Somehow I cannot enable DMA for my DVD drive, even if it supports UDMA2 (yes, UDMA2, not MultiwordDMA 2). If I use "hdparm -d1 /dev/dvd" it says it cannot be enabled. And yes I am doing it as root....

Any ideas?
Try hdparm -d1 /dev/cdrom or /dev/cdrom1 if that is your second cdrom. /dev/dvd is only a symbolic link to /dev/cdrom ( ln -s )\
Actually I just tried on mine and it said that

setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)

So I sont really know what the hell is going on.
In Windows my DVDrom is set to UDMA4, but in Linux it says that it supports up to UDMA 4, that is when I type hdparm -i /dev/cdrom, but when I try to enable it it doesnt let me.

I also tried hdparm -d1 /dev/hdd , which is the actuall cdrom device, and same thing.

Does anyone have any suggestions?
