I just went to take a few pics and somehow my SD card has been wiped 
Luckily I didn't lose too many pictures.
My camera is set to continous for picture numbering but now when i put the card in it's back down to number 0007.
Why has it done this, can I recover my number, so that when I drag off the SD card I dont get numbering clashes?
