Okay, you may remember I had this problem before. I click on a photo in iPhoto and it tells me the volume for the photo cannot be accessed. Well, I have since then reinstalled the OS, reformatted the external hard drive to the Mac OS Extended format and then recopied over all the photos. Used iPhoto Buddy to create libraries for each year so that there aren't 11,000 photos in one library. In fact, this one might have 1000 at most. Tonight, same thing happened, tried to just look at a couple of photos and gave me that message and locked up. Force Quit isn't in the menu and no matter how many times I click Quit, nothing happens. So, what's up with this?
