Random Hard Lessons Learned of the Day on this Christmas Eve:
DO NOT put a microSDXC formatted with exFAT accidentally in another device which does not support exFAT. microSDXC is technically backwards compatible with microSDHC so the non-exFAT supporting device will happily accept the card, not understand the file system, and utterly destroy it. I don't know who designed exFAT but I want to fucking kill them right now, because unlike all other file systems including original FAT, exFAT does NOT store a backup file allocation table. If you fuck your file system up, there's a good chance all your shit is gone. And all you need to do to fuck exFAT up is stick it in a device which doesn't understand it. Fuck you, Microsoft. Even when I use Android you still find a way to fuck up my day. Now I'm running data recovery utilities to see if anything can be recovered from my microSDXC. I hope to God I still can recover some photos I want. The rest of my data might be gone forever.
