So, maybe I'm the only one with issues? My SD card will work fine for days at the moment. However, when I start downloading multiple torrents at a time on my phone, my phone would no longer see my SD card after awhile.
Previous setup: 64GB microSD formatted as FAT32. After awhile, my card would stop working properly and I'd have tons of corrupt files. Even files I had not touched.
Current setup: 64GB microSD formatted as NTFS (mounted using Paragon NTFS & HFS+). Card would still crap out if I downloaded multiple torrents. Seems more stable when I have one active torrent at a time. But now, when my card craps out, my files are still good and my filesystem is intact.
