I was adding a photo to iphoto library when message said disk full some of your pictures may be erased. 2 seconds later iphoto library had 0 pictures. tried to fix but am told library is OK
First of all, you need to make some space on your hard drive by deleting some things, or moving large files to an external, etc. Once you have space available, try a rebuild of your library like this: http://support.apple.com/kb/HT2042?viewlocale=en_US
