Only showing 1 hard drive in webmin

Hello everyone,

I’m running Ubuntu 18.04 on a server with 2 hard drives at 2 TB. Webmin only shows 1 hard drive on the dashboard. Under Partitions on Local Disks, it shows 2 hard drives, so that must mean they are both connected and working, but I do not know how to access/use the second hard drive? (Also not sure which one is currently in use) Any help is appreciated.
