Hello,

By chance I found the ExifTool after having problems described on the site https://exiftool.org/fix_corrupted_nef.html and think this might help me as well.

After I changed from the Nikon D90 to a D7500 I also made the mistake to transfer with the old Transfer software and thus corrupted the NEF files. They're readible but the resolution is worse and several functions in Capture NX-D are disabled. A Nikon help guy was very friendly and came back to me after a few days but couldn't help.

I have tried the software as described in the link above but get an error message that my camera isn't supported. Is it possible to modify it to include the D7500?

Thanks in advance,
Maurice

It will be up to Phil to see if it can be done, but you can get prepared by making some images ready for him.  In this previous post, he needed a correct image and a corrupt image for each of the various compressions and bit depths. 
"It didn't work" isn't helpful. What was the exact command used and the output.
Read FAQ #3 and use that cmd
Please use the Code button for exiftool output

Please include your OS/Exiftool version/filetype

Send me one of the problem images and I'll take a look.  My email is philharvey66 at gmail.com

Thanks Phil, I just sent you 4 pics (2 different, each from old and new transfer versions). Hope they'll arrive well since I had to use my business email due to their size.

Hi Maurice,

I got the samples and have updated fix_corrupted_nef to support the 7500.  You should be able to fix your NEF's with this version (3.2).

Hi Phil,

I saw that the page is updated but I believe the zip still contains the version 3.1 (I still get the same error when using the PC version.)

Hi Maurice,

What version number does it show when you run it?  If it doesn't show 3.2, then you didn't download it properly (try clearing your browser cache and downloading again).

Hi Phil,

just tried it again and the new version 3.2 is there,.... AND WORKS PERFECTLY!

My test file was fixed and can be read and modified by Capture NX-D. Your tool has saved around 800 pics from my California vacation!

THANKS!

Maurice   :)

(I'll follow your donate link...)
