I have used the Samsung EVO SD cards all along. I had one card awhile back that started unmouting itself after using Spotify. I figured it was just a bad card so I ordered a new 64gb Samsung EVO min sd card. Again, same thing happened. The card had only been used for about 5 days and has never been in anything but my phone. I was using spotify and the card becomes corrupted.

I have tried running checkdsk and formatting. Windows cannot format it and checkdsk points to the spotify folder. After some investigating I found the folder that caused all this. It is at spotifycache>Storage>5b. Folder 5b is corrupted and is causing all the issues. Windows wont let me delete it. Does anyone have any suggestions?
