New user of an S4. Got a 64GB Samsung EVO SD card to hold my music. Put SD card into card reader and used Win 7 to copy ~2K tunes to the sd card. Almost a third of them arrived corrupted, though fine on PC. Samsung says I can only transfer 10 files at once or problems happen. Gonna take forever. Is there a smart way to do this automatically? Thanks for advice. I've also tried using my PC's music player (Foobar) to transfer, used Win Merge, etc. Hundreds and hundreds arrive corrupted and I have to start over.
