In which case it's telling the simple truth that you
don't have a /dev/hdd node?

This threw me so I tried out
hdparm -d /dev/hdd #get dma setting
and
hdparm -d 1 /dev/hdd #set dma
this in an article,
and I can't write above 12X on my writer, it seems the drive receives insufficient
data to sustain the write, while the 20MB buffer in memory is 100% full).
Thanks

Hello
How can I enable DMA on an IDE writer in Linux?
I need SCSI-emulation to use the writer, but that disables DMA.
It seems that my 16X CDWriter cannot write at that speed without DMA. It only
works at 12X, and uses up a lot of CPU resources.
Is there any way to switch DMA back on?
