to get them to appear? This is last issue from rebuilding. What I am I missing?
Thanks in advance.
