Lightroom import not seeing hard drive with changed drive letter

I installed a new hard drive, and mistakenly gave it the incorrect drive letter. I have now changed the drive letter, but Lightroom doesn't see the drive now in the "inport" dialog.

Windows sees the the drive just fine, and all files on it are prefectly accessible.  What can I do the convince Lightroom that the drive is there? Any ideas?

Windows 10.
