I recently reinstalled leopard, then updated to snow leopard on my macbook. I saved my iphoto library on an external hard drive and am now experiencing problems putting my pictures back into iphoto. First, I just dragged the iphoto library icon from my ext hard drive to iphoto. The photos were downloaded but there were a lot of double copies, pictures upside down, and events split incorrectly. So I googled and did some searching and found following discussion on apple.com. Someone had answered to copy/paste iphoto icon onto the desktop, and then drag and drop the folders into iphoto (with the autosplit events disabled). THis would preserve my current events organization, etc. When I attempted to copy iphoto library onto my desktop, I received the following error message: The Finder cant complete the operation because some data in iPhoto Library cant be read or written. (Error code -36) Then, I tried to just open whatever was in that folder that appeared on my desktop and received another error message on iphoto. Please give me any advice you have. I am just nervous about losing all of my photos. THanks you in advance.
