Last week you walked me through relocation of my masters in aperture 3. Finally it came down to the fact that they were gone for good. The last time I emailed you I said I was on my way to my local Apple store. They suggested the data recovery application, Data Rescue 3. It worked well. I retrieved a lot of my most recent trashed photos from my hard drive and from several sd cards. I appreciate all of your help. I learned a lot!!
