I keep having trouble with disk corruption on my Mac (running Mojave). I have a Lightroom Classic catalog with over 500K images in it. It used to run smoothly but over the past couple months I keep having my system performance slow down while using Lightroom until it's at a crawl, not only with Lightroom but is slow with other apps as well (Chrome, mail, etc.).
When I run Disk Utility, it tells me the startup disk has corruption bad enough that I have to run it in recovery mode in order to repair it. I've tried everything - I erased and reinstalled the operating system from scratch and clean installed Lightroom and every time it is apparent that the Lightroom catalog is the culprit.
The catalog does open and I've optimized it many times. I see a temporary improvement after optimizing and running disk utility, but eventually it always happens again.
Anyone have any suggestions how to repair the catalog so it doesn't keep happening?
I have my entire 15+ year archive in the catalog so starting a new catalog from scratch isn't really much of an option.

You have a COMPUTER Problem. Hard drive is failing.
It is NOT the LR Classic catalog that is corrupting your drive. It is the drive itself. It is failing.
The LR catalog is just a Database file. The only program that reads from it or writes to it is LR Classic.
The catalog file is no different than any other computer file on your drive. It is just a bunch of "Ones" and "Zero".

So normally I wouldn't repeat what someone else has said, but in this case it is worth repeating.
Your hard drive is failing. This has nothing to do with Lightroom.
If you don't have backups of everything on a different disk (why not?) then you need to make backups of your catalog file and photos on a different disk, immediately. That's IMMEDIATELY, meaning stop what you are doing and make these backups right now, no excuses. And once you have the backups on a different disk, test them to see if they work properly.

Hi - Thanks for the imput but here's an update and it's defintely NOT a hard drive problem. This was happening on different machines when using the same catalog.
The corruption was in the catalog, and it ended up cascading to some file corruption within the system when LR would attempt to read it. I created a new, empty catalog and imported the pix from the old catalog (this took a couple days). I've been using the new catalog for several weeks now with zero issues and the problem seems solved... no issues, everything running smoothly again.
