I was looking at the command to burn iso image to a dvd. But I couldnt get the name of the device. In the /dev/ I could see cdrom,cdrw,dvd,dvdrw. I am using debian.

When I gave the command, I got the following output

dd if=debian-6.0.7-i386-DVD-1.iso of=/dev/dvdrw 
dd: opening `/dev/dvdrw': Read-only file system

You can't burn a cd with dd. – Ulrich Dangel Mar 19 '13 at 9:27

You can't use dd this way (it might work for DVD-RAM though). What you are looking for is growisofs - (the main) part of dvd+rw-tools.

growisofs -Z /dev/dvdrw=image.iso

Using dd command you can not write DVD. You can write DVD using growisofs command.

First you have to create ISO Using dd command like

dd if=/dev/dvd of=my_test.iso bs=2048

Then write DVD Using this command

growisofs -dvd-compat -Z /dev/dvd=my_test.iso

I believe growisofs uses dd, so the original command could work. My example uses a 22G image to bluray. Here is the output of growisofs using the dry-run option:

growisofs -dry-run -speed=1 -Z /dev/sr0=/snd/BDSV_3E.iso


Executing 'builtin_dd if=/snd/BDSV_3E.iso of=/dev/sr0 obs=32k seek=0'

You can experiment. I suggest using cheaper DVDs or CDs
