I had a HORRIBLE crash with my Mac resulting in the rebuilding of my iMac OS directory with Diskwarrior (thank you man!). Unfortunately, it resulted in the inability to open aperture (due to plug-in failure from what I could gather from the internet/forums). Nonetheless, I reinstalled aperture 3 and was able to recover my aperture library. Now, here is the tough part: When I opened Aperture now, there are many BLANKS where the pictures used to exist before. It appears that the master files are gone. I believe I kept my library as a MANAGED (default) not referenced but I could be wrong. Nonetheless, I can NOT find the pics that are missing in the library. I managed to find SOME of the pics on my hard drive under a "RECOVERED" folder, but not all of my pics are there. I tried REBUILDING the library, but it did not help with those files that were missing master pics. In fact, instead of showing the # of pics that should be in those projects, it now just shows a BIG FAT 0 for what used to be there. I THOUGHT I had a backup using Time Machine, but apparently TIME MACHINE never made any back ups (ie the Library (sans some of the files weighs in at 60gig+, the Time Machine backups are like 5 gig). So, am I totally screwed now? Thanks for your input guys. I put a question up on the Apple Forums, but didn't get much of a response.
