I moved four of my games onto a SD card, and some how during the process it deleated all of the memory.
has this happened to anybody else?
is there any way i can retrieve it?
It hasn't happened to me, but i'm not sure it will be retrievable.
Though there is a small chance that there might be a hidden garbage folder in your card. If I remember correctly, aren't you able to download those games from the store again?
