Absolutely you have a chance to recover data from sandisk, although you formatted it. and if you don’t recopy data on sandisk, you can get the old data back completely. <spam link removed> you can refer to. hope this can help you fix the problem.
Nice try Tommy. But if you read the OP’s post carefully you see that he said, "I shot a 10 minute long footage on my Sandisk SD card.Then it was mistakenly formatted, and then re used (to shoot some videos and pictures) and then again formatted"
So you see there was data stored on the card, it was formatted, more data written to the card, and then formatted again. I doubt even the program you provided the the link to (aka SPAM) would help.
