Sony wrote about it: The memory card is formatted incorrectly. Formatting will delete all data on the memory card. Data cannot be recovered.
It's a game over process once this is happened to you. But if you wanna give a try for this situation and this is a long process with less hope. The Data Recovery Center may going to do a wiring process to decrypted the datas. But this is no guarantee for success rate and for sure it will be costly to do this work.
So a reminder to all user of a Sony Camera to be careful of pressing anything and read clearly before you may click. Because one click away the datas may gone forever.
