[Q] micro sd file viewing problems

[Valhalla87]

Ok
Have a Galaxy note 10.1 2014
No mods not rooted

I have a 64GB micro sd XC SanDisk ultra card.
It sees it and i can put files on it and read those files, but eventually i cant write to it anymore and then it says the sd card is empty but i see it still has the same amount of space used but cant see any files, didnt see any sd removed statements or anything. Still can see the files on my computer with a direct connection to the sd card but not through the tablet.

Thoughts?

I also sometimes get an "unfortunately, gallery has stopped" pop up box

I had the exact same problem, even if I formatted it lol. Had to be returned as defective. There is a tool on the sandisk website that will format the card in a specific way. Would not do mine though as goosed. Good way though to tell if your card is knackered.
