I have an Aperture library that I've been using for several years.
In the past week a number of recent photos and movies have mysteriously disappeared.
The missing files were all safely imported within the last week (I had reviewed some of the movies within Aperture, so know this to be true). The files were all referenced on an external drive.
Within Aperture the files now have a "referenced file can't be found" icon.
I've tried searching for the missing files manually, including within the Aperture library package, but they cannot be found anywhere.
How can I (a) work out where the missing files have gone, and (b) identify the cause and ensure it doesn't happen again?
I'm using Aperture 3.3.2.
