Hi humadon1,
Welcome to the Community!
When you said you are not able to see the second disk located in bay 2, do you mean the NAS cannot detect that disk or it the second disk does not sync with your existing volume?
If the NAS does not sync with your existing volume, what is the RAID configured on your NAS? Is it X-RAID or Flex-RAID? You can check this one by accessing https://<ReadyNAS IP address>, where <ReadyNAS IP address> is the local IP address of the NAS, then go to System> Volumes.
You may also provide us a screenshot of the Volumes tab.

John,
Everything seems to be working fine except for the second drive not showing.
When I go to System - volumes (see attached screenshot) I only see one drive.
When I run the RAIDar it shows two drives - see screen shot.
However, when I go in to the ReadyCLOUD I only see one drive

Your screenshot isn't showing the volume page. You need to log into the NAS admin UI (for instance by clicking on "admin" in RAIDar, or by browsing to https://10.1.10.252/admin
The volume page looks like this:
So log into the admin web ui and look at that page (selecting "system" in the top row, and "volume" in the second row).
But I think Sandshark is already pointing you in the right direction - and that what you are seeing is normal behavior.
First of all, there is a difference between a volume and a disk. With RAID, a volume usually is built from more than one disk. When you look at the volume page, I'm pretty sure you will see a screen shot similar to the one I posted above (except yours will show two 4 TB drives).
That is, you'll also see a single RAID-1 volume called "data". That volume is built from both your disks.
You'll notice that in my screenshot the capacity of the volume is 1 TB, even though the total of the disks is 2 TB. That is a result of RAID-1. The two disks are mirrored (everything written to one is written to the other). That protects my data if one disk fails.
First let's confirm that you are seeing a 4 TB RAID-1 volume on that page. Then we can talk through whether that is the right mode for you, and what options you have if it isn't the right mode.
