I can navigate and add files in finder. I can check info, the weird thing is next to size it will say a size but then in parenthesis, it will say zero bytes on disk, even though the files are there.
The NAS is an 8TB NAS set-up to be 4TB redundant backup. So 4TB working drive, and 4TB copy.
Thanks so much for continuing to help!!!
I had problems with my NAS and other volumes after updating to Catalina. The new security features Apple rolled into Catalina are requiring changes to settings in your Security and Privacy System Preferences. This might be the problem with this volume. Can you check this... Go to System Preferences > Security and Privacy > Privacy > Select Files and Folders > in the right column under 'Allow the apps below to access files and folders > scroll to Lightroom and make sure that it is checked.
Then go back to the column on the left and select Full Disk Access and do the same... make sure that Lightroom has full disk access.
