I am using LR 5.7 on an IMAC running 10.9.5. I an upgrading my external hard drive dedicated to LR to a larger capacity drive. I copied all the files onto the new drive. When I attempted to open the new drive in Lightroom it only showed the old drive that is now disconnected with all the files but no images. I uploaded one image from the new external drive, but when I opened it was the original file not the adjusted file. Seems like the metadata is not transferring. All I want to do is to transfer all the files to the new drive to use as the new dedicated drive for LR..
