I have another dumb question. For some reason, Apple decided that iPhoto should try to import every file on external media that it thinks is image data when iPhoto is running. Unfortunately, the external device that I have connected is not a plug-in camera, and iPhoto shouldn't be doing anything with it. Because it is trying to suck up the data, it crashes. I've tried to tell it to not run any applications when a camera is connected, and I've looked for and didn't find a Preferences window in Image Capture as suggested elsewhere, but iPhoto keeps trying to access my external drive and obviously can't handle the large amount of data enough to see that it's not a plug-in camera. I also can't disconnect the device because I need it now, and I'd also like to get into my iPhoto library. How do I tell iPhoto to stop probing my USB ports for external devices?
