Pat - Thanks for the clarification. I'd actually intended to use Yast2 to set the DMA mode so it lasted through reboots. I always knew you could do that for ide devices. My problem was that I wasn't sure of the relationship between scsi emulation and ide devices. I also didn't know which particular device represented /dev/sr1. By the way, what's all this about "reboots" - this is a Linux system. Uptime 72 days and counting! Anyway, thanks to everyone who gave me advice.

Kenneth, What Ken was trying to point out in his mail was not so much how to fix your problem as how to make it a permanent fix. If you never reboot, just issuing the command hdparm will get it going, as you found out and it will last, until your next reboot. So if you want it to have DMA turned on with each boot, then go to the file and add /dev/hdd to that line.
# # force dma to "on" for the following ide devices # DEVICES_FORCE_IDE_DMA_ON="/dev/hdd"
