It is supposed to do multi-session on DVD+R if you do not use options -dvd-compat or -dvd-video. Reason 1: I read the man page and I did exactly what it stated, and it wasn't working for me. Please see my current posting (5 days old) on ubuntuforums - http://ubuntuforums.org/showthread.php?p=4288486 No body could really help me with this issue. But as you will see I didn't stop there.

Re: Help: Burning multisession DVD+R with cdrecord 2.01.01a37
Hi, > http://ubuntuforums.org/showthread.php?p=4288486 You have a problem with the formatter program genisoimage, a clone of mkisofs. growisofs uses mkisofs (or a clone of it) as formatter. It obtains multi-session info from media, operates mkisofs accordingly, and directs the resulting image to media by its own DVD capabilities (which are ecxellent, btw). > Step 2 - Append each additional track: > I moved an existing file out of the current directory > and into another: /media/sdc1/backups/rt/2008/02/ rt.2008.02.06.tgz > and added a new file: /media/sdc1/backups/rt/2008/02/ rt.2008.02.07.tgz > ... # growisofs -M /dev/hda -R -J /media/sdc1/backups/rt Your idea is great. Greater than genisoimage can fulfill currently. You cannot delete or rename a file by genisoimage multi-session. genisoimage will not examine a directory tree for changes and update it in the ISO image. Looks like it rather refused to overwrite some directory. Or it is just a bug. Hard to say. You should nevertheless be able to add a new file to an existing directory. Try whether this works as second session: growisofs -M /dev/hda -R -J /media/sdc1/backups/rt/2008/02/rt.2008.02.07.tgz (Use fresh media. Not those from previous experiments.) With cdrskin you would have to do what is usual with CD-R and multisession: c=$(cdrskin dev=/dev/hda -msinfo 2>/dev/null) mkisofs ... -C "$c" -M dev/hda ... | cdrskin dev=/dev/hda -multi -tao ... The libburnia project is quite near to releasing an integrated multi-session tool which would be able to do parts of your above sketch. For the remaining days - or if you have had enough adventure - i would advise you to either use above cdrskin gesture or to go back to growisofs which will do the same more conveniently.

Hi, > cdrskin: error while loading shared libraries: libburn.so.4: cannot open > shared object file: No such file or directory Sigh, this is what i earn if i try to cope with dynamic libraries. The packagers want is so. As a shortcut, try the static 32 bit binary which is the only file in http://scdbackup.sourceforge.net/cdrskin_0.4.2.pl00-x86-suse9_0-static.tar.gz Now for the failed source installation: If you downloaded the source tarball http://scdbackup.sourceforge.net/cdrskin-0.4.2.pl00.tar.gz followed the installation instructions in http://scdbackup.sourceforge.net/README_cdrskin especially this step before make install : cdrskin/compile_cdrskin.sh which should avoid .so dependencies on libburn. Well, then you found a bug in our autotools setup. Somehow make install installs not the standalone version and fails to install the dynamic library. autotools ... shoot your own foot for free. Nevertheless, after cdrskin/compile_cdrskin.sh there should be a file cdrskin/cdrskin of at least 500 kB size. Is that one able to execute cdrskin/cdrskin -version If so, then find out where cdrskin is found currently by the shell: which cdrskin If that is not /usr/local/bin/cdrskin then we have a plausible culprit for the mess-up. Whatever, copy as superuser the file cdrskin/cdrskin over the address reported by the which command. Afterwards try: cdrskin -version -- To the bystanders: I would appreciate any hint about what went wrong with my autotools installation setup. I mean, it is plausible that it pulls a dynamic cripple out of some cache after a standalone binary was compiled by external means. (It worked in my test ... well, that can have been an acident.) But why does it not properly install libburn.so.4 and makes it ready for use ? See for the autotools configuration before ./bootstrap: http://libburnia-project.org/browser/libburn/tags/ZeroFourTwo Have a nice day :) Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Even before, the majority of the changes have been caused by the replacement of the original build-system by something else and this was a really strange act, see: http://cdrecord.berlios.de/private/linux-dist.html#license for more information. It seems that the people who are sesponsible for "cdrkit", finally found that they don't have the time nor the skills to work on the source. There are many open bug reports against cdrkit from various Linux distributions and even simple to fix bugs have not been fixed since more than 9 months. > Reason 3: I see there is a really big mess right now with this whole > wodim - cdrecord - growisofs - genimageiso, whatever.

Oh, man all of you guys are awesome! Thanks. I'm still having issues, but I feel I have to apologize for not replying fast enough here (^_^). Thanks for all of your help. I don't know where to start, so I'm going to try and answer everyone on this post: Thomas Schmitt: There nothing wrong with your auto-install, don't worry about it. I am currently using Ubuntu 7.10 Gusty Server Edition. Doing a ./configure; make; make install is all that you need ( I think. I'll try it again without installing libburn seperately). Since I'm using ubuntu, and compiling from source, after all is done run the "ldconfig" command, and it will install libburn.so.4.

Thanks (^_^) Please note that Thomas (in contrary to the people who created the wodim fork) writes own software but unfortunately his software is non-portable and only works on Linux. All my software works on all known platforms. Well, Linux is the post popular open platform, but Solaris is the second popular open platform and Thomas software does not work on Solaris. Also note that even the idea of writing a CD/DVD writing _library_ is based on a privileges missconception that is only present on Linux. Even Linux only allows a limited subset of what cdrecord supports if you do not have root privileges. The idea of having such a library comes from GUI people that like to _include_ the CD/DVD writing features into their GUI, but they do not understand that this cannot be done on all platforms but Linux for security reasons. On Linux it only works in a limited way because Linux ignores some security issues. There exist several similar attempts on writing libraries for tasks that cannot exist on platorms other than Linux because other platforms better check privileges/security. All these other libraries are derivates from cdrtools code and all also have license problems. This makes a lot of functionality seen in GNOME on Linux illegal because of license violations and non-portable because of privileges violations.

This makes a lot of functionality seen in Because of the "license" attacks from some Debian outsiders, it seems that I need to go more in depth with this issue to avoid confusion: - The original code from cdrtools has no license problems - The libraries in question give license problems for three different reasons: - A few projects took code from Heiko Eißfeldt that never has been published under GPL and claimed this code is under GPL. This is an obvious license/copyright violation. It was true for cdrdao and it is still true for e.g. GNU-vcdimager. - libcdio e.g. took code from cdrtools that was under "GPLv2 _only_" and changed the license to "GPLv2 or any later" without permission from the Authors. - libcdio and similar libs that are under GPL but are intended be used by LGPL libraries (like e.g. libgstreamer). As GPL and LGPL are incompatible (LGPL code may not call GPL code), this construct results in an implicit license violation "originated" by potential distributors of e.g. Linux, *BSD or Solaris OS-distributions. Distributors that ask lawyers and take care of license problems (like e.c. Sun) for this reason removed libcdio from their distribution.

Re: Help: Burning multisession DVD+R with cdrecord 2.01.01a37
Hi,
Joerg Schilling:
> What do you understand by "not closed"?
Again quoting from the description in MMC-5,
4.3.6.2.3 (Models, DVD, DVD+R):
"If the user wishes to disallow further writing after
the session is closed, it is possible to select a close
function to finalize the disc."
This is not done if cdrskin is run with option -multi.
If finalization is desired, i use
"CLOSE SESSION, 101b, Finalize with minimal radius"
> Please note that Thomas (in contrary to the people who created the wodim
> fork) writes own software
To be exacting:
The start of libburn was made by Derek Foreman and
Ben Jansens. They provided CD SAO and CD RAW.
Our team began to carry on about 1.5 years
ago and i added CD TAO. The handling of DVD is
inspired by studying the sources of growisofs
and the SCSI specs.
So libburn and cdrskin are deliberately independent
of cdrtools. A true technical alternative, although we
all cook with the same kind of water: SCSI subsection MMC.
> unfortunately his software is non-portable and only
> works on Linux.
This is the consequence of having no potential
users on other systems. The system dependencies are
separated from the portable code. I could learn from
growisofs how to operate the SCSI tunnels of other
systems ... but without a real test user this makes
not much sense.
We got an unused and unmaintained FreeBSD port. Shrug.
> even the idea of writing a CD/DVD writing _library_
> is based on a privileges missconception that is only
> present on Linux.
Before i begin to defend the library concept, a personal
statement: I hate .DLLs. Even if they are called .so.
We have seen it yesterday. They make life complicated.
But on the first hand, libburn is re-usable code with
a defined API and an upwards compatible ABI. Whether you
link its .o files directly, as static library or as dynamic
library, that is mainly a packager/sysadmin detail.
During development i compile with shell scripts which
produce debuggable standalone binaries.
> The idea of having such a library comes from GUI people
Yeah. But it needed a command liner to get it out
of the baby bed. :))
My motivation was my backup tool which depended
heavily on cdrtools and runs on Linux. There is
no love between cdrtools and Linux.
libburnia wants to be nice and cuddly with Linux.
Happy Valentine's Day, Darling !
We now got a workable libisofs, too.
Author is Vreixo Formoso.
Since about a month, i can do all of my backups
without needing mkisofs or genisoimage any more.
That is a big progress for any use case where
the original files cannot be frozen by a shutdown
or a snapshot.
With mkisofs the backups fail when files vanish
during image generation. New libisofs is willing to
go on in such a case - if the application has set
an according tolerance threshold.
The library concept shows its strengths by the
fact that our new ISO 9660 formatter app has
inherited own burn capabilities at very low
programming cost.
The capability to do multi-session without
juggling with a burn program and a formatter
program is very convenient. See growisofs.
> You need root privileges for cdrecord
For libburn, you need rw-access to the block
device file on Linux 2.6 resp. to the generic
device (sg) on Linux 2.4.
No problem ever has been traced back to missing
root privileges.
Possibly we inadvertedly restrict ourselves to what
the kernel programmers deem safe and reasonable
... or maybe it is just the power of love {:)
Have a nice day :)
Thomas

Hi, > > MMC-5 4.3.6.2.2 Bill Davidsen: > Thanks, I saved that bit so I can quote it Overview of media and write types: CD-R[W] - Packet fixed. Could allow non-seamless writing without burn-proof. Used for formatted Mt.Rainier media which allow random access writing. - Packet variable. Few known. Generalization of TAO. - TAO. One single variable sized packet forms the track. - RAW. One single data stream forms the whole track. You have to provide format entrails of the sectors. Several subformats with different parameter sets exist. - SAO. One single data stream forms the whole session resp. the whole disc. You have to announce the track layout and formats by a previously submitted form, the cue sheet. TAO is capable of multi-session. SAO can be used for a first session. If the disc is not finalized afterwards then TAO sessions can be appended. Audio versus data is a property of sectors, not necessarily of a whole session. To mix audio and data sectors in one track seems not to be possible (maybe via RAW ?). Many advanced CD features are not published but in the "Rainbow Books". Thus we got much room for confusion and speculation. DVD-R[W] - Packet fixed 32 kB (alias Incremental Streaming). Can be used for multi-session if disc is not finalized after the session. Fast blanked DVD-RW cannot do this mode. Use cases similar to CD TAO. - Disc-At-Once. Single track of fixed size. Disc always gets finalized. Use cases similar to single-track CD SAO. - Formatted. Fixed size packet mode similar to Mt.Rainier resp. DVD-RAM. "Rigid Restricted Overwrite" means you have to write in 32 kB blocks to 32 kB aligned addresses in contrast to 2 kB on DVD-RAM. See multi-session remark about DVD+RW. DVD+R- Packet fixed 32 kB. Can be used for multi-session if disc is not finalized after the session. DVD+RW - Formatted. Fixed size packet mode similar to Mt.Rainier resp. DVD-RAM. Writing is performed in 32 kB blocks but the drive will accept and handle 2 kB aligned requests with poor performance. No session history on media. Thus no multi-session unless the session can be recognized by data content (growisofs). DVD-RAM - Formatted. Fixed size packet mode (original Mt.Rainier ?) with 2 kB granularity and write success verification. In default mode, bad sectors are handled automatically and slowly. The luxury and pedantic version of DVD+RW. All DVD media are restricted to data blocks. No Audio. No RAW. DVD-R[W] are quite similar to CD-R[W]. DVD+RW and DVD-RAM want to be hard disks. DVD+R seems to strive for a new kind of multi-streaming: You can have open 16 tracks at once. Pointers to information sources (mainly in MMC) can be found in http://libburnia-project.org/browser/libburn/trunk/doc/cookbook.txt?format=raw Sponsors wanted for exploration of DVD DL and BD media. > Supported modes: TAO PACKET SAO SAO/R96P SAO/R96R RAW/R16 RAW/R96P RAW/R96R > I really wish I fully understood all of the modes with "/" I can only guess here. R96P, R96R, R16 depict parameter sets for raw sectors. These extra data get added to the paylod by the burn program so they can be inserted into the sector entrails. SAO/ and RAW/ probably depict multi-track and single-track sessions. LAYER_JUMP is a term from DVD DL specs.

Clearly some drives offer one or the other, some both, and some odd things like: Identifikation : 'DVD A DH20A4P ' Supported modes: TAO PACKET SAO SAO/R96P SAO/R96R RAW/R16 RAW/R96P RAW/R96R LAYER_JUMP I really wish I fully understood all of the modes with "/" but I have never needed them so it's just curiosity for now. -- Bill Davidsen <[EMAIL PROTECTED]> "Woe unto the statesman who makes war without a reason that will still be valid when the war is over..."

Hi, > cdrskin dev=/dev/scd0 -v padsize=300k -multi -tao track_02.iso > ... > I finally unmount, eject the disc, re-inject the disc, remount and bingo: Good news: cdrskin works as it should. Intermezzo: growisofs would do about the same for you. You would have to talk it into using the mkisofs which cooperated properly with cdrskin. man growisofs proposes: export MKISOFS=/path/to/trusted/mkisofs But next i get a sour look on my face: The block device driver and cdrskin are not in sync. Ejecting and reloading discards the i/o cache. So i assume that cache was outdated after cdrskin has ended its work. I know this effect from Linux 2.4 and CD images smaller than 1 MB. Obviously it is present in your Linux with much larger images. To have cache and media out of sync is unhealthy. The current state is not safe without ejecting. So add option -eject to your cdrskin command for now. Well, 18 MB is ridiculous small for a DVD session. DVD+R allows 153 sessions. Even with some overhead between sessions it will be only 3 GB then. So i urge you to make experiments with generous padsize= . I would try values like 20m or 100m. You should also make experiments with growisofs. Maybe it knows a trick ... if so: tell me. Any bystander here who knows how to refresh the i/o cache of /dev/sr0 ? Best without the need to be superuser. :)) Have a nice day :) Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Re: Help: Burning multisession DVD+R with cdrecord 2.01.01a37
Any bystander here who knows how to refresh the i/o cache of /dev/sr0 ? Best without the need to be superuser. :)) A quick look at the generic CD-ROM layer code in 2.6.24 suggests that issuing an ioctl with a code of CDROMRESET may very well do the job. This code path calls invalidate_bdev() on the device, and then calls the drive-specific reset routine. You could also try an ioctl with a code of BLKFLSBUF, which appears to do an fsync_bdev() followed by invalidate_bdev(). This one is checking for capable(CAP_SYS_ADMIN) and so might require superuser privileges and then some. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Sorry I haven't responded back sooner. I needed to switch gears and work on my employer's email/open ticket project. I was able to continue on yesterday late afternoon. Good news and same news. I was able to burn a multi-border DVD+R using cdrskin. The down side, it still does this funny thing where the drive only reads the last track mounted until it the disc is ejected, and then re-injected back into the system.

Hi,
Eric Wanchic:

Urm ... how to say it ... hem, hem:
Better -eject or use xorriso.
-
I made experiments on my SuSE 10.2 (one year old
distro on 3 month old computer). There is a quite
reliable ill effect with burning CD-RW and reading
it without eject-load cycle.
It is not the same as described by Eric, but it is
as well a reason to eject media after burning
(unless one circumvents the block device for reading
as it has to be done for writing).
The problematic procedure on my system is this:
- insert a blank CD-RW into /dev/sr1
- burn 40 MB as first session
ioctl(CDROM_MEDIA_CHANGED)==0 :(
- checkread via dd if=/dev/sr1 : ok 40 MB visible
and identical to image.
- blank again
ioctl(CDROM_MEDIA_CHANGED)==1 :)
- burn 125 MB as first session
ioctl(CDROM_MEDIA_CHANGED)==0 :(
- checkread via dd if=/dev/sr1 : yields 40 MB
If i do not eject, then i always get 40 MB from
the block device buffered i/o.
This does not depend on the burn program or on
the user id.
cdrecord as superuser has the same effect as
cdrskin as desktop user. wodim the same.
It is not their fault.
growisofs transport.hxx contains this software haiku:
1. int is_reload_needed (int same_capacity)
2. { if (same_capacity && ioctl (fd,0x1261,0) == 0) // try BLKFLSBUF
return 0;
else
3. return ioctl (fd,CDROM_MEDIA_CHANGED,CDSL_CURRENT) == 0;
}
I understand the poet's intention as follows:
1. is true if the readable amount of data before burning
is the same as after burning. (see growisofs_mmc.cpp
and growisofs.c)
2. only then try to flush the buffers and omit eject-reload.
3. if the readable size changed (grew ?) then check whether
the media is considered considered changed and in that
case omit eject-reload.
Umbrella open
chase away obscuring clouds
if not sun smiling.
I watch CDROM_MEDIA_CHANGED in libburn now and i try
BLKFLSBUF in my local development version.
For my desktop user it returns -1 and errno 13 "Permission denied".
For root i get errno 38 "Function not implemented". Grmpf.
--
One needs reliable and up-to-date block device reading
if one uses mkisofs or genisoimage for multi-session.
So in this case i see no other way but ejecting and
loading the media between sessions.
This can be done either by shell commands "eject" resp.
"eject -t" or by "cdrskin ...burn-run... -eject" resp.
"cdrskin dev=/dev/sr0 -atip >/dev/null 2>&1".
Only xorriso is immune against the problem. I did never
experience any image read failure in the last three months
of testing. It would show up clearly, because after each
session commit in dialog mode it reloads the result image.
I have now written 600 MB in four sessions, the block device
shows me the first 40 MB of the first 150 MB session,
and xorriso correctly shows me the ISO directory tree
which is stored beginning at 170988s = 334 MB.
So as long as you do not want to restore the backup
that long the tray would not need to be ejected.

Have a nice day :)
