Hi,
I realized all my RAW files have wrong filecreation and filemodification date/time so I did this to 6536 files. It seems Exiftool change successfully all files but I would like to double check this message.
exiftool "-filecreatedate<datetimeoriginal" "-filemodifydate<datetimeoriginal" -overwrite_original -r
after this I was getting for every single file this message.
Warning: [minor] Error reading value for ImageProcessingIFD entry 146 - /Volumes/RAID RE4 4TB/Lightroom cameras database/Final E-P1/P1019924.ORF
Warning: [minor] Error reading value for ImageProcessingIFD entry 146 - /Volumes/RAID RE4 4TB/Lightroom cameras database/Final E-P1/P1019925.ORF

...
at the end I go this:
1 directories scanned
6536 image files updated
6 files weren't updated due to errors
I have been checking randomly and the files seem to be ok but what is this ImageProcessingIFD coming from?
Thanks in advance.

Hi David,
The ImageProcessingIFD is proprietary Olympus metadata. Have the ORF files been modified in any way? What is the camera model?

Hi Phil,
The camera Model is Olympus E-P1 PEN, the first DIGITAL PEN model that came out to market.
I think everything worked fine. I don't see any problems. These 6 errors Exiftool reported at the end were locked files.
Now at least I have all dates the same and I can start correcting date and time. OMG so many dates everywhere drive you crazy!
Thanks a lot for all your help.
David
Right. It seems that the E-PI writes an invalid offset for that ImageProcessingIFD entry. The offset written is 0xfffff440, which is obviously wrong (perhaps it should be 0x000fff40, but this is only a guess).
But you don't need to worry about this problem because exiftool isn't actually rewriting the file (since you are just changing the filesystem date/times).
