I shoot RAW large file. On every CF card, I get about 3 corrupt files out of 200 that show up in Lightroom Classic. Never the same image number. I have tried everything. New cards, new card readers, copying files directly from my Canon 5D III to the computer. Yesterday, I sent Canon the 3 RAW files that show corrupt in Lightroom from my shoot, and they are fine. They also show up fine in Canon Digital Photo Professional. What to do? I have sent my camera in to Canon...always thinking it was the camera, and they say the camera is fine. Now I believe them!
I uninstalled Lightroom Classic and reinstalled it. Yes...it is the latest version, and it has been updated continually.
The problem has escalated. Not only have I been overshooting to compensated for a possible corrupt file on the perfect image, now when I process out to Jpegs, several are not loading into ProSelect. (If I take the HOUR to process out of Canon Digital Photo Pro....they ALL load into ProSelect.)
Are you on a mac or windows device?
New macbook pros require adapters to connect older camera card readers. Sometimes that will show a number of or all of the images as corrupt when they are not. In this instance the images need to be copied from the CF card to an external hard drive or NAS and then imported into Lr.
PC. windows 7. I copy them to a hard drive and then bring them up in Lightroom.
