usb not writable or readable Since I have upgraded my mobile to marshmallow I am not able to see the files in  my san disk 128 gb pendrive on either MX player or file manager which I have downloaded from play store. I was able to do so earlier. However when I connect my pendrive a notification pops up in my notification bar saying sandisk usb drive. But the problem is I cannot see these files in MX player or file manager. Niether can I delete any files from san disk usb drive. Files are only readable there and I can only copy them. They can't be deleted from there. Also when I go in the menu options of the drive my options for moving pictures and video are frozen. I don't know how to access them. They are not clickable. Please help me to allow my pendrive to be readable and writable in mx player and file manager
If your device is rooted Stickmount should fix the problem
