And you shouldn't see that drive in the LrC folders panel.
LrC is NOT a File Manager program like Windows File Explorer or Apple Mac Finder or Adobe Bridge or any other File Manager program.
It is a Database program.
The only way to have LrC show a drive and folders it to Import images from that drive.
In your case If all your images are on that new drive, In the Same Folders they are/were in on the older drive and that new drive is either using the same drive lettter, Windows, or Drive Name, Mac, then all your images should show up as accessible and in the same folders they were in on the old drive.
Pleas look at this link. It is for moving from one computer to another but as far as the changing drives on the same comp,uter it is basically the same.
