I'm having an iPhoto issue. I have over 17,000 photos in iPhoto. One particular, recent batch keeps having an error. The thumbnails for the 82 photos are always visible. When I double click on one the photos I get an error that says: "The volume for "xxxxxx.JPG" cannot be found." It's specific to one event or batch of 82 photos. The photos and events prior and after are fine. I've restored the pictures from the SD card and the pictures will work like normal in iPhoto.... for a few hours and then I start getting the same error. Same with Time Machine. I even went back 9 days (which is as far back as I'm willing to go back since I've uploaded pictures that I don't have back-ups for past that). Again, I'll restore iPhoto, the batch of 82 photos will act normally, as in I can see the thumbnail and then double click on it to get the bigger image and then suddenly I'll get the error again. I'm attaching a picture of the error. I'm lost. Any help? Please?
