cdrskin

Limited cdrecord compatibility wrapper for libburn

Purpose:

• Burns preformatted data to CD-R, CD-RW, DVD-R, DVD-RW, DVD-RAM, DVD+RW

Hardware requirements:

Software requirements :

Linux kernel 2.4 or higher

With kernel 2.4 the drive has to be under ide-scsi emulation.

With kernel 2.6 the drive should not be under ide-scsi.

libpthread

is supposed to be a standard system component.

GPL software included:

libburn-0.3.2

(by Derek Foreman, Ben Jansens, and team of libburnia.pykix.org)

transfers data to CD

This program system has been tested on Intel/AMD Linux systems only.
Ports to other usable systems are appreciated. Reports are welcome.

Special features:

• Source code is independent of cdrecord

Commands:

The goal is to provide some of cdrecord's options in a compatible way. This has been achieved quite sufficiently for the needs of backup tool scdbackup and for data CD projects of K3b (see examples). Suitability for audio CD frontends has been improved much and is now being evaluated.
Most DVD types are written in pseudo -tao modes which are very different from the write mode DAO used by cdrecord(-ProDVD). With DVD-R[W] cdrskin can use this write mode, too.
Further enhancements depend on people who can describe and discuss their wishes as well as on the development of libburn.

Get an overview of drives and their addresses:

$ cdrskin -scanbus

$ cdrskin dev=ATA -scanbus

$ cdrskin --devices

Get info about a particular drive or loaded media:

$ cdrskin dev=0,1,0 -checkdrive

$ cdrskin dev=ATA:1,0,0 -v -atip

$ cdrskin dev=/dev/hdc -toc

Make used CD-RW or used unformatted DVD-RW writable again:

$ cdrskin -v dev=/dev/sg1 blank=fast -eject

$ cdrskin -v dev=/dev/dvd blank=all -eject

Format DVD-RW to avoid need for blanking before re-use:

$ cdrskin -v dev=/dev/sr0 blank=format_overwrite

De-format DVD-RW to make it capable of multi-session again:

$ cdrskin -v dev=/dev/sr0 blank=deformat_sequential

Write ISO-9660 filesystem image as only one to blank or formatted media:

$ cdrskin -v dev=/dev/hdc speed=12 fs=8m \

  -sao -eject padsize=300k my_image.iso

Write compressed afio archive on-the-fly:

$ find . | afio -oZ - | \

  cdrskin -v dev=0,1,0 fs=32m speed=8 \

  -tao padsize=300k -

Write several sessions to the same CD or DVD-R[W]:

$ cdrskin dev=/dev/hdc -v padsize=300k -multi -tao 1.iso

$ cdrskin dev=/dev/hdc -v padsize=300k -multi -tao 2.iso

$ cdrskin dev=/dev/hdc -v padsize=300k -multi -tao 3.iso

$ cdrskin dev=/dev/hdc -v padsize=300k -tao 4.iso

Get CD or DVD-R[W] multi-session info for option -C of program mkisofs:

$ c_values=$(cdrskin dev=/dev/sr0 -msinfo 2>/dev/null)

$ mkisofs ... -C "$c_values" ...

Write audio tracks to CD:

$ cdrskin -v dev=ATA:1,0,0 speed=48 -sao \

  track1.wav track2.au -audio -swab track3.raw

Get overview of the cdrecord compatible options:

$ cdrskin -help

Get overview of the non-cdrecord options:

$ cdrskin --help

Read the detailed manual page:

$ man cdrskin

Read about the standard for which cdrskin is striving:

$  man cdrecord

Do not bother Joerg Schilling with any cdrskin problems. (Be cursed if you install cdrskin as "cdrecord" without clearly forwarding this "don't bother Joerg" demand.)

Known deficiencies:

• Appending sessions to unclosed media is restricted to write mode TAO.
• cdrskin -scanbus or --devices hangs for quite a while if there is a CD drive which does not work properly (e.g. because it has individual problems with DMA). So if the superuser gets no result with cdrskin --devices then one should disable DMA with the problematic CD drives (like: hdparm -d0 /dev/hdd ) and try again.
  In severe cases it might be necessary to guess the device name /dev/sgN resp. /dev/hdX of the non-ill burner if it cannot be found otherwise among its ill peers. Alternatively one can guess the address of the ill device, remove rw-permissions and retry the bus scan as non-superuser.

Download as source code (see README):

cdrskin-0.3.2.pl01.tar.gz (570 KB).

The "stable" cdrskin tarballs are source code identical with "stable" libburn releases or with "stabilized" libburn SVN snapshots. They get produced via a different procedure, though.
cdrskin is part of libburn - full libburn is provided with cdrskin releases.

 

Download as single x86 binaries (untar and move to /usr/bin/cdrskin):

cdrskin_0.3.2.pl01-x86-suse9_0.tar.gz, (80 KB),

runs on SuSE 9.0 (2.4.21) , RIP-14.4 (2.6.14) , Gentoo (2.6.15 x86_64 Athlon).

cdrskin_0.3.2.pl01-x86-suse9_0-static.tar.gz, (285 KB), -static compiled,

runs on SuSE 7.2 (2.4.4), and on the systems above.

Enhancements towards previous stable version cdrskin-0.3.0:

• Burnfree enabled by default
• Multi-session burning to DVD-R and sequential (i.e. unformatted) DVD-RW
• Option -toc with sequential DVD-R[W]
• Options -msinfo and msifile= with appendable DVD-R[W]
• Single session DAO write mode with DVD-R[W]

• Multi-track runs with fifo could stall in rare cases

Development snapshot, version 0.3.3 :

Enhancements towards stable version 0.3.2:

• New option --tell_media_space tells the maximum size for the next burn

Maintainers of cdrskin unstable packages please use SVN of libburnia.pykix.org

Download: svn co http://libburnia-svn.pykix.org/libburn/trunk libburn_pykix

Build: cd libburn_pykix ; ./bootstrap ; ./configure ; make

Build of SVN versions needs autotools of at least version 1.7 installed. But after the run of ./bootstrap, only vanilla tools like make and gcc are needed.

 

The following downloads are intended for adventurous end users or admins with full system souvereignty.

Binary (untar and move to /usr/bin/cdrskin):

Many thanks to Joerg Schilling for cdrecord,
and to Derek Foreman and Ben Jansens for creating libburn.
Historic versions based on Derek's and Ben's icculus.org/burn :
cdrskin-0.1.2.0.2.ts.tar.gz
cdrskin-0.1.3.0.2.ts.tar.gz
Very special thanks to Andy Polyakov whose dvd+rw-tools provide libburn with invaluable examples on how to deal with DVD media.

Example how to setup K3b to use cdrskin for burning data CD projects.
(K3b is a GUI frontend which uses cdrecord for CD burning.)
