I wanted to go through some older files for a project today and when I tried to navigate to them in Lightroom. I discovered that the contents of three of my external hard drives had been scrambled in the Lightroom Catalog. I use 4 external drives of which 1, 2, and 3 have various years on them and 4 is waiting to be used. All of a sudden, the contents of #2 were showing on 1 and 4 and the contents of #1 were showing on 2. All, of course were grayed out with ? after them to indicate that LR couldn’t find the files. I finally have most of it straightened out by going through each year and pointing LR to the proper location, but I’m unable to understand how it happened in the first place. I checked backup catalogs and the last three showed the same problem. I then went back to just before the last big LR update when they changed the catalog file system. Unfortunately, that was inconclusive because to use it it had to be converted to the new system, so now I’m totally confused.
Anyone have any ideas?
By the way, I discovered that when LR creates a backup catalog it never seems to get deleted. I have them going back to 2017, so I think I can free up some drive space.
