    Does everything as expected. The connection plug is the same as on samsung phones (so it works with mobile as well as PC with USB adapter) BUT if the unit gets moved, it sometimes goes 'offline' because the cord doesn't stay securely seated in the HD. Must be careful that unit will not be accidentally touched when data is in transfer.
