Question

How to check all the photos to avoid file errors before backup?

Hi all. Recently I upgraded my SATA 2TB Hard Disk to a NMVe 2TB to use on Lightroom Classic. I always have a mirrored backup of all my photos, synced with the drive origin. Some days ago I tried to open one file and I got a exclamation icon saying that the file is corrupt. Unfortunately I don't have the original files on the Hard Disk before copied to the NMVe. I only have the backup from the NMVe, so my backup has the file corrupted too. Maybe the problem is the NMVe hardware, but my question is simple:

 

There is a way to select all files from a folder and check if it is corrupted or not? Inside the Lightroom Classic? Generating previews? Or a simple way is available? Just wanna check to see what is corrupted from my catalog.  Thanks!

Thanks for all. I think the best way will be generating previews. Not smart, but is what we have. Thanks!

Or you could just look at everything in a file viewer like Bridge. That might be easiest.

If you recreate the 1:1 previews it would have to read the RAW data.  If LrC can not create the preview than the file is corrupt.

It's not much help to you, but LrC can do an integrity check on DNG files (Library > Validate DNG Files). Unfortuentely, this isn't possible with proprietary raw files.

I am not aware of any way to check for corrupted files in Lightroom Classic, other than manually scrolling through your photos and looking for this icon.
