How do you burn a 4GB DVD image under Linux? I always end up with coasters if I try to burn anything with files over 2GB. I've heard this is a problem with a filesystem driver or something.

Any ideas?

4GB DVDs [ot]

Initially, I tried using a minimal Libranet 2.8.1 install with K3b, cdrecord, and growisofs from Sid. DVD coasters were instantaneous.

Then, using SimplyMepis 3.3.1-1, I was able to successfully burn the Knoppix 4.0 DVD on my first attempt. Mepis was using the 2.6.10 kernel, but it was a standard installation of the Mepis CD. And this is on an old 500Mhz AMD K6-2, 256MB machine. I used the Ext3 filesystem on the installs and preserved the /home partition from the Libranet install for use by Mepis (the DVD .iso files were on the /home partition).

I can't tell you why it worked, it just did.

The 2GB limitation applies to individual files you want to burn on a iso9660 filesystem.

In the case of Knoppix image -and this is the magic word: "image"- what you have to do is burn the pre-formatted iso9660 image into the dvd, not burn the iso file as a file.

If you use the program 'growisofs' (part of the dvd+rw-tools package):

bash# growisofs -dvd-compat -Z /dev/dvdrw=knoppix.iso

The line above will do the job (given your burner is /dev/dvdrw). However:

bash# growisofs -dvd-compat -Z /dev/dvdrw knoppix.iso

Without the 'equal' sign you will try to burn knoppix.iso as an individual file inside the dvd iso filesystem. For instance:
bash# growisofs -R -J -Z /dev/dvdrw *.mp3

That will copy your mp3 files to your dvd; if you mount the dvd, you will see your mp3 files.
However, if one of your mp3 files if bigger than 2GB, then growisofs will fail and you will make yet another coaster.

Hope that helps...
