I have tried different ways to transfer 23GB of music to my 32GB SD and the results are always the same. I've tried dragging my folders containing the music onto the card with the phone in USB transfer mode (both pc and mac), I've tried it with the SD plugged directly into the mac, I've copied all my files into Kies and done it that way. The result is the same: the transfer completes but then between 2 and 4 GB of the data appears on the phone. Then when the card is plugged into the mac again it shows that the files are gone. Is this happening to anybody else or can anybody explain this? My ipod was stolen recently and this phone and card were to be an elegant solution so if anyone can help me it'd be very much appreciated.
