EMI/RFI interference from hard drives...need help


I am getting interference from my hard drive and it bleeds through the sound card every time the hard drive is accessed. Has anyone else had this problem before? Advice is appreciated.

I put about 1/4 page of stealth fabric that covered two sides of the six possible sides of the 300 watt power supply. I also put a 2" square of stealth laying loosely on top of my sound card.

I still use the card deluxe from digital audio labs.

A bit off topic, but anyone use a high end sound card that doesn't have a lot of dongles? I wonder if any expensive $300 or greater soundcards work without adapter dongles.
i fixed the problem by switch pci slots around so the soundcard has a lower irq than the ide controller.
