Lightroom not showing files on an external drive, was in the catalog
1st the basics, Lightroom CC and macOS Sierra, all at the latest version.
I was running LR and had pictures stored on an external drive as well as the internal drive. They were all showing in the catalog and I was able to access the pictures on the external drive from within LR. The external drive was ejected properly but when I reconnected the drive LR is seeing the drive and the folders but not the files in the folders. All the folders are showing zero as the size. The bar that has the drives name is shoring that space is occupied.
I am also able to go to the drive in Finder and see all the pictures. If I select Synchronize on the folder LR says no photos in previous import. I'm able to open the files in photoshop. Ejected the drive and reconnect it and the photos are still not shown.
I am seeing a folder called Lightroom1 with the files and folder listed but they all have a ? and the LED is grayed out while I'm seeing a folder called Lightroom with the LED green. If I right click on the folders in Lightroom 1, with the ? and select find missing folders it will import them to the Lightroom folder.
Confused, and please help.
