Unable to update MAKE tag using exiftool 12.76

[JeffGoldner]

I have been updating missing or incorrect MAKE and MODEL tags for scanned images. With my latest scans, I can update MODEL but MAKE throws an error.

Details:
I usually scan with Silverfast. Last week, I used their latest version (9.2.3) on MacOS to scan a roll of negatives. I then tried to update the MAKE and MODEL fields using exiftool 12.65. MODEL can be changed, but MAKE throws this error:

exiftool -make="Nikon" -verbose 20240328-20240321-01.tif

I then tried this on scans from last June, when I used Silverfast 9.1.8. No problems encountered, I could change both tags.

Since these files are on a NAS and accessible from my PC as well, I used Explorer on Windows 11 to look at Properties for the files I could not change using exiftool. From there, I could change those fields without issue.

Found the -m option which lets the change take place.

Can you provide a sample file that Phil can look at and decide if he needs to change something on the exiftool side or if a issue needs to be filed with Silverfast.

I don't need a sample for this problem. There are a number of makernote types that ExifTool doesn't understand. This warning is due to a small chance that ExifTool could corrupt unknown maker notes when rewriting, but honestly I don't recall ever seeing any cases where this happens.
