For the past two months, I’ve been working on a plug-in to verify image files in Lightroom. The plugin works by computing a hash for each file which can be thought of as a digital fingerprint. As long as the image is unchanged (i.e., the file is still ok) the hash value will also remain the same. If the image file becomes damaged or corrupted, the fingerprint will change and plugin can identify this by comparing the hash to a previously stored value.
The plugin is now available as a beta and you learn more about it here:
