Is the SD card safe in the airport x-ray machine. The other time, I placed my SIM card in my wallet and went thru x-ray belt. (went to china) All the phone numbers got deleted, the card in the handphone was fine. I wonder if its the same for SD card. Anybody brought spare SD card in the bag and pass thru x-ray before? Or is it just those made in China X-ray machines...:think:
