[ubuntu] No permission to access new (second) hard drive

Hello, I have a new Ubuntu 20.04.6LTS installation with two hard drives. The second hard drive appears in Files > Other Locations. When I select it it says Folder is Empty. So I tried to copy a folder to the second hard drive. I get "Error while copying. The folder cannot be copied because you do not have permission to create it in the destination." In files, I tried to create a folder on the new drive by right clicking. But the New Folder option is gray, unavailable. The New Folder option in the drop down menu from the Drive2 thing in the upper left of Files, is also gray and unavailable. I right clicked in the directory area and selected properties (for the second drive). Under permissions, all three boxes are grayed out, and it tells me "You are not the owner, so you cannot change these permissions." I looked this up on the internet and found that I probably need to use the chmod command. However, everything I found is about not being able to access a file, not about accessing the hard drive. I don't know how to use chmod so it fixes the drive, (or the partition).
Please tell me how to gain access to the second hard drive.

In case this helps, here is what I get when I use the df -h command:
