I added four more gb of memory to the device; now it only sees / reads what is on the external memory. I have tried to change the system settings > USB mode from MTP to MSC and back again, but in either mode, the device only sees and plays the songs on the external memory. Windows Explorer has been seeing both the internal and external memories, so I know the songs on the internal memory are still there.
Does anyone have any ideas about how to solve this?
Many thanks in advance,
