Today my 12" Powerbook would not wake from sleep when I hit the spacebar, so I restarted it with the power button. When I opened iPhoto, I was greeted with this message: "An error occurred while trying to save your photo library. Some recent changes may be lost. Make sure your hard disk has enough space and that iPhoto is able to access the iPhoto Library folder." When I clicked on any individual photo, an image of an exclamation point showed up instead. Not a single one of my pictures open up. Then, when I opened up the iPhoto library folder, almost all of the folders from 2007 were empty. My camera is set correctly and they would have been in those folders. I am in New Zealand studying abroad and I've taken over 1,300 pictures. The last time I backed up these photos was a month ago, so I'm missing several hundred pictures. I would be absolutely devastated if I lost them. Is there any way to fix this? I can usually fix these problems, but I am completely lost with this. I have no idea what to do and am paralyzed at the thought of losing those pictures. Any help will be GREATLY appreciated.
