I am having issues with external SD cards. I have 16 and 32 gb cards and every 2-5 days they become corrupted/damaged/blank. I have to format them and copy my backup files over at least once per week. I have had no luck finding a good solution for the SD card problems. I notice that my SD card will randomly mount / media scan / antivirus SD card scan when I unlock my screen. I assume this is causing the problems. I want to leave my external SD card UNmounted until i want to use it, then i will manually mount it under settings. My problem is when i leave it unmounted, Android will automatically mount it later when my screen is off. How do i change this so that the external SD will ONLY mount when i manually mount it in settings?
