cdrecord

Hi,

I have used cdrecord to burn a few .iso disc and in general these are fine. But I was curious to know what kind of parameters oldhand longtime users like to use.

I mean off the bat for burning iso - I found using (for example)

Code:

cdrecord -dummy -v speed=6 dev=/dev/scd0 kubuntu-7.10-dvd-i386.iso

does a good job of burning the dvd (after testing first with -dummy) at a reasonable speed (x6 speed) and provided me plenty of information.

I used the line below to determine the speed (which gave me x6 write). It's actually 16x write but not to argue!

Code:

cdrecord dev=/dev/scd0 -prcap

So, what extra parameters or switches do regular users find useful that I may have overlooked in the man file? I did a good read but felt I extracted enough above for the purpose. I did see -V (which gave more info but with a warning).

Actually one thing I spotted from the log was:

Code:

WARNING: Phys disk size 2244045 differs from rzone size 2298496! Prerecorded disk?
WARNING: Phys start: 196608 Phys end 2440652
Blocks total: 2298496 Blocks current: 2298496 Blocks remaining: 54451

This was on the 2nd run after the dummy run was tested. The dvd disc was blank and never used. I'm guessing the cdrecord was making some assumptions that some blocks were already written to. Testing the dvd it was fine.

One improvement I can think of here is writing the output to a log file? Like...

Code:

cdrecord -dummy -v speed=6 dev=/dev/scd0 kubuntu-7.10-dvd-i386.iso <2/tmp/cdrecord_log.txt

Apologies, if I got the redirect wrong, as I haven't really covered that yet.

Here's some tidbits ...

Code:

To burn an .iso image to DVD:
growisofs -dvd-compat -Z /dev/hd*=image.iso

To make a CD from the .iso image:
cdrecord -v -eject driveropts=burnfree dev=/dev/hda /path/to/file.iso
(may need to add -overburn if the image is larger than the CD)

To erase a CD-RW:
cdrecord -v dev=/dev/hd* blank=fast

To blank a DVD+RW:
growisofs -Z /dev/dvd=/dev/zero
dvd+rw-format -force -lead-out /dev/dvd

To burn an image of a CD to the hard drive:
dd if=/dev/hda of=namethecd.iso

To make and save a copy of a data CD:
gzip < /dev/cdrom > name-it.iso.gz

To create a CD .iso image from a directory:
mkisofs -r dir | gzip > cdrom.iso.gz

To view/edit the contents of an .iso image:
mount -oloop cdrom.iso /mnt/dir
(mount the cdrom image at /mnt/dir)

Rip audio tracks from CD to .wav files in current directory:
cdparanoia -B
(you might need lame installed for this, also)

To make and audio CD from all .wav files in current directory:
cdrecord dev=/dev/cdrom -audio *.wav

To make .ogg files from .wav files:
oggenc --tracknum='track' track.cdda.wav -o 'track.ogg'

To make .mp3 files from .wav files in current directory:
for i in *.wav; do lame "$i" "`basename "$i" .wav`".mp3; done
(you will need lame installed for this)

To copy from one drive to another:
cdrdao copy --device /dev/hda --source-device /dev/hdc
(This will copy a VCD when I couldn't find anything else to do that job)

Where you see /dev/hd* you should substitute your drive letter.

Thanks - you obviously know your cdrecord.

Interesting about growisofs - I never used it - must be fairly recent. Must try this for next time!

Code:

To burn an .iso image to DVD:
growisofs -dvd-compat -Z /dev/hd*=image.iso
