On vacation I had this card and three 16GB cards from other manufacturers there. The camera was a SONY DSC-RX100. All the photos I had stored on this Samsung Card was lost, because it was suddenly realized over media of any equipment. Not even a data recovery company could help. The 107.10 EUR for the analysis were for naught, a successful rescue would have cost an additional 300 EUR plus disk. The map I had like three other treats. Since only one has failed, the cause of failure is likely not related to the treatment. tl; dr: Stay away!
