Hello I have problem with SDCX card 64 GB. After 6 months of irregular using, SD card in computer "freezes". The card is not removed from the computer. There is no error in Device manager, tryed to reinstall drivers. Using the latest Windows 1909. I thought it is problem of card, I have bought new 64GB SD card and have the same problem. Both cards are ok in other computers. I have checked with 32 GB card and works ok, but 32GB card is not enough for user and 64GB was working ok before. For example I create directory and must wait 1-3 minute when it creates. Or when I click the card in "My Computer", it takes some minutes when it opens. Also the copying give some errors it can not copy or write. Can you help me is this the hardware issue or software ? I have the video but cannot be attached. I guess I'll complain in our local merchant.
