Re: Problems mounting DVD-RWs written with growisofs
Now I have to write a little wrapper script for growisofs to add -use-the-force... to the command line generated by the frontend. Did you try whether growisofs does not use DAO automatically if the media is blanked fast ? You cannot reliably ask whether the media was blanked fast. It doesn't mean that you can't try. If given firmware tells difference between minimally and fully blanked media, then it tells you that *every* time, i.e. reliably. In other words it's one-time test for user, then [s]he knows that it works reliably or does blank=fast works only correctly if the medium was written on SAO mode before. I can't second this. To start with there is no such thing as SAO in DVD-R[W] context. SAO is a CD recording mode, which means that unit records session lead-in prior user data. There are only two DVD-RW Sequential recording modes: DAO and Incremental. In latter mode structures describing track structure for given recording are written *after* user data is transferred, so it can't be qualified as SAO. But even if we assume, that it was DAO that was intended to stand above, I can't confirm only. Specification only says that DAO is the only applicable recording mode after fast blanking procedure, and telling from own experience, it's not a problem to perform DAO recording after fast blanking procedure applied to DVD-RW media previously recorded in Incremental or Restricted Overwrite mode. I.e. fast blanking worked in compliance with specification regardless previous recording mode. At least in units I've tested. Or should it have read blank=fast *might* work incorrectly *unless* media was recorded in DAO mode before? Where might refers to few firmwares? In which case can we have an example?

Re: Problems mounting DVD-RWs written with growisofs
Hi, Andy's observations with sequential DVD-RW, fast- and full-blanking, and DAO match my own ones with my elder DVD burners (which both went hardly usable meanwhile due to other reasons). To my big surprise the newer generation of my hardware flatly announces feature 0021h, wheras the old ones did only with fully blanked media. The best remedy known to me is to determine whether the conditions of DAO are given: size predictable and no multi desired. In that case DAO should be chosen automatically. Since xorriso and cdrskin (like growisofs) love multi, i have decided to map blank option fast to full blanking with DVD-RW. Only special blank options like deformat_quickest really do MMC fast blanking. If one needs quickly re-usable DVD-RW, then formatting to Restricted Overwrite is superior anyway. (Provided drive and media are suitable.) Have a nice day :) Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

You check for feature 0x21, Incremental Streaming Writable, being current. If it's not, then DAO is the only applicable mode or in other words media in unit is minimally blanked. As already mentioned, it actually worked with all units I've tried. No, I can't claim that I've tested *awful lot* of them, but either way it's not exactly about belief, but practical experience with quite a few. blank=fast works only correctly if the medium was written on SAO mode before.

Re: Problems mounting DVD-RWs written with growisofs
Record in DAO mode? Yes. But you have to pass
explicit -use-the-force-luke=dao. Try that.
One detail question arises to me:
I remember that -dvd-compat on blank DVD-RW caused DAO
from a bug report about scdbackup which tried to pipe
with -dvd-compat.
I have the feeling that we've discussed this, but anyway. If firmware is
in shape, then DAO is engaged automatically. DAO requires prior
knowledge of recording size. Pipe does not give you this knowledge. This
must be conditions where scdbackup suffered the error...
But now that i look into the code of growisofs-7.1
growisofs.c:
intdvd_compat=0, ...
...
else if (!strcmp(opt,-dvd-compat))
{ if (poor_man0) poor_man = 1;
dvd_compat++;
growisofs_mmc.cpp
{ if (dvd_compat = (profile==0x14?2:256))
{ is_dao = 1,
it seems that DAO is not engaged by a single -dvd-compat
Correct.
but would need two of those options.
It was some intermediate suggestion and is kept for backward
compatibility reasons, so please don't get fixated on this. A.

Re: Problems mounting DVD-RWs written with growisofs
Hi, I got problems mouting DVD-RWs written with growisofs -Z /dev/sr2 . kernel: attempt to access beyond end of device kernel: 0b:02: rw=0, want=328386, limit=316032 Did it carry data when it was loaded into the drive ? (Said 316032 blocks perhaps ?) Try whether the problem vanishes if you eject the tray after writing and load it again. Mounting the problematic dvd-rw in a pure dvd-reader-device in could be mounted correctly but input/output errors like above are reported: kernel: attempt to access beyond end of device kernel: 0b:00: rw=0, want=167498, limit=167232 If this is the same media with the same data as above then the difference in numbers is astounding. This would mean the media is plain ill and makes the drives return different size information or different data blocks. I could offer own ISO reading capabilities and a block-wise media check in program xorriso, if you are interested. Probably it will not make the media usability any better, though. DVD+/-R (DL media also) could allways be burned, mounted an read without errors. Drive media compatibility with DVD is a gamble. Especially with DVD-RW there is often trouble. Try DVD+RW instead, or a different brand of DVD-RW with lower nominal speed (e.g. 2x). Have a nice day :) Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

Re: Problems mounting DVD-RWs written with growisofs
Hi, I see Andy showed up. He knows best what growisofs does. :) But my mail was already written when i noticed. So anyway: Marcus Roeckrath wrote: cdrecord dev=1,2,0 opensource_dvd70.iso and the DVD-RW was burned well, could be mounted and all data could be read without any error. Why does the media contains correct size information after burning with cdrecord but is unusable when burned with growisofs? That was DAO recording while growisofs most probably either used Incremental Streaming or Restricted Overwrite. But I uses a server based burning backend on my eisfair server (webcdwriter/CDWserver) which depens on growisofs. growisofs uses DAO on blank DVD-RW with option -dvd-compat growisofs -dvd-compat -Z ... Blank profile 0014h can be achieved by dvd+rw-format -blank /dev/... or cdrecord dev=/dev/... blank=fast As Joerg stated, the fast-blanked media are not suitable for the other recording mode which allows multiple sessions on one media. But for DAO they are ok. DAO needs to know the data amount in advance. growisofs can obtain this number if the image is ISO 9660 or if the data come from a disk file. It cannot do DAO with non-ISO-9660 from stdin. So you have three options with DVD-RW: - Blank media written in DAO mode. Option -dvd-compat or blanked with -blank=fast. - Blank or appendable media written in Incremental Streaming mode. No option -dvd-compat and media blanked by dvd+rw-format -blank=full /dev/... - Formatted DVD-RW. They do not get blanked but for once formatted by dvd+rw-format -force /dev/... From then on they can be overwritten. growisofs will warn of an eventual valid ISO image on media before overwriting it. If it refuses, use the secret weapon: option -use-the-force-luke I tested DVD-RW with all those modes and by own software. None of them could really convince me to buy any further 4x DVD-RW. On my hardware cdrecord had no better results than others. It just failed at other days. So for short time one could get such an impression. But if DAO works for your hardware, then go for growisofs -dvd-compat resp. for fast blanked media. (If the service in question provides the data with predictable size, that is.)

With growisofs this depends on the formatting state of the media. Profile 0013h DVD-RW restricted overwrite or profile 0014h DVD-RW sequential recording. The dirty trick is applied to 0013h and is a good reason to applaud Andy Polykov. One can carry it even one step further to obtain an emulated Table Of Content on overwriteable media and in disk filesystem objects: TOC layout : Idx , sbsector , Size , Volume Id ISO session : 1 ,32 ,742034s , HOME_2008_11_05_213825 ISO session : 2 ,742080 , 32588s , HOME_2008_11_06_221656 Andy will surely recognize why the start LBA 32 of the first session is essential for that. :) Others may learn from http://libburnia-project.org/browser/libburn/trunk/doc/cookbook.txt ISO 9660 multi-session emulation on overwriteable media ISO 9660 based TOC emulation on overwriteable media Media in state 0014h DVD-RW sequential recording are handled like DVD-R. That's what you call multi-border and what MMC-5 calls Incremental Streaming feature. 32 kB fixed size packets in a track and session oriented model like with CD-R in mode TAO. You can get DAO by option -dvd-compat or by fast-blanked DVD-RW if the drive does not lie about feature 0021h Incremental Streaming. My Samsung tells it is present although it then fails. Shrug.

Re: Problems mounting DVD-RWs written with growisofs
In contrary to cdrecord, growisofs does not implement multi-border support Yes, it does! Virgin and fully blanked DVD-RW media are written in compliant multi-border manner! DVD-R[W] multi-border support was there from day DVD-R[W] support was added to growisofs, along with Restricted Overwrite DVD-RW support. Does this mean you only use the trick for DVD+RW? No. ISO9660 volumes on DVD-RW *Restricted Overwrite* are treated in the same way as on DVD+RW. As well as on DVD-RAM, BD-RE, BD-R formatted for Pseudo-Overwrite. It should be noted that in last case media can be treated as both multi-session[/-border] and expandable single-session. Or rather multi-session capable OSes will mount it as if it was multi-session, while non-multi-session capable OSes will mount first session, yet be able to access files from all the sessions.

Re: Problems mounting DVD-RWs written with growisofs
*ALWAYS* complement problem reports with dvd+rw-mediainfo output for the problem recordings. It's virtually impossible to say something really meaningful without it. Even log output from actual recording is desired might even be required [naturally most of progress indicator can be omitted. 1. Blanked previous used media using cdrecord blank=all dev=1,2,0 For reference, you can do same with 'dvd+rw-format -blank=full /dev/sr2'. 2. Wrote iso image growisofs -Z /dev/sr2=opensource_dvd70.iso Output: Executing 'builtin_dd if=opensource_dvd70.iso of=/dev/sr2 obs=32k seek=0' /dev/sr2: Current Write Speed is 4.1x1352KBps. 7340032/2299527168 ( 0.3%) @1.6x, remaining 20:49 RBU 99.4% UBU 4.8% [...] 2289008640/2299527168 (99.5%) @3.0x, remaining 0:02 RBU 29.7% UBU 19.0% builtin_dd: 1122816*2KB out @ average 2.6x1352KBps /dev/sr2: flushing cache /dev/sr2: updating RMA /dev/sr2: closing session For reference. All these updating RMA and closing session commands are pure firmware domain. In particular there are no parameters reflecting track size passed with these commands. Unit firmware is expected to keep track of last written block, 1122816 as we see in builtin_dd summary, and to write it to RMA, TOC and whatever structures required. Question is does it? That's where mediainfo comes into picture: 3. Mediainfo eis # dvd+rw-mediainfo /dev/sr2 INQUIRY:[PLEXTOR ][DVDR PX-740A ][1.00] GET [CURRENT] CONFIGURATION: Mounted Media: 14h, DVD-RW Sequential Media ID: MCC 01RW4X ...

Try to copy the content of the mounted device to hd failed: Cannot read source file media/dvdwriter2/Autorun.inf Input/Output error (5) Reporting in /var/log/messages: Nov 20 16:47:30 eis kernel: attempt to access beyond end of device Nov 20 16:47:30 eis kernel: 0b:02: rw=0, want=2242880, limit=130528 This is perfectly consistent with value returned to READ CAPACITY rescaled to 1KB. READ CAPACITY is what defines the end of device. As mentioned writing values like last border-out, next writable address, those defining capacity is pure firmware domain. So it appears as if firmware failed miserably to record consistent and meaningful values. Question is how come? I don't know. Pioneer unit worked for me at numerous occasions and it worked for numerous users with other units... On the other hand there were several reports earlier all mentioning last border-out at 2045... Yet I don't have solid clue about this 2045 phenomena... Can it be that it gets screwed up under buffer underruns? I mean as actual average speed was 2.6x, while unit intended to record at 4x, it had to suffer multiple buffer underruns. But how come 2045 at several occasions? Common firmware deficiency? But it was observed with different vendors... Though it doesn't really exclude possibility of common firmware deficiency, because there is a lot of re-badged units out there... Another question is how come cdrecord succeeded? The catch is that by default it's recording in DAO mode, which requires that application sends track size prior recording, and all last border-out, table of contents, capacity structures residing in lead-in are recorded *prior* data. This is unlike multi-border recordings [which is default mode for growisofs when it comes to write-once and virgin or fully-blanked DVD-RW], when data is recorded first and *then* lead-in. Can growisofs do that? Record in DAO mode? Yes. But you have to pass explicit -use-the-force-luke=dao. Try that... Also try -speed=2.

Hi,

One detail question arises to me:
I remember that -dvd-compat on blank DVD-RW caused DAO
from a bug report about scdbackup which tried to pipe
with -dvd-compat.
But now that i look into the code of growisofs-7.1
growisofs.c:
intdvd_compat=0, ...
...
else if (!strcmp(opt,-dvd-compat))
{ if (poor_man0) poor_man = 1;
dvd_compat++;
growisofs_mmc.cpp
{ if (dvd_compat = (profile==0x14?2:256))
{ is_dao = 1,
it seems that DAO is not engaged by a single -dvd-compat
but would need two of those options.
(-use-the-force-luke=dao gains generous 256 points.)
So another variation comes to my mind: Incremental closed.
(Now we have four legal states after first session.
Plus the totally ill one we see on Marcus' media.)
Whatever, if Marco cannot set growisofs options via
the affected frontend, a try with fast-blanked DVD-RW
is nearly the last resort.
A try with formatted DVD-RW would then be the really
very last one. (I am not overly optimistic with that.)
Have a nice day :)
Thomas
