This is the normal behaviour. The drag-drop programmer onboard the LPC824 only pretends to be a USB disk. It will actually immediately flash the target with your bin code and it can not really store the file on the USB disk. The code should start after flashing has completed or after pressing reset.

See https://os.mbed.com/platforms/LPCXpresso824-MAX/ for instructions on how to update the programmer firmware. Note that the Serial port to the host PC does not work by default. You first need to modify a solderbridge.
