Do any of your recent backups exhibit this corruption?
By the way, you don't really say why you think the catalog is corrupt ... do you get an error message indicating it is corrupt? Exactly (word-for-word) what does the error message say?
If it says "in use by another computer program", the solution is to find a .lock file in the same folder as the catalog file and delete the .lock file.
None of my recent backups exhibit this corruption that I can tell. I also am still pretty new to Lightroom and this is my first problem I have had with it. So what I mean to say is how do I find this corruption in older backups? (This is going to make me sound dumb which that has probably been shown already)
The error message I receive is Error Message box title: Temporarily Unable to Repair Corrupt Catalog. In that message the body says: Lightroom encountered problems reading or writing from disk when attempting to repair "Lightroom 4 Catalog" The repair option may succeed in future attempts. If you wish to try again, please check available disk space and close all other applications. This gives me 4 options to click 1. Choose a different catalog 2. Show In Finder 3. Quit 4. Try Again
I have clicked the Try Again option many times and then the status bar pops up and goes about 1/15 the way through and gives me that error message again.
Well, if you can open a recent backup of your catalog file, and you don't get that message, then I would say the backup is not corrupted, and is what you should use.
Well I opened up my latest backup and everything worked. I was uncertain if I would lose a lot of editing and collections and that is why I didn't open up backups, but apparently everything is good.
I appreciate your help and your willingness to help idiots like me!
Not a problem
By the way, that's what backups are for ... you shouldn't lose anything, except whatever you did between the time of the backup and the time the primary catalog became corrupted
