Photoshop and Lightroom: Won't open D300 NEF files
This really annoys me! Photoshop (v21) and Lightroom won't open the Raw files from my old D300. I get a message that Photoshop doesn't recognize the file format. WTF?! (excuse my language) I can see a preview in Finder.
This problem seems to be known. Is there a fix? Will there be a fix any time soon?

ME TOO! I have five thousand NEF files mostly created with D-810 and some with D-300S Nikons that will not open. I have been in a dialogue with two different companies that purport to have software to fix this, but so far no luck. I also researched with Adobe and Nikon, downloaded the Nikon Codec latest version. I get the same error message on any NEF files now, using CC 2020 21.1.1. I get in Bridge, just the NEF logo and the file names but do not get a thumbnail, and Photoshop returns an error that the file is not a valid Photoshop file.

The D300 has been supported in Photoshop for many years.
How are you getting your photos from camera to computer? Older Nikon software is known to render images unreadable to Adobe software. Have you tried eliminating Nikon software from your workflow when importing your images to your computer?

No issues here with opening D300 Raw files in v21 so, as Todd says, best if you upload one of your problem files for us to investigate further.

@Todd_Shaner: An update on my particular situation...
I used the tool for which you gave us the link, fix_corrupted_NEF.exe but got errors and no repaired files.
