Copy or transfer from PR2100 through USB to 16TB WD HD

I have a PR2100 with 2 2TB drives set up as spanning that I’m wanting to transfer to a new 16 TB drive.

I bought a SATA to USB adapter and plugged the 16 TB HDD into the front of the PR2100, but can’t access it. I downloaded some of the available apps hoping to be able to format the thing and start transferring.

Could anyone here could steer me in the right direction?

Thank You for your time!
