I've have never met anyone who can do this. However, I would like to say that no one ever forgets anything. Recall is the problem. Why do I say no one ever forgets? Hynpnosis. A really proficient hypnotist can, I'm led to believe,can take his or her hypnotized subject right back to a specific day and a specific event. They can ever recall minor detail not consciously observed.
As a practioner of Vipassana Meditation, I've have found on many instances, things arising into my consciousness of events - often very insignificant and innocuous events - which have happened to me at various stages in my life, so it is all locked in there somewhere.
As every experience and every thought also has an emotional aspect to it, the emotions are also recorded and left within us, to later spring up as sensations...but I'm getting into another area here.
Sorry I can't help you further.
