Ouch! I feel your pain but that is nothing compared to what I experienced. I was playing a Playstation Magazine demo CD and it apparently has code in it that erased BOTH my memory cards. Hours of Gran Turismo, Final Fantasy, Devil May Cry and a whole slew of other games that took over 1000+ hours of my life. Those games weren't pick up and play!
My advice is to suck it up and get over it. Hopefully your experience helps others, which is good.
This may be off topic, but in Metroid Prime 2, if you activate some of the echo sensors in a room and leave, your game would be stuck. The sensors will never re activate.
