There will be no blue light while the Tivo is transferring to the PC. When you are transferring from PC to Tivo, then there is a blue light. With Tivo to Tivo, only the receiving unit will have a blue light.
You would need to check the ToDo list to see if there are any pending transfers, if any, highlight and press clear. Then you can reboot the Tivo to clear the error or ghost transfers.
