I thought FDD stood for Floppy Disk Drive

It's most likely the drives causing noise over your speaker line from EMF. The only ways you can combat this is by using digital out to a speaker set that has a digital port, i.e. Creative Inspire...

That's odd. I would expect it to be the other way around. You might want to contact the mb manufacturer.

There is also a significant difference in power consumption and heat dissapation.
