I was taking a tour in Hangzhou China and while I was shooting with my Canon 6D, the card out of sudden crashed. My camera won't recognize the card and it showed "card reading error". I had more than 2000 photos in it including the trip in Beijing and Xi'an. I was not able to cover those photos even with the common flash memory recovery softwares. I may have to send it to Sandisk subdivision LC Technologies to recover those photos, for the 64 gb they are asking for $325, regardless how much photos they can recover.Lesson learned: for important shoots, use 32 SDHC card, they are so far the most stable SD cards out there. I spent over $10K for this vacation and most of these valuable memories are gone. Thanks a lot Sandisk! I wish I could give negative stars if Amazon allowed me to.
