Based on the answers provided, Lightroom itself does not appear to offer a built-in content-verification scan that will identify every corrupt RAW file in a catalog.

A practical workaround is to test the files outside Lightroom with a batch conversion tool. One suggested method is to use ImageMagick from the command line to batch-convert all RAW files to a dummy output format. During conversion, it should report any files it cannot read properly, which helps you identify the corrupted images without manually stepping through them in Lightroom.

So the useful approach is:

• batch process the RAW files with an external converter,
• watch for errors or log output,
• use that list to locate and remove, restore, or replace the bad files.

This won’t fix the corruption, but it can save time compared with checking files individually or doing repeated binary-search batches inside Lightroom.
