I have the same issues. I have a car camera and keep wondering why one day it says it's recording, the next it's not. I put the 64G Micro SD into my mac and try to erase it. It says it does, and I can try to trash files too, and I empty the trash. Then I unmount it and remount it and the files are still there. So yeah, controller is not working or memory is stuck or whatever. Regardless, I'm sure a lot of people bought these like I did because they were on sale. But they're junk. I'm switching Micro SD companies and never coming back. When you don't test your products, or sell junk that doesn't work, you lose customers for life.
