i have 64gb sandisk ultra micro sd xc1… using it for 3 years with my Note4.
For a few days i can see the all files in it ,but i can not delete any file or format the card.
windows says formatting can not be finished.
i tried so many ways for formatting .special programs , by cmd command made diskpart and clean also…

Also i tried to format with my phone…
The system of the card is exfat .
