“How can I tell how much hard drive space I have left on my VS-1824?”
The procedure works for the VS-1824, VS-1880 and the VS-1680.
From your PLAY screen, hold SHIFT and keep pressing the PLAY/DISPLAY button (this process will take you through 4 different screens with different types of information). The screen with the song title listed in large text displays the REMAIN time on the left side of the screen. This is only for the current partition that is selected, and not the entire hard drive. Simply follow the same steps with songs on any additional partitions to find out how much space is left on those remaining partitions.
