Is it possible that my internal hard-drive produces sound that is audible within logic. During fadeouts I can hear a noice similar to the sound that the haddrive produces when it works with audio at very loud volume. Michael in sweden.

Yes, a friend of mine had that problem too. It was due to a ground loop (via Protective Earth) that involved his computer and his mixer. Ingo

Hi Vincent, people, >I had a similar problem and just recently found out what is causing >the problem. This is definitely an earthing problem.

I have had similar noises, even though all my gear runs off one plug-board. Could this be a ground loop? Anyway, I was thinking that connecting the equipment chassis' with a large ground cable might solve the problem. Any comments on the electrical wisdom of this? Cheers, Thomas
