Re: feedback from internal hard drives
is this ground loop isolator similar to a power conditioner? and what do you mean by cheater plug? Dave C.

Re: feedback from internal hard drives
Dave, Are some of the drives and the sound card USB? If so, it might be worth making sure they are on separate USB controllers/hubs. Sometimes there is more than one built into a computer, so experimenting with putting them on different USB connectors could be worth your time. With the quality of the sound card, you wouldn't expect this sort of thing, though. If the drives are not USB, where is the controller? If your M-Audio board is in a slot next to a HD or USB controller, I suppose that could cause a problem, but these are not usually separate boards any more and are on the mother board. I saw another response that suggested a ground loop isolator. While I wouldn't discount that as a solution as ground loops can do some strange things, my experience has been that ground loops generally result in at least some 60-cycle hum as well as additional noise. If you're specifically getting hard disk noise without a noticeable amount of hum, it seems as though you are getting leakage into the sound outputs outside of a ground loop path. Also, is there any chance you are running the volume at a low level somewhere because of gain in your speakers and equalizer? If you run your output at a higher electronic volume but you are experiencing some sort of overload, attenuating the output in some other way than turning down the electronic volume control is worth exploring.

Well, that was weird. See below for the finishing of this message, must have gotten distracted. Dave C.

Re: feedback from internal hard drives
you need a ground loop isolater. you can get it at the shack or you use to be able to. It is a long transformer that kills the ground loop. All hook ups are in the box. A cheap solve is to kill the ground on the computer but I didn't want to do that. You can do that by hooking up one of those cheater plugs and not hooking up the ground on it.- Original Message - From: Dave bahr dcba...@gmail.com To: PC Audio Discussion List pc-audio@pc-audio.org Sent: Tuesday, January 10, 2012 12:16 AM Subject: feedback from internal hard drives Hi list, This is a characteristically longwinded message from yours truly. you've been warned!!
