How To Linux Enable DMA for dvdrw cdrw (eg K3b says no DMA)

K3b is known to to do this if you have the DMA bug or not.

You can check by first doing a search for your dvd/cd writer with:(I have put dvdrw)

sudo ls -l /dev/dvdrw

[i]Example:[/i](It tells me that my DVD Writer is /dev/hdd)

richs@lxh:~$ sudo ls -l /dev/dvdrw<br />lrwxrwxrwx 1 root root 3 2008-04-26 16:49 /dev/dvdrw -&gt; hdd<br />richs@lxh:~$<br />

[b]
Then seeing if it has DMA enabled for /dev/hdd:[/b]

sudo hdparm -d /dev/hdd

[b]
And I get this result:[/b]

richs@lxh:~$ sudo hdparm -d /dev/hdd<br /><br />/dev/hdd:<br /> using_dma     =  1 (on)

[b]If yours says DMA is off:[/b]

/dev/hdd:<br />using_dma = 0 (off)

[b]
Turn it on with:[/b]

sudo hdparm -d 1 /dev/hdd

and it should look like this:

/dev/hdd:<br />setting using_dma to 1 (on)<br />using_dma = 1 (on)
