My K-r Burnt my Sandisk and Went Nuts! :-(

Had a tour to the Hong Kong's highest observation deck, the Sky 100, with my Gold/Brown #107 K-r.I went up there for an hour and took some good shots (I believe ;-)). When I decided to leave and wanted to shoot a few more group photos with my family, my K-r hanged up and my Sandisk Ultra 16GB SD card was burnt!! The problem only happens when I shot some continuous single frames in a chain a while
