Upgraded LR4 to LR5. Installed a new external D-drive for photos for LR5. When I went to use my previous photos on a different D-drive, LR5 only recognizes 44 photos in one folder. I have over 3000 photos in folders by date on this LR4 D-drive that LR5 does not recognize even though the LR5 catalog says it has upgraded the LR4 catalog to current level.
I hate to lose all my develop data et cetera on these LR4 photos. I have backed up all the photos on the LR4 D-drive to another drive and know the photo is usable but would like to have the LR4 data tied to the particular photo.Help. Thanks.
I don't think anyone can help with correcting your catalog/catalogs as you have not provided a detailed enough explaination of what you did and when you did it.
As far as using the external drives, you should not use 2 external drives using the SAME drive letter with 1 catalog. You must assign each drive a different drive letter to prevent problems like you are seeing.
