This conversation has been merged. Please reference the main conversation: Lightroom: Photo integrity check
As it stands, *if* Lightroom has to render a photo from raw data, it will pin a corruption badge to it, but some (most/all) of us would probably prefer to know about this immediately, before happening upon the image down the road... I would think that comprehensive detection (e.g. when backing up catalog) would be a good idea, as well as putting corrupt files detected in a collection and notifying user of the problem when encountered during normal use.
