Same controller?  IDE?

I use two IDE controllers, the fastest drives go on the best controller.
The CD-R and DVD go on the lower end - usually the motherboard controller.
I place one IDE per channel, this allows dma to be set (CD-R's will 
restrict a whole channel)

Is dma and IO32 enabled on the IDE drives?

use hdparm to check.

I had an issue with onboard IDE controllers not allowing dma mode, even 
though there were only hard drives on the controller.
This was due to the drivers compiled as modules - compiling the ide 
drivers into the kernel allowed the dma to be enabled.

hehe firefox can be a pig if you open the right site. :)
