I am trying to enable DMA on my burner/cdrom/dvd combo drive. I don't have a /dev/dvd so I have just been mounting the dvd like so. mount /dev/cdrom /mnt/dvd and I can play DVDs just fine. However, when I do a /sbin/hdparm -d1 /mnt/dvd/ I get the following: /mnt/dvd/ not supported by hdparm How do I get DMA working? -ryan
