Re: Checksums, Lightroom, DNGs, and Do We Need Them?

It’s not a question of whether it exists on Lightroom; according to a couple of articles you run it at Library>Validate DNG Files.

As for the purpose Peter Krough, a DAM expert says in the linked blogpost

one of the most vexing problems in asset management is knowing whether the files you stored are still sitting on the drive in an uncorrupted state. It’s possible that they can appear to be fine even though they are suffering from bit rot, or they were damaged in transfer, or have been corrupted by virus or other volume error.”

Krough convinced Thomas Knoll to add it to LR5.

So i think my question is given that it’s cheap nowadays to back up files in multiple locations, how much extra safety do we get from using a system that uses checksums.

Checksums are good, if they are used. But i don't think they are used, so they may be pretty irrelevant.

Right. The first question is what we are going to achieve, what's the goal.
