That's unfortuate....also why many of us keep stressing to folks to backup all their files on an off-computer USB-Flashdrive.
Still, your situation seems to be quite rare....even for MAC folks. I seem to recall only a very few instances of MAC folks having old files disappear. IF it was endemic, this forum would be screaming with hundreds posts complaining.
I saw one post where they found them in their recycle bin...which didn't show up in their normal search.
