One of the worst data losses of photos I had was when apple switched from iPhoto (which I'd organized meticulously) to Photos. It wasn't until a few hard drive crashes later did I realize how poorly Photos imported the pictures. I found old iPhoto data files on an old Time Machine backup and was able to restore some, but anything that was linked was long gone. So most of the digital photos from my 20's are gone.
