A user called and told me that his entire photo archive is missing. He reported a set of actions done by himself, but they are related to email, and I doubt they really have any connection to photos.
The computer used iMac current version 27", with 1Gb of HDD.
I am a Win admin, so this is a new field for me.
I would need some help to see where I could take look unto restoring the database of iPhoto which held all the data.
