Not entirely sure Lion is to blame but in iPhoto we have lost all events information after a manual back up. We back up all photos onto an external hard drive. Usually we do our backing up using time capsule which works well, but we wanted to do an external drive back up as well to keep at a different site (in case of a fire or a break-in). But in doing so (and this was done by the old fashioned way of dragging and dropping picture files onto the external hard drive) we have lost ALL Events information from our photos. None of the pictures have gone as such but all our photos now appear as one event with 4,000+ pictures which is clearly a mess to try and replicate. Has anyone else had any experience of this and what should I do? Should I do a restore from Time Capsule or is there a more neat way of restoring my previous information? We use the latest iPhoto (iLife '11) and Lion (10.7.1). Can anyone help.
