The burning process of optical disc drives consists of creating an image (ISO 9660,TOC/CUE/BIN) and write it to disk. For this purpose, there are several tools that can create images and burn them.

The proposal from september 2014 is now in [[Remastering_the_Install_ISO|Remastering the Install ISO]].

=== Install burning utilities ===
 
<! ex Install programs for ISO 9660 and burning of CD, DVD, or BD - replacing section 1.1>
 
 
 
You need at least one program for creation of image filesystems and one program that is able to burn data onto your desired media type.
 
 
 
Available programs for image creation are:
 
 
 
* {{ic|genisoimage}} from package {{Pkg|cdrkit}}
 
* {{ic|isomaster}} from package {{Pkg|isomaster}} (with gtk2 GUI)
 
* {{ic|mkisofs}} from package {{Pkg|cdrtools}}
 
* {{ic|xorriso}} and {{ic|xorrisofs}} from package {{Pkg|libisoburn}}
 
* {{ic|cdrao}} from {{Pkg|cdrdao}} for TOC/BIN/CUE image
 
 
 
The traditional choice is {{ic|genisoimage}} for ISO 9660 and {{ic|cdrao}} for TOC/BIN/CUE
 
 
 
Available programs for burning are:
 
 
 
* {{ic|cdrdao}} from package {{Pkg|cdrdao}} (CD only, .cue files only)
 
* {{ic|cdrecord}} from package {{Pkg|cdrtools}}
 
* {{ic|cdrskin}} from package {{Pkg|libburn}}
 
* {{ic|growisofs}} from package {{Pkg|dvd+rw-tools}} (DVD and BD only)
 
* {{ic|wodim}} from package {{Pkg|cdrkit}} (CD only, DVD deprecated)
 
* {{ic|xorriso}} and {{ic|xorrecord}} from package {{Pkg|libisoburn}}
 
 
 
The traditional choices are {{ic|wodim}} for CD and {{ic|growisofs}} for DVD and Blu-ray Disk. For growisofs and BD-R see the bug workaround below.
 
For writing {{ic|cue}}/{{ic|bin}} files to CD, install the {{Pkg|cdrdao}} package.
 
 
 
The free GUI programs for CD, DVD, and BD burning depend on at least one of the above packages.
 
 
 
The programs {{ic|genisoimage}}, {{ic|mkisofs}}, and {{ic|xorrisofs}} all three support the genisoimage options which are shown in this document.
 
 
 
The programs {{ic|cdrecord}}, {{ic|cdrskin}}, and {{ic|wodim}} all three support the shown wodim options. Program {{ic|xorrecord}} supports those which do not deal with audio CD.
 
 
 
{{Note|
 
The installed files of packages {{Pkg|cdrkit}} and {{Pkg|cdrtools}} are in conflict.
 
If you want to install cdrtools, make sure that you build a package using [[makepkg]] and install with pacman. Pacman wrappers may resolve to cdrkit instead.
 
}}
 
 
 
=== Learning the name of your optical drive ===
 
(replacing section 3)
 
 
 
For the remainder of this section the name of your recording device is assumed to be {{ic|/dev/cdrw}}.
 
 
 
Check this by
 
 
 
$ wodim dev=/dev/cdrw -checkdrive
 
 
 
which should report "Vendor_info" and "Identification" of the drive.
 
The next guess could be {{ic|/dev/sr0}}.
 
 
 
If no drive is found, check whether any {{ic|/dev/sr*}} exist and whether they offer rw-permission to you or your group.
 
If no {{ic|/dev/sr*}} exists then try
 
 
 
{{ic|1= $ modprobe sr_mod}}
 
 
 
>>> point GUI users to the GUI programs which should handle the following details on their own
 
 
 
=== Erasing CD-RW and DVD-RW ===
 
(replacing sections 4 and 19)
 
 
 
Used CD-RW media need to be erased before you can write over the previously recorded data. This is done by
 
 
 
  $ wodim -v dev=/dev/cdrw blank=fast
 
 
 
Unformatted DVD-RW media need the same treatment before re-use. But fast blanking deprives them of the capability for multi-session and recording of streams of unpredicted length. So one should apply
 
 
 
  $ dvd+rw-format -blank=full /dev/cdrw
 
 
 
{{ic|1= dvd+rw-format}} is part of package {{Pkg|dvd+rw-tools}}. Alternative commands are
 
  $ cdrecord -v dev=/dev/cdrw blank=all
 
  $ cdrskin -v dev=/dev/cdrw blank=all
 
  $ xorriso -outdev /dev/cdrw -blank as_needed
 
 
 
Formatted DVD-RW media can be overwritten without such erasure. So consider to apply once in their life time
 
 
 
  $ dvd+rw-format -force /dev/cdrw
 
 
 
Alternative commands are
 
  $ cdrskin -v dev=/dev/cdrw blank=format_overwrite
 
  $ xorriso -outdev /dev/cdrw -format as_needed
 
 
 
All other media are either write-once (CD-R, DVD-R, DVD+R, BD-R) or are overwritable without the need for erasing (DVD-RAM, DVD+RW, BD-RE).
 
 
 
=== Burning an ISO image ===
 
(replacing section 5)
 
 
 
To burn a readily prepared ISO image run on CD:
 
 
 
$ wodim -v -sao dev=/dev/cdrw isoimage.iso
 
 
 
and on DVD or BD:
 
 
 
$ growisofs -dvd-compat -Z /dev/cdrw=isoimage.iso
 
 
 
The programs {{ic|cdrecord}}, {{ic|cdrskin}}, and {{ic|xorrecord}} may be used on all kinds of media with the options shown with {{ic|wodim}}.
 
 
 
=== Verify the burnt ISO image ===
 
(replacing section 6)
 
 
 
You can verify the integrity of the burnt medium to make sure it contains no errors. Always eject the medium and reinsert it before verifying. The kernel will learn about the new content only by that reinsertion.
 
 
 
First calculate the md5sum of the original ISO image:
 
 
 
{{hc|$ md5sum isoimage.iso|
 
e5643e18e05f5646046bb2e4236986d8 isoimage.iso
 
}}
 
 
 
Next calculate the md5sum of the ISO on the medium.
 
Although some media types deliver exactly the same amount of data as have been submitted to the burn program, many others append trailing garbage when being read. So you should restrict reading to the size of the ISO image.
 
 
$ blocks=$(expr $(ls -l isoimage.iso | awk '{print $5}') / 2048)
 
 
 
{{hc|<nowiki>$ dd if=/dev/cdrw bs=2048 count=$blocks | md5sum</nowiki>|

About the changes on the wiki

Hello. I appreciate your great interest and I agree with some of your requests, especially on clarity. Do not use the main page for experience any changes, because it is a reference page for the entire community. You have to follow a path, discuss the changes, what to change and how to change, apply a "template" to signal to the whole community of possible changes etc. .. Also, any changes must be described on the main page, and in the event of major changes effettualri step by step. Other users can't understand all the changes made. This procedure may seem slow, but considering that it is not a personal wiki, but Community. good weekend.Veleno (talk) 11:00, 27 July 2013 (UTC)

It is well understood that i need approval. Especially since i am an interested party in the field of optical media. The proposed changes are listed at the talk page. What kind of approval do i have to wait for ?
How do i apply a "template" ? (I guess it is a way to expose an implemented proposal for approval.)
Your proposed changes are wide margin, reflecting a possible reorganization of the entire page. You rightly point out that there are gaps and that it can improve the whole. I answered you on the talk. I think you can from your proposal to amend the best across the page, for example, by combining the relative sections of CD and DVD in one section. does not exist a body that approves, you expect a few days, if no one dissenting opinions, you can operate to change. What you propose is not a small change, but I think a broader change that, in my opinion, it should be well organized. that's all. I apply a template that links to the discussion. ;) Veleno (talk) 11:37, 27 July 2013 (UTC)
