I am not sure wether the RAW file or the embedded JPG is corrupted, I look at what I see.
But to complete my findings so far:
- I ran the most extensive OS X hardware check (more than 30 minutes) and OS X found no hardware errors
- I opened the file with Camera RAW and saw the corruption, indeed other options may look at the JPG (Preview)
- I saw the corruption in the DEVELOPMENT module of LR
- I cleared caches
- I removed the LR catalog
I completely don't understand what's happening as files get corrupted at random. I thought maybe the Camera RAW update 7.3 might cause problems. I am even reinstalling software and trying to retrace when it goes wrong
I haven't checked my Display Profile (I created one use XRite). Memory cards are not the problem as they were OK before I put them on the harddisk, I never import directly from the card. So also no cables involved. Also no network between the harddisk and the computer, all local files.
