When I push the write protect switch on the UltraBay 1, the write protect light does not change.

This is because the UltraBay needs to be power cycled. The correct procedure for toggling the write protect on the UltraBay is as follows:

1. Turn your UltraBay off.

2. Toggle the write protect switch.

3. Turn your UltraBay back on.

This process should change the write protection state.
