BTW, I did have copies in a friend's computer...but it crashed and he reformatted it...call it suay.
The sim lim guys said I'll lose the part which is overwritten but technically I can retrieve the other pics.. but somehow it doesn't work.. does it mean there are really no ways to get them back? I've tried the software mentioned, but they couldn't scan beyond the 20+ pics.
Try Photorescue, it isn't a free software but a friend of mine has it and he helped me recover some images from a card I accidentally formated. It recovered files up to 4 generations. Hope this helps out.
