Because of the many good reviews I have send me a replacement card. This made for 1.2 to 1.3 GByte (59 GB) limp. H2testw showed an error message. Anschließlich could neither Windows 8.1 nor Windows 7 start something with the card. The Windows error correction failed, chkdsk could no longer align. The hammer was that I could not even format the media, just as I was able to delete the two test files.
Have the map then replaced by a 64 GB Samsung that does its job perfectly well!
1 point for:
--- Reliability
--- Many problems during operation
