Hey Guys,

I've used my Lumia 720 for about 9 months and always had the same SD-Card that worked perfectly. A week ago, I took that SD-Card to put it into another device. (Nvidia Shield on Android) Today I went to the store and bought an exact copy of the SD-Card. My phone is recognizing it, but when I put music or videos on it, my phone doesn't recognize the files. When I take a photo and the photo normally has to go onto my SD-Card I either can't find it on my phone.
When I use the app to sync on my phone (error 83000000) or Windows Media PLayer I got the same problem.

Any solutions? I already tried to format the SD-Card and to put the music onto my SD-Card on my computer. I'm 100% sure it's not a SD-Card problem.

I would do a factory reset.

Try formatting the sd card and again copying all the data again to the sd card. Insert it into the phone and it'll work. I bet.

this also happened to me before, same thing on my 720. can u check the sd card itself and check the kind of files
that is stored on it ? does it show under the "Others" tab ? if it does then we have experienced exactly the same prolem.
what i did is i safely remove the sd card but i didnt remove it on my phone then did a soft reset after that i wait for it to load
for like 20 mins then it worked
