Re: growisofs won't write double layer DVDs
Christian, I feel that I have to apologize for Joerg's rude behavior. Cdrecord will tell the drive to do laser power calibration cdrecord does not do that to DVD+ media. Wrong: cdrecord of course does a power calibration for DVD+ LOCAL BOOL ... Interesting that you seem to have time to write this but to not like to support mkisofs. If you really have problems with mkisofs, please make reports in a way that allows to fix them. Joerg, if you want to make personal remark, do it in proper context, or at least have decency to omit originator from explicit Cc: list. It's indeed nothing but rude to flip conversation like this, as if person just ceased to exist. A. -- To UNSUBSCRIBE, email to cdwrite-requ...@other.debian.org with a subject of "unsubscribe".

Re: growisofs won't write double layer DVDs
I recommend you to use cdrecord instead of growisofs.
Cdrecord will tell the drive to do laser power calibration
cdrecord does not do that to DVD+ media.
Wrong: cdrecord of course does a power calibration for DVD+
I thought it bypassed that for DVD+,
It is.
I saw it in the code and can't find
it again. It looked as if a text which fails on DVD+ went around that logic.
Does cdr_opc get set somewhere I'm missing? That could explain why some
media I have don't work well with one burner and cdrecord.
It should be noted that explicit *host-initiated* OPC procedure is *not*
defined for single-layer DVD+ media. Meaning that if you refer to single
layer media, then there hardly is cure (at least not in pure MMC terms).
As it turns out it, host-initiated OPC, is defined for double layer
though and it might make difference...
Christian [and Bill], if you have energy and media to spare, could you
test following:
- download dvd+rw-tools source and unpack;
- copy attached opc.cpp to dvd+rw-tools source catalog;
- change directory to dvd+rw-tools source catalog;
- compile it with 'g++ opc.cpp -o opc';
- load media;
- execute './opc /dev/dvd';
- then *without reloading the media* attempt growisofs recording;
It might be interesting to have a look at verbose dvd+rw-mediainfo
output before and after opc. In other words also execute dvd+rw-medianfo
/dev/dvd -v before and after opc (all *without reloading the media*),
compare them and send them [*if* they are different]. A.

LOCAL BOOL
do_opc(scgp, dp, flags)
SCSI*scgp;
cdr_t *dp;
UInt32_t flags;
{
if ((flags & F_DUMMY) == 0 && dp->cdr_opc) {
if (debug || lverbose) {

So it's up to [non-NULL!] dp->cdr_opc. And what's dp->cdr_opc for DVD+
media?
grep OPC drv_dvdplus.c

Re: growisofs won't write double layer DVDs
I'm trying to write double layer DVDs on my TS-L632C DVD burner. It has always handled single layer DVDs fine and this is the first time I have a problem. What I get is this... Executing 'mkisofs -dvd-video -V DVD /home/abc/dvd | builtin_dd of=/dev/sr0 obs=32k seek=0' Setting input-charset to 'UTF-8' from locale. 0.17% done, estimate finish Thu Jan 1 13:43:04 2009 0.35% done, estimate finish Thu Jan 1 13:43:04 2009 0.52% done, estimate finish Thu Jan 1 13:43:04 2009 /dev/sr0: splitting layers at 1437552 blocks :-[ SEND DVD+R DOUBLE LAYER RECORDING INFORMATION failed with SK=3h/POWER CALIBRATION AREA ERROR]: Input/output error growisofs still does not write completely readable error messages :-( This is an opinion. The fact is that whether or not and when power calibration is performed is left to firmware discretion. "Not" refers to fact that firmware might choose pre-defined profile. "And when" on the other hand varies from firmware to firmware, some firmware start the calibration procedure at a WRITE command, others at SEND DVD STRUCTURE with DVD+R DL layer break position. As result power calibration errors get accounted to either of these commands. Christian, as for error interpretation and advice, see Thomas' post. I recommend you to use cdrecord instead of growisofs. Cdrecord will tell the drive to do laser power calibration cdrecord does not do that to DVD+ media.

Cdrecord will tell the drive to do laser power calibration and it will print you a completely human readable error message in case it still fails. If cdrecord fails with the same problem, then your drive does not like the medium.
