The computer does not recognize a microSD card inserted in your Walkman.
Change the setting to [SD Card] as the memory to use.
Make sure that no data is being transferred by checking your Walkman screen. Disconnect the USB cable from your
computer, and then connect it again.
Back up all of the data on the microSD card (not supplied) to your computer, and then initialize (format) the microSD
card with your Walkman.
