A Nef file edited and saved to Jpeg yesterday was ok. Today the Nef file has red lines (diagonal due to a levelling crop). Yesterdays Jpeg and today's attached. Restarting LrC 9.3 did not help.

I'm now convinced it's a Library glitch. Red lines are not there in the Develop module or any other Raw file viewer. 

Here is the same image viewed in the Library and Develop modules.

Then the RAW file itself is not corrupted, but the preview that is shown in the Library Module is corrupted.

 

What happens if you select this photo in the library module and Library->Previews->Build 1:1 Previews?

    Try turning off the option to use the GPU in the LrC Preferences on the Performance tab and test.

      I've not tried that yet. Mainly because it's only affecting one image in a folder that holds 100s Thinks for the hint.

      Normally this is a sign of hardware failure:

      memory card going bad

      problem with the card reader

      USB cable broken

      bad sectors on the hard drive

       

      In this case, since the problem is new and well after being copied to the hard drive, the first suspect is a bad sector on your hard drive. Of course, a good second opinion is to try a Nikon program (View NX-i or Capture NX-d) just to verify it is not a raw interpreter problem.

        Thank you for your response. I've since found that opening the NEF file outside Adobe it is fine. The problem only manifests in LrC and Photoshop.

        That's because other software often shows you the JPG preview which can be uncorrupted when the RAW image itself is corrupted. So, the conclusion remains ... the only known source of this particular type of corruption is hardware.
