Another error is that the man page falsely implies that the -format option can be used to forcibly reformat a DVD+RW medium. In reality, this is impossible even when using the -force option. The -format option can only be used on an unformatted DVD+RW disc. Rawhide's wodim man page is the same. My Rawhide is virtual and I don't seem to be able to test this properly, but the odds are that Rawhide has the same issues. Someone with Rawhide on real hardware and some unused DVD+RW discs, please test this and then bump the Version to Rawhide if the problems still exist there. Thanks. It also appears that if a DVD+RW is partially formatted (using "dvd+rw-format /dev/dvd", for example) and you use wodim to write past the point where the disc is currently formatted, it seems to complete successfully, but reading will fail. My father experienced this when writing a large (several hundred MB) tarball with wodim. The write completed without error but attempting to read it using star failed with a checksum error. So the problem seems to be that wodim is incapable of handling automatic formatting at all - and if the disc is partially formatted, and it writes past that point, it won't even indicate that there's a problem. The only way to be sure that a wodim write will work is if the ENTIRE disc is formatted IN ADVANCE. What you see is just a result from the fact that some non-cooperative downstream packagers bastardized a working program and created a buggy fork. The man page was taken from cdrtools and it is correct for the software it was taken from. In the fork, the working DVD support code was ripped off and replaced by something half baken..... BTW: It does not make sense to discuss things like this as the fork "cdrkit" cannot be legally distributed - it is in conflict with the copyright law. The obvious solution is to use recent original software. The original software has no legallity or license problem and works as documented. Verified that wodim's -format option can't be used in Rawhide either to fully format a partially formatted DVD+RW, even using -force. I don't have any unused DVD+RWs to verify that the original problem also exists in Rawhide, but all things considered I think it's safe to assume it does. Bumping the Version to rawhide. wodim is completely unmaintained since May 6th 2007, don't expect to see any fixes anytime soon as long as Redhat continues to distribute wodim instead of the original software. Nonsense, the latest commit to cdrkit upstream was just 3 weeks ago. And BTW, the best tool to burn DVDs, especially DVD+RWs, is growisofs, packaged in the dvd+rw-tools package. See also: http://fy.chalmers.se/~appro/linux/DVD+RW/ http://fy.chalmers.se/~appro/linux/DVD+RW/-RW/ (especially the first Q&A) I know about growisofs, but have a backup script that uses wodim, due to 1) the fact that it has a zero-padding option, and 2) behaves better as far as automatically pulling in and ejecting the disc. I couldn't figure out how to get the same behavior using growisofs. The downside is that I have to make sure that any discs used are fully formatted in advance, due to this bug. This is nonsense. Pretending some some pseudo activities from time to time does not verify a maintained project. There are still more than 100 different serious bugs in the various bug tracking systems of the Linux distributors. There are even more than 60 serious bugs in the Debian bug tracking system. The majority of the bugs in question are present since the fork was created and nobody cares to fix them even though most of the bugs are easy to fix. Please do not try to mess around with the users and and finally admit that all known problems with the fork will disappear if you upgrade to recent original software. And BTW: cdrecord is one of the _very_ first DVD writing programs. Cdrecord supports to write DVDs since February 1998. The original cdrecord of course supports to write DVD-RWs since a long time. The problem with wodim is that the working DVD support that comes with cdrecord has been ripped off and replaced by something half baken.

I recommend you to simply just the original cdrtools. This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle. Changing version to '12'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping This bug appears to have been reported against 'rawhide' during the Fedora 13 development cycle. Changing version to '13'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component. Created attachment 499538 [details] proposed patch This patch implements auto-formatting on maiden DVD+RW. It can be tested in: http://koji.fedoraproject.org/koji/taskinfo?taskID=3078215 I'll try to discuss it with upstream before applying in Rawhide. Created attachment 499635 [details] proposed patch This is a new patch, because the previous one didn't work properly. A new test build is available here: http://koji.fedoraproject.org/koji/taskinfo?taskID=3078796 cdrkit-1.1.11-8.fc15 has been submitted as an update for Fedora 15. https://admin.fedoraproject.org/updates/cdrkit-1.1.11-8.fc15 cdrkit-1.1.11-3.fc14 has been submitted as an update for Fedora 14. https://admin.fedoraproject.org/updates/cdrkit-1.1.11-3.fc14 Package cdrkit-1.1.11-3.fc14: * should fix your issue, * was pushed to the Fedora 14 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing cdrkit-1.1.11-3.fc14' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/cdrkit-1.1.11-3.fc14 then log in and leave karma (feedback). cdrkit-1.1.11-3.fc14 has been pushed to the Fedora 14 stable repository. If problems still persist, please make note of it in this bug report. cdrkit-1.1.11-8.fc15 has been pushed to the Fedora 15 stable repository. If problems still persist, please make note of it in this bug report. You are publishing software of questionable legality: http://cdrecord.berlios.de/private/linux-dist.html#violations There is non-working DVD-support in this wodim and there is missing BluRay support. wodim is a cdrecord version from September 2004 with DVD-support removed and with Debian specific bugs added. Do not expect it to be usable in 2011. Please upgrade to recent original software. The original software grants you proven legality and is decently maintained.

(In reply to comment #11) > I recommend you to simply just the original cdrtools. (In reply to comment #22) > Please upgrade to recent original software. The original software grants > you proven legality and is decently maintained. As I've written in bug #709902, I don't think it is necessary to say the same thing several times per every cdrkit bug. Many similar ideas were already said in bug #507108. As long as RedHat distributes the illegal cdrkit instead of the legal original software and as long as RedHat legal denies even to talk about this problem, what other opportunity do I have to enclourage you to start a discussion that ends in RedHat becomming legal again? |
Description of problem: If one tries to write to a previously unused DVD+RW disc with wodim, one gets an error saying the disc is unformatted. But the wodim man page claims this is supposed to happen automatically.

[vic@compaq-pc tmp]$ From the wodim man page: -format Format a CD-RW/DVD-RW/DVD+RW disc. Formatting is currently only implemented for DVD+RW media. A ’maiden’ DVD+RW media needs to be formatted before you may write to it. However, as wodim autodetects the need for formatting in this case and auto for- mats the medium before it starts writing, the -format option is only needed if you like to forcibly reformat a DVD+RW medium. Version-Release number of selected component (if applicable): wodim-1.1.9-6.fc11 How reproducible: always Steps to Reproduce: 1. Attempt to write to a previously unused DVD+RW disc using wodim. Actual results: "medium not formatted" error, but man page says it's supposed to be formatted automatically. Expected results: Either medium should be formatted automatically, or man page shouldn't claim it will be.
