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. Mar 19, 2013 at 9:27
  • I have been burning iso images to DVD's and CD's for more than 35years. It is only in recent (past 6-7 years) incarnations (versions) of dd that it fails to write on blank media. So, the driver has been modified to not allow dd to write on blank media. Since other apps (like k3b) CAN write to blank media, I suggest that users hack the source code of such gui apps and look at what they do to enable writing to blank media, and create a dd-like command to get back the old functionality of dd.

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
