I just put unmounted my sd card from my galaxy s2 and put it into my computer to transfer my music. I have 100+ songs and not even 50 of them are showing up on my sd card and I checked every folder that it might be in and same goes for my photos not all are showing and I really need to transfer all of this to my computer. Currently my phone has been acting up like it wont turn on and the only way I can do that is by taking the battery out and putting it back in and it turns off by itself. Do you thinks this could be the possible cause of this? if not please help me out here!! Thanks.
