I bought an SD card by the seller WE_Sell_Things who apparently no longer sold on Amazon. I can only warn against counterfeiting in general, which has a much smaller memory than specified. (Eg 4 instead of 32GB in my case) By manipulating the register any memory size can be specified, Windows or any other OS does not detect the error. Only when the actual memory of 4 GB is full, you will notice the Bes *****, all other data will be written supposedly on the map but in fact only older data are overwritten or there were only the folder so creates the directories , Up to 4 GB or more has moved to the SD card, the deadline for the right of withdrawal is often already expired. The best immediate test with h2testw or similar program !! This is a free tool that tests the complete memory. With me was the test that are ok only 3.2 of 32GB .. (image)
