I just got a Samsung Exhibit II 4G with Android OS. I cannot transfer files such as ringtones and music to the sd card in the phone while connected to my pc (Vista 32-bit) via usb. I finally found drivers and got them installed. Then ran Zerg rush root so that the pc would recognize them. USB debugging is on. I come up with 2 new drives - finally! - but when I double click it says "Please insert a disk in drive 'x'" What am I doing wrong? Please help!
