My main EHD, 'Photo Files_4TB' is failing. I have revived it long enough to copy it to a new EHD, 'Photo Files_6TB'. There are almost four terabytes of photo files on the drive, including all the photos referenced by LRC. How do I change LRC so that it is referenced to the new drive instead of the old one which is no longer working? The new EHD has the exact same folder structure and file names as the old one that was referenced by LRC.
In the library module, right click on the top most folder(s) in the left-hand panel and choose the option to update the folder location. When Finder appears, browse to the folder on the new hard drive and choose it. Repeat that for each folder. If all of your folders are under one master folder then you will only have to do that for the one master folder.
