I have an SE/30 which I just cleaned / recapped recently. It used to make no sound at all, but after a thorough cleaning and recap, it now makes this abrasive startup chime. Also, it was/is unable to read anything from an HD I have hooked up to it, which I have confirmed working on another machine.
Any help is greatly appreciated. Video of the sound below
