I have some old images I was perusing just now. Oddly I saw one corrupted- and opening it full size in DXO-3 showed several massive issues. Then I took a look at another folder, and saw the same thing on another image.
Another viewer does not show this issue, but Phase One’s Capture One Pro showed the image correctly for about a second and then it went black. Downloading a new copy from the ‘cloud’ showed the same issue (in another file location).
SO while it’s not impossible my images have been corrupted locally and then backed up corrupted it is on a RAID-5 partition with active scrubbing. Doesn’t mean it’s impossible though.
Suggestions how to investigate further ?
