Sebastion, I think this is on the right track - I recall many moons ago
I had exactly the same problem in Windows until I forced DMA on.

However I am having difficulty identifying the cdrom drive letter. Is
it: ls /dev/cdrom
If so I get /dev/scd0
But when I try to see if dma is on: hdparm -d /dev/scd0 I get:
"/dev/scd0:
 HDIO_GET_DMA failed: Inappropriate ioctl for device"
which, to me, says it is not scd0.

Am I doing something wrong?
Many thanks, David
