Today I spoke with a customer who had lost her entire iPhoto library. She had consulted with AppleCare and they suggested that she use Data Rescue 3 to get her images back. She purchased a copy and then ran a Deep Scan on the internal drive of the Mac. She then previewed some images under the reconstructed files folder and was able to see some of her lost pictures so she went on to recovered the images folder.
She contacted us and wanted some help with importing the pictures back onto her Mac. I walked her through importing the Library to iPhoto which can make smart folders and categorizes the picture for easy sorting. She was able to copy all pictures back into iPhoto. I also walked her through importing her music library back into iTunes. She was happy with the results. She then decided to setup a backup with Time Machine and also Data Backup 3 for Mac.
