Despite what WDStaff say, you can turn the buzzer and the two wake/start beeps off. (Shuttle 4 and 8 bay).
This used to drive me nuts years ago and I managed to silence the buzzer back then - I’ve just added a 2nd Shuttle to my collection so had to remind myself how to do it… so here you are…
Start the G-Speed Software Utility and let it connect to your Shuttle.
Then click on the Dashboard Icon. On the Left hand side of the Utility window, you’ll see a list of the System Status showing the various components of the shuttle - one of those is the Controller. If you click on the word “Controller”, it will take you to a window showing you a Component List - scroll down that list and you’ll find the Buzzer listed. You can then click on the “Settings” button on the right side of the window and choose to enable or disable the buzzer. Hey presto, nice peaceful undisturbed night’s sleep without your Shuttle waking you up
