Disc error on MP4 player

December 2016


After disconnecting/reconnecting your MP4 player from the USB port of a PC, the device displays "disc error" or "Device switching failed reconnect device please" when you put it on Music, Amv, Record, Voice, etc.. Windows may recognize but shows that the unit is not formatted.


To remedy this, download the HP USB Disk Storage Format Tool and format your drive to FAT (FAT16).
