  • Need tips for eliminating HDD noise

    I am getting a fair amount of HDD noise through my speakers. I have an Asus Pundit MB using onboard sound (SoundMax). The HDD noise drives me nuts, especially if I'm playing a quiet song. The harder the computer works, the worse the noise gets. The engine speed does not affect the noise, plus I have a nice solid ground point, so I don't really think grounding is the issue here.

    I did read where some people had success eliminating HDD noise by grounding the PC chassis. I tried this, but it did not help. I also tried using a cheap usb sound card instead of the onboard sound. That didn't help either. My next step is to try using an Audigy PCI audio card that I have laying around. Is there anything else I should try?

      No, I did not. Everything I've read says that you should not need one if you do a proper ground. When I have some time, I'll hook up a AC PSU to the carputer and see how it sounds. If the noise is gone, I'll have a good indication that it's a grounding problem.

        Ok, I just tried an Audigy 2 in place of the onboard sound. The HDD is much fainter now, but it's still there.

          The easiest thing to do is buy a Ground Loop isolator, it will remove the device whine 100%. If I were you though, I would get the isolator from Best Buy. http://www.bestbuy.com/site/olspage....=1122655296186, it is the only one I have used that does not muffle sound quality, infact it improves it. I use an isolator on the front, rear and sub. The price ($17.99) is a bit much, but like I said it does not mess up sound quality. Try Ebay'ing it, I got lucky with mine and got 5 of the units for $20.00.

            I broke down and bought one of those isolators (IEC GLI) off of Ebay. It came to $11 including shipping, so not too bad. In the meantime, I'm going to keep fiddling around and see if I can't solve the problem without the GLI.

              You have to check windows sound mixer and make sure all unused audio sources are in mute (mainly mic, aux, line in, etc).

              In 90% of cases mic input picks up noise from HD and other sources, it's very sensitive, this is norlmal. Just mute all unused audio sources.

                Well, the GLI "fixed" the issue- or should I say "hid". I don't notice any difference in sound, but I wish I could have eliminated the noise without the GLI.

                  The only way I think is possible is to put ferrite chokes over each of the cables of the device that is creating or receiving the noise. Its worth a shot.
