So I bought a Galaxy S5, and with the 128GB microSD card capacity it boasts I decided to get a 64GB card to put my music (and maybe some other media) on it. It was a generic card, but it had great reviews so I jumped on it. I start it off as usual, shutting down my phone, popping in the card, booting back up and formatting the new card. Off to the races, right? Not quite. I connect it to my computer, create a music folder on it and begin transferring my music. Well the transfers kept stopping halfway and timing out, I assumed it was because I was trying to transfer too much in one go so I did transfers little by little. I go on and search for the files, not only are very few of the folders there but most of the files are gone too. Same for any other media I tried. I tried one other thing by transferring files to internal phone memory then to the card via the phone file browser, and seeing if my less-important apps would move to card. Those files pulled a Houdini too, and the apps I moved became corrupt and wouldn't respond. I thought it was the card, and I've had junk SD cards before, so I went and bought a Samsung Essentials Class 10 64GB card. I went through the whole process again, but again I had the same problems. Does the Android system have problems formatting such high capacity cards? I know higher capacity cards need to be formatted a little differently, but with Samsung boasting 128GB capacity for this one surely it should be able to deal with a 64GB right?
