I just bought an external hard drive. The 'My Book for Mac'. Well, I plugged it it...and ran the 'install' or whatever. And now, all 10,000+ photos that I had in iPhoto are GONE. First it said "iPhoto Library cannot be detected". Can someone please help me here?? I'm hoping these photos arent gone forever. I'm having a hard time even knowing how to pull them up "retrieve" them from the external. Also...with an external...I thought I could just drag and drop, or just import what photos I wanted onto the external. But it seems like this thing backed up my ENTIRE computer.
