Did not find the ones I am after, strange how they have just gone.
Funny things, hard drives! Probably doesn't help you this time, but our routine, after transferring photos from camera flash card to PC, is to always burn a CD of any photos we value. Only then do we delete pics from the flash card.
Likewise, we make a back-up copy of any photo CD that we take to the printers (much cheaper than printing your own). Perhaps a little over cautious, but CDs are dirt cheap, and it saves much anguish, should things go wrong.
