Then it is not exactly the same problem as with the DRW-24D5MT of Mauro Sacchetto and my BW-16D1HT as of Debian bug 998718.

Keep in mind that in the Debian bug scenario Brasero's bad read attempt spoiled the two ASUS drives until they got a power-off-on cycle. If the drive is built into the computer this means a power-off-on cycle of the computer, i fear. (I have mine in a USB box. That eases the problem.) It was enough to show Brasero a CD burnt with wite type TAO to let the drive go mad. It was not necessary to make a burn attempt. The only workaround was to blank CD-RW by other programs before giving them to Brasero for being re-written. Unfortunately TAO is the write type used by Brasero itself. Other programs may choose SAO with the consequence that those CDs don't let the drive go mad, even when they get shown to Brasero.

Hi, the error message stems from the burner drive and was forwarded by libburn to Brasero. Strangely the code ASC=21 , ASCQ=04 is not specified in in the SCSI specs for optical drives (MMC). In the overall error code list https://www.t10.org/lists/asc-num.htm it is listed for other device classes as 21h/04h DZ UNALIGNED WRITE COMMAND I know this error code from https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=998718 with Drive type : vendor 'ASUS' product 'DRW-24D5MT' revision '2.00' Brasero crashed at that occasion before it could start to write. The indirect reason seems to be a bad READ CD command which Brasero emitted on its own (i.e. not via libburn). It brings the firmware of two ASUS drives to a state from where it throws that error code. (Mine is a BW-16D1HT with firmware 1.01.) It happens only with CD media which were written by write type TAO. So (assuming that the drive has address /dev/sr0): - What is the vendor, model, revision of your drive. You may obtain it from the empty drive by xorriso -outdev /dev/sr0 -toc | grep 'Drive type' - Do you experience the problem with CD-R or CD-RW media ? If so: - What happens if you use a writable DVD medium instead ? - Does it help to blank the CD medium before using it with Brasero: xorriso -outdev /dev/sr0 -blank as_needed - Do you experience the problem with other GUI programs like K3B or Xfburn ? - Do you experience the problem with a run of xorriso ?

[Bug 1896804] Re: CD/DVD drive detected as read only, command line and GUI programs
Hi, sorry for your drive. But good for Linux burn programs that MS-Windows does not know something essential about drive error messages which we Linuxers don't know. > the srange this is that if you use the Disks program in utilities. That's probably a message from the kernel via systemd and lsblk. Although the Linux kernel is willing to apply disk write commands to overwritable media in optical drives, it mostly treats them as CD-ROM. That's why there are burn programs in userspace which send SCSI commands directly to the drive, circumventing the buffered block device layers of the kernel. And that's why much of the kernel's cdrom and sr driver code had few motivation to follow the technical evolution from CD to DVD and BD. (The relation of cdrom and sr is funny enough. cdrom was meant as abstraction of the various hunchbacked CD drives of the mid 1990s with proprietary controllers and command sets. sr represents for cdrom the then rare SCSI drives which are now the only survivors at PATA, SATA and USB. Meanwhile code execution hops forth and back between both drivers which are actually only one.) Well, now i have to think what to do with my code change to tolerate all 6,28,XX error codes ...

Hi, well, at least we got over the strange error code. > libburn : SORRY : Timeout exceed (3 ms). Retry canceled. > libburn : SORRY : Command: READ DISC INFORMATION #63,[2 04 00] : 51 00 > 00 00 00 00 00 00 22 00 : dxfer_len= 34 The command READ DISC INFORMATION was retried 63 times. The last failure was because of a timeout of 30 seconds. The failed command does not cause much effort in the drive. It is just an inquiry about the overall state of the loaded medium. Normally it is done within less than a millisecond. The drive seems to have announced that there is a medium loaded. Else libburn would not have had interest in the medium state. As it seems now, this drive is quite unusable.

It would be quite astonishing if it worked right now with the same medium loaded as with your above xorriso run. -- Let's break out the big gear and add command -scsi_log "on" to the xorriso run.

You may write it in one line without that "\": ./xorriso/xorriso -scsi_log on -outdev /dev/sr0 -toc 2>&1 | tee -i /tmp/xorriso.log ) This will log the SCSI commands and their replies as they go forth and back between libburn and the drive. Add the emerging file /tmp/xorriso.log as attachment to your next comment. If the attachment is rejected for any reason, send the file to scdbac...@gmx.net as mail body or as attachment.

Hi, > Sense Key 6 "Drive event", ASC 28 ASCQ 81. This SCSI error reply is not listed in SCSI specs SPC or MMC or in the summary of T10 committee https://www.t10.org/lists/asc-num.htm#ASC_28 So the drive's firmware programmers were overly creative. If it was ASCQ 0 or 2, then libburn would tolerate it: 6 28 00 NOT READY TO READY CHANGE, MEDIUM MAY HAVE CHANGED 6 28 02 FORMAT-LAYER MAY HAVE CHANGED but the other ASCQs of ASC 28 were too obscure to me to be tolerable. I now made a GNU xorriso tarball with a libburn which tolerates any Drive event error with ASC 28 so that you can drill deeper into the drive behavior. (I have to think whether this change is good as permanent solution. The list of key 6 errors looks in part fatal like 6 29 00 POWER ON, RESET, OR BUS DEVICE RESET OCCURRED 6 3B 0F END OF MEDIUM REACHED but in part retryable. My program change relies on the hope that all ASC 28 codes are harmless.)

[Bug 1764096] Re: Brasero can't burn DVD because of permissions issue
Hi,
the first message about lack of permissions is common and should be
harmless. The failure happens possibly with the attempt to get 16 MiB
of memory via call mmap(2). But it is not obvious why this only succeeds
if you are superuser.
So this might too be a red herring and the actual reason for wodim to
abort is something that is not reported.
The last messages about "HUP" probably say that wodim closed the pipes
by which it was connected to Brasero. Not necessarily the reason but
rather a consequence of the problem.
The reason for the mmap error message is probably
addr = mmap(0, mmap_sizeparm(size),
PROT_READ|PROT_WRITE, MAP_SHARED, f, 0);
where "f" points to /dev/zero.
(https://sources.debian.org/src/cdrkit/9:1.1.11-3/wodim/fifo.c/#L272)
The man page of mmap says about the error EAGAIN ("Resource temporarily
unavailable"):
EAGAIN The file has been locked, or too much memory has been locked
(see setrlimit(2)).
man 2 setrlimit points to prlimit(1). But running it shows no mmap specific
limiting parameter other than "MEMLOCK", which would only matter if flag
"MAP_LOCKED" was used with the mmap() call.
What do you get from this command:
cat /proc/sys/kernel/shmmax
(Mine says 18446744073692774399. I.e. no real limit.)
What permission do you see with
ls -ld /dev/shm
As a workaround for non-superusers you could switch in Brasero from
the wodim plugin to the libburn plugin. It is supposed to use a slightly
different mmap() call when allocating its fifo buffer.
Have a nice day :)
Thomas

[Bug 1758949] Re: brasero exited on a libisofs error
Hi, regrettably there is no debugging facility in libisofs which one could enable without modifying Brasero. Further the Joliet mangler of libisofs does not produce messages even if i enable DEBUG verbosity when it runs underneath xorriso. The problem with libisofs is only that it does not accept two directories with the same name. The name "CVS pharmacy ... Refil2" was obviously invented by Brasero. It should just not submit it twice. Whatever, the essential question is whether you need the "windows compatibility". What do you see if you put a DVD which was made without that compatibility into a MS-Windows machine ? Are names to see which have uppercase and lowercase characters ? Are filenames longer than 30 characters to see ? If the file names are all uppercase or all lowercase and the long ones are truncated to at most 30 characters, then Brasero does not produce Joliet in this mode. In this case a coarse workaround would be temporarily rename the long names on hard disk and to let Brasero create "windows compatibility". Just don't let it see any file name longer than 64 characters. Elsewise you could try a different burn program. Xfburn, K3b, xorriso- tcltk, ...

[Bug 656297] Re: Brasero always burns CD/DVD at max speed (speed option is ignored)
Hi, since the problem will soon be old enough to go to school, i propose to fix a bug in the libburn plugin of Brasero which is to see at https://git.gnome.org/browse/brasero/tree/plugins/libburnia/burn-libburn.c#n558 This line obviously gets a number out of brasero's state: brasero_job_get_rate (BRASERO_JOB (self), rate); This line hands over the number to libburn as read speed, and orders maximum write speed by value 0: burn_drive_set_speed (priv-ctx-drive, rate, 0); It should obviously be burn_drive_set_speed (priv-ctx-drive, 0, rate); Quoting my predecessors and myself from http://libburnia-project.org/browser/libburn/trunk/libburn/libburn.h /** Sets drive read and write speed Note: k is 1000, not 1024. 1xCD = 176.4 k/s, 1xDVD = 1385 k/s.

[Bug 53962] Re: Nautilus-cd-burner and Brasero are unable to blank DVD-RW
Hi, i noticed that the properties of DVD-RW are misrepresented in some of the posts. DVD-RW can assume two states: sequential and overwritable. The sequential state behaves much like CD-R or DVD-R. The medium has an own table-of-content where it records the track boundaries of one or more burn sessions. DVD-RW in sequential state have to be blanked before they can be re-used from scratch. There are two blanking strategies: fast and full. Fast blanking of DVD-RW causes the medium to be unable of the incremental write type. Only a single track and session can be written in DAO mode. Full blanking lasts as long as writing full DVD of data. It has the benefit, though, to bring the medium into the same state as a virgin DVD-R, which can accept more than one burn session and does not necessarily need to know the size of the session in advance. In the overwritable state, a DVD-RW resembles DVD+RW or DVD-RAM. It has no own table-of-content, and only one track which can be read and written in random access mode with 32 KiB granularity. Overwritable DVD-RW do not need blanking for being re-used from scratch. One may write 64 KiB of zeros to their start in order to invalidate an existing ISO 9660 filesystem, which would cause programs like growisofs or xorriso to append the new data rather than to start writing a completely new ISO 9660 filesystem. DVD-RW are sold in blank sequential state. One may bring a sequential DVD-RW into overwritable state by e.g: dvd+rw-format -force /dev/... One may bring an overwritable DVD-RW or a non-blank sequential DVD-RW into blank sequential state by e.g.: dvd+rw-format -blank=full /dev/... Only capable of DAO writing is the result of dvd+rw-format -blank=fast /dev/... It depends on the state of the medium and on deliberate decisions of the burn frontend program or its user, whether a DVD-RW gets blanked or formatted. With DVD+RW (which have sneaked into this bug report too) there is no decision to be done by the frontend. The backend must know about the peculiarities of DVD+RW background formatting and issue the necessary FORMAT commands if needed. This is the reason why burn programs on DVD+RW sometimes report formatting for a few seconds before they start to write.

[Bug 656297] Re: Brasero always burns CD/DVD at max speed (speed option is ignored)
Hi, i am the developer of libburn, which would probably be in charge for burning underneath Brasero in younger Ubuntu versions. (One can learn from Brasero logs, whether libburn is used as burn backend. Search for Libburn.) There was a bug when the application asked for minimum speed and the firmware of the burner drive incorrectly answered to the SCSI command that inquires the number of offered speed values. That bug is fixed in libburn-1.2.8. I cannot say whether Brasero did ask libburn for minimum speed rather than for a particular speed value. If it did, then the libburn bug would explain the use of maximum speed. But given the original report, that Brasero offered speed 10 for CD-RW with label 1-4x and that the user has chosen 4, i doubt that Brasero triggered the libburn bug. Possibly in 2010 it still used wodim a burn backend for CDs and growisofs for DVDs. In case the bug still persists, i offer my help with investigating Brasero's doings. I am not a user of Brasero myself and my Debian 6 test machine has quite an old version installed. (It is not easy to upgrade Brasero without upgrading the operating system.) I would need a tester who has a much newer version of Brasero. Further we would have to find a publicly readable repository with the source code of that Brasero version. Advise from Ubuntu experts would be welcome in this case. The youngest post of 2013-01-20 by paolode does not look like a speed problem: doesn't burn correctly dvds (it is like it enters in an infinite cycle; If libburn is involved as backend, then i would propose to do experiments with my own command line burn applications cdrskin or xorriso which can report the commands and replies of the SCSI dialog between libburn and burner drive. Both are offered by Ubuntu using the same libburn version as Brasero. If newer versions are needed for the test, then it should make few problems to compile them without disturbing the installed dynamic libburn. (Installing libburn.so from source will probably need an Ubuntu expert.) If libburn is ok - which i assume - then one would again have to inspect the source code of Brasero for the way how it uses libburn. Possibly one will have to insert the libburn call which enables the SCSI log. This will require recompilation of Brasero which might become an adventure on its own.

[Bug 780117] Re: Brasero finishes without error but unusable media ...
Hi, As source I used the downloaded ISO of PartedMagic from 2012_11_30. I simply opened this with Brasero to start burning on a DVD-RW, which first had to be erased. The bug that was fixed here did not affect burning of prepared ISO images, but only composition of ISO images from hard disk files and burning them to media without storing the images ntermediately on hard disk. So your problem is probably something different. After some time I saw 100% complete and something like finalizing the media and I continuously recognized mechanical movements from the readers head. Unformatted DVD-RW get filled up to at least one full GB when they get closed. The image pmagic_2012_11_30.iso has only 274 MB. But 5 to 10 minutes for padding 750 MB would mean only 1x write speed. Then shortly I saw something with successful, but I was unsure, if it was caused by my click or if it had happened anyway. If the drive's activity was still about closing the medium then you would have few chance to interrupt it. Only power-off would do. But if Brasero was attempting to read an unreadable medium, then it might have been your Abort which ended the torture. I'm wondering why Brasero doesn't have a After burning check the content option. I would not be astonished if the strange behavior happened in the course of a verification attempt. To my knowledge it would use readcd. (I am not a regular Brasero user.) --- What happens if you use one of my programs for burning the image ? They are based on libburn like Brasero is by default, but elsewise they do not share code with Brasero. Under the assumption that your burner has the address /dev/sr0 and that a DVD-RW is inserted: xorriso -as cdrecord -v dev=/dev/sr0 blank=deformat_quickest \ -eject pmagic_2012_11_30.iso On a 4x DVD-RW, extra fast blanking lasts about 30 seconds. Writing then shows about 30 seconds of zero progress. Then i get progress messages about 4x write speed. After about 50 further seconds i get a long time of messages xorriso : UPDATE : 274 of 274 MB written (fifo 0%) [buf 99%] 0.0x. with steady burn noise. No head movements to hear. The burn run ends after a total of 264 seconds. A checkread based on the medium's block checksums (DVD ECC) can be done by: xorriso -indev /dev/sr0 -check_media -- -eject all should yield Media current: DVD-RW sequential recording Media status : is written , is closed Boot record : El Torito , ISOLINUX isohybrid MBR pointing to boot image Media summary: 1 session, 140438 data blocks, 274m data, 0 free Volume id: 'Parted Magic' xorriso : UPDATE : 32 blocks read in 5 seconds , 0.0xD xorriso : UPDATE : 1792 blocks read in 6 seconds , 2.6xD ... xorriso : UPDATE : 140438 blocks read in 96 seconds = 2.2xD Hope for no messages like this libburn : SORRY : SCSI error on read_10(16064,32): [3 11 05] Medium error. L-EC uncorrectable error. If they come frequently and progress is slow, then abort by Ctrl+C. libburn gets such messages from the drive if the ECC redundancy does not suffice to obtain a credible data block. A readable medium should yield at the end: Media checks :lba , size , quality Media region : 0 , 140438 , + good I could burn successfully with Windows 7 right after. Was this with the same DVD-RW medium and the same burner ? Well, i just made two tests with above command. The first one really yielded above SCSI error. In the second write-and-check test, no read errors occured. DVD-RW are somewhat adventurous media. I prefer to format them: xorriso -outdev /dev/sr0 -format as_needed -eject all and to use no blank=deformat_quickest when writing to them. As its name says, that option would deformat the medium.

[Bug 780117] Re: Brasero finishes without error but unusable media [on-the-fly mode] (Ubuntu 11.04 -12.04)
Hi, some technical comments to Nico Zanferrari's notes: (I always use a fresh standard live 32 bit USB key with the same DVD-RW) [...] - the unreadable coasters produced from other Ubuntu versions are seen as blank disk from standard brasero 12.10, and can be easily blanked with it. This is different from old versions of brasero that does not recognise it at all as a DVD medium. If the DVD-RW was recorded with write type DAO and suffered the found bug, then it might afterwards bear an unclosed session, because the pre-announced amount of data was not sent to the drive. libburn qualifies such a medium as unsuitable but also offers the opportunity to make it pretend being closed, so that it can be blanked. (Current Brasero git does not bear the necessary call burn_disc_pretend_full(), though.) So it is not sure that this problem is caused by the bug of october 2010. Backporting the fix would be helpful to clarify this. - the bug (don't ask me why) is quite different on 12.10. Here sometimes you can have a readable DVD, but never on the first recording! It seems that it's somehow and sometimes able to record a second recording session on what it thinks it's a blank disk. Theoretically two half sessions of the same size could fill the pre-announced size of the DAO session. But it is hardly possible that the result bears proper directories or file content. The first block of each pair of 2 KB blocks was not written. Any directory, that occupies more than one block, would become damaged. Any data file that has more than one block would not match its original on disk. Again, backporting the fix and testing the effect would bring more insight. If it turns out that there was another bug which is gone in the current git version of Brasero, then it would be worthwhile to identify the changeset which solved that problem.

Did you eject and re-load the CDs which were burned with Brasero, before you tried to read them ? The Linux block device driver does not necessarily know that the SG_IO driver wrote new data to the CD. So it can be that only parts of the new data get visible and old cached data stay visible, until you eject. Re-loading the medium then forces the block device driver to re-assess the medium content.

[Bug 780117] Re: Brasero finishes without error but unusable media [on-the-fly mode] (Ubuntu 11.04 -12.04)
Hi, i am the upstream programmer of libisofs and libburn but not directly involved in Brasero. Andrea Amoroso wrote in #63: still the mp3 cds I burnt are full of the mp3 i chose, with some of them unreadable and others readable but with many lags It is not clear to me whether libisofs was involved with the Brasero run. Did that PPA disable libisofs ? Does burning MP3 create audio CDs for old CD players ? (In that case libisofs would hardly be involved.) Whatever, most likely this report is not about the 50 percent problem, which started bug/780117. It seems rather to be the other bug class, where Brasero finishes without complaint and the medium is unreadable. See also http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=617409 This seems to happen mostly with CDs, not with DVD. As with the Debian bug report, i would rather expect a problem between drive and medium and possibly the write type SAO (in contrast to TAO). If only there was not the statement in bug/780117 that images which were stored on hard disk can later be burned to CD successfully. (Is this really true in the case of comment #63 ?) The 50 percent bug seems to be much rarer than the problem with unreadable CDs after an appearingly successful burn run. It might be that only this one can be avoided by intermediately storing the image on hard disk. Andrea Amoroso wrote in #63: I tried also with Xfburn, no problem with the burning process, but after that I can't even mount the cd, because the device seems empty.. k3b gives an error starting the burning process.. It would be interesting to see the error log of such a failed K3B run. K3B prefers to use mkisofs resp. genisoimage and cdrecord resp. wodim, whereas xfburn uses libisofs and libburn.
