Replacement drive does not add to existing volume.
On our ReadyNAS 316, drive 5 failed and degraded the volume. I replaced it with the same 3TB drive. After adding the new drive, my only option was to destroy drive 5. Now the drive is black, with ...
It turned out the replacement drive I put in slot 5 was also bad. I took the original failed drive and removed all the partitions, then placed it in slot 5. Now it is rebuilding. I'll probably need to buy yet another 3TB drive though since the one there now has failed once. I did not run SMART on it.

Something is confused here. OS6 doesn't have the idea of destroying drives. You destroy/create volumes.
Now the drive is black, with a green light, but is not part of the existing volume. The volume is still degraded. Apparently the array is Flex-RAID and I must manually add the new drive 5.
You can switch to xraid easily enough.
But something seems wrong with your intitial comment. If you bought this after June 1 2014 then your NAS is entitled to lifetime chat support, so you may try contacting support (support.netgear.com).
It appears I can only create a new volume on drive 5, but have not tried it. I think when I first installed the new drive, it was formatted, so would only let me destroy it. Maybe it was considered a separate volume.
If the drive wasn't empty, then the NAS won't add it automatically to the array. Older NAS will, and that has cost several people their data (they assumed popping in an ntfs drive would just work). So Netgear added a manual confirmation for safety.
If you click on the new drive icon, do you see any options?
I only get an option for a new volume. I was thinking maybe I could create a new volume on drive 5, then somehow join it with the existing volume. Have tried it though. Or maybe I should remove drive 5, remove all partitions, then re-insert it.

That certainly won't work
...Or maybe I should remove drive 5, remove all partitions, then re-insert it.That is worth a try.
What is supposed to happen is that when you click on the unused drive an "add parity" button should appear in the volume box (underneath the pie chart).
I am wondering if this is a software bug (related to RAID-6 disk replacement). You should report it via support.netgear.com.
