====== CD/DVD howto ======

Alles op de command-line (CLI), uiteraard!

===== ISO bestand maken van een CD/DVD =====

Kijk allereerst hoe de CD/DVD eruit ziet:

<code bash>
michelle@zeil:~$ sudo isoinfo -d -i /dev/cdrom | grep -i -E 'block size|volume size' 
Logical block size is: 2048
Volume size is: 327867
</code>

De getallen die hieruit komen kun je vervolgens invullen in het commando //dd//:

<code bash>
michelle@zeil:~$ sudo dd if=/dev/cdrom of=test.iso bs=<Logical block size> count=<Volume size>
</code>

En als je een nieuwe versie hebt (=> 8.24) van coreutils kan er zelfs een progress-indicator bij:

<code bash>
michelle@zeil:~$ sudo dd if=/dev/cdrom of=test.iso bs=<Logical block size> count=<Volume size> status=progress
</code>

===== ISO bestand naar CD/DVD branden =====

Op de meeste systemen staat het pakket //cdrkit// al geinstalleerd en daarin vindt je `wodim`, de opvolger van het vroegere `cdrecord`. Daarmee kun je eenvoudig een CD bakken. Allereerst is het handig om te kijken of je drive het gewenst type schijfje ondersteund, dus:

<code bash>
michelle@zeil:~$ sudo wodim -prcap dev=/dev/cdrom

Als je er van overtuigd bent dat het goedkomt, dan:

<code bash>
michelle@zeil:~$ sudo wodim -eject -tao speed=8 dev=/dev/sr0 -v -data <bestand>.iso
</code>

Je kunt ook de package //growisofs// gebruiken, dan wordt het als volgt:

<code bash>
michelle@zeil:~$ sudo growisofs -Z /dev/sr0=<bestand>.iso
