.... I tried opening in bridge but just the same message. The screen shot shows what is on my screen, the edge of one of the ok files is on the bottom RHS.
Thank you
I'm pretty sure it's nothing to do with ViewNX2.
and pretty sure again it's due to corrupted images .. probably what Bjørn described with the disk errors.
I've got a few corrupted raw files, did all manner of disk checks, and whatnot .. no luck.
I'm sure my issue was a result of a failed file update/transfer in maintaining copies of files.
Nothing to do with Nikon's Transfer!
My corrupted images happened years after they had been confirmed to be OK.
Have you done file backups of those corrupted images at any time in the past?
If so, are you trying to view the backed up versions, or the originals?
Have you had any file operations whatsoever to do with those files?
In my old backup routine, I used to have two external drives for backing up too, as well as a local HDD on the PC.
The two external were USB connected. Had trouble with the USB connection, and a transfer stalled and failed. NEFs were checked against the source and destination and apparently were fine.
Little did I know tho that the destination file must have been corrupted .. just could see that easily using raw file viewing software.
At the time I used to use either Windows copy/paste or move feature, and or RichCopy to move loads of files. I think I was doing a wholesale move of an entire archive where the corruption must have happened.
I store all files in complicated folder structures as it's easy to maintain this way.
Only problem is you can't easily see all files due to the complex folder structures.
But I found the only program that is usable in any way to show all files in all folders at the same time is XnViewMP.
It allows you to view all those thumbnails in one borwser window even if you have your images in multiple directories .. saves having to browse through thousands of directories trying to spot more corrupted raw files.
If you try XNView in this mode, note that it does take an excessively long time to generate all the required thumbnails and scan through all the folders. Program will not respond until it's done it's searching.
Once it's done, and it displays all the files in the main directory you've pointed it too .. it will show thumbnails as images. if a thumbnail does show as an image, then it's also most likely corrupted as well.
I use the Page Down key to scroll quickly through the vast numbers of thumbnails in a reasonable time, and scanning each page for non image thumbnails.
Note that you'd probably have to set file/image filters too so that system or settings files don't impede this quick scanning method.
Note that I have about 20 corrupted NEF files, so far unable to fix them with any of the tools I've found to try too.
One of the corrupted images was tracked back and the uncorrupted original was found. File size was exactly the same in both files too .. so looking at file sizes alone may not indicate if a file has been corrupted or not.
I have discovered some corrupted raw files without the help of this XnViewMP software, but I found many more 'hidden' in my archives from many years back, images I haven't 'touched' for a very long time!
