Can't delete any files


I have a problem. I can’t delete any of my files from my external storage (SanDisk SD-card). I tried to delete files by using my xiaomi manager; Total Commander; I even tried to delete them through my tablet and laptop — to no avail. I tried to format my SD-card on laptop, but system said that the operation cannot be done. When deleting files on my smartphone, it says nothing. All I can see is progress bar (from 0% to 100%) and files won’t disappear after that. By the way, when deleting files manually by using laptop (shift+del), files disappear from my SD-card, yet they appear again after a while.

Please, help me to resolve this issue.


it sounds like the card has locked itself into write protect mode. the card will need to be replaced. contact sandisk support to check warranty status. 

Right click the disk where SD card is and choose “Property” -“Tool” to check it.
