Hard drive noise through speakers???

**Pepe** · 04-21-2006, 02:34 PM

Anyone ever experience this? When the hard drive is active and working, I can actually hear it clicking through the speakers in my truck. The audio from the computer goes through my deck, which goes to the speakers. I' only really hear it when the volume is low on the deck, but it is audible.

My first guess would be a ground loop or something like, that but I'm really not sure. It's strange.

Any suggestions?

This noise is tipically produced by noise going into not conected inputs.

So, there is an easy solution, put in mute all not used sound card sources:

AUX, LINE IN, MIC ...

Ground the hard drive to the chasis.

If he is having the same issue as me then that doesn't do much good to solve it. You can actually hear drives and all kinds of little electical "clicks". It's hardly audiable, but there, and mine can even be heard with the amplifiers off. It's not your typical ground-loop noise either.

If your case is metal, then wouldn't it be already?

The PSU is grounded (which connects to the mobo) to the chassis, The case for the PSU is metal, that mounts to the metal computer case, that holds the metal HDD which is mounted on metal rails with metal screws. Make sense?

What you really should do is try adding a good ground from your PC case to your chassis.

Can you please explain, so we can better assist in trouble shooting this, how you have the computer installed? Likehow and where are you drawing power from? What and how the audio from you computer is feeding your head unit and so on...It will definately help me to assist you in trouble shooting this as I think I might be able to get rid of your noise problem bu what I read here.

Thanks
