The Drive LED will light or flash whenever the USB stick is being accessed.
- If the LED is flashing regularly like a heart beat, this indicates that information is being written to the USB stick.
- If the LED is flashing briefly or randomly, this indicates that data is being read and written to the USB stick.
It is inadvisable to remove the USB stick or power off THEA500 Mini while the Drive LED is showing activity, as this risks creating partially written or corrupt files.
