Are there any '?' on the folders in the library and/or '!' on the images in grid view?
Did you open the previous catalog file, or did you import your photos into a new catalog file?
1) There are no question marks, and 2) yes, well, I was prompted to import the photos when I changed the catalog file (which had been changed while it was on repair).
Is there a way to undo most of this, and start everything from the very beginning?
PS: I mentioned the keywords were still appearing in the keyword list. Not only so, every time I click a new picture, the "Suggested keywords" will change according to the one i marked.
If you still have your catalog file (or a backup) from before, you need to use that catalog file. Using your operating system, put it in its own empty folder and double-click on it. Then, you'd have to reconnect the photos/folders using these instructions: Adobe Lightroom - Find moved or missing files and folders
By the way, there's really little benefit to having photos on an SSD. I would move them off of there. The catalog file ought to be on the SSD if you have enough room there.
Thanks a lot for your suggestions, which proved to do the trick. However, now I may need some folder organizer advice, and as I find the Help function and manual a bit confusing at this point, I ask here. If I should start a new thread for this, please let me know.
My catalog is now D:\Pictures\Lightroom Catalog file (the "empty folder" you advised me to create) and the file name is (My name) Lightroom Catalog-2.lr-cat.
My disks and folders are now:
C: Users/(My name)/My pictures/Lightroom.
This folder includes the folders Backups, Download Backups and 4 previews folders: LR4, LR5, (Myname)LR and (Myname)LR-2.
Then follows the catalog files (.lrcat) for those 4.
In the same Lightroom folder are also 9 temporary import data files, each with a db-journal file.
D: My pictures are now stored here.
So are the folder Lightroom Catalog file (as mentioned above) and the files (My name) Lightroom Catalog-2.lrcat, .lrcat.lock and .lrcat-journal.
Something tells me this could have been cleaned up a bit, but I get a bit confused when it comes to what I should keep, and what I could get rid off. I guess this is something I should have done a long time ago, though.
This got a bit longer and more confusing than I was hoping for, so maybe I should apologize right here and now.
Since I can't look inside these folders, it would be really difficult to provide good advice from across the internet.
Basically, if you have a catalog that contains all of your photos, then that's the one you keep (along with the associated previews), and you don't need the rest. Of course, you'd need to keep the photos too. And you need backups of the catalog file and photos as well, on a different physical disk.
Now it sounds like you have multiple catalog files, that one catalog file doesn't contain everything. That only makes the problem harder, you'd have to determine which catalog(s) you really need, so that all of your photos are in a catalog, and then delete the rest. Of course, I always advise people to use one catalog for all of your photos, this makes your life so much simpler in a dozen ways.
Thanks. I'll start by changing the name of a couple of these catalogs (add an extra "x" or something), to see if anything changes. But you also mean I should point the backups to a different disk? That's OK with me, but I thought LR would store them in its own folder by default?
By default, LR puts the catalog backups in a child folder of the catalog folder. The backups really need to be on a different drive than your catalog so that if one drive goes bad, you don't lose everything.
In my opinion, it is mandatory that backups go on a different disk than the originals. If your originals are on D:, then the backups must be on C: or E: (or some other drive that's not D:).
The reason for this is when the drive fails — and it will at some point — if your originals and backups are on the same drive, then you now have zero copies of your photos and catalog file. I'm going to guess that you wouldn't be happy about that. If they are on different drives and one fails, you still have a copy of everything.
Some very good points there. I'll figure out how to redirect the backup files. Thanks a lot for your help (and patience).
