[Debburn-devel] Strange Problem with DVD Writing

Hi,

This is indeed interesting and worth a discussion.
I'm a bystander here, not a member of cdrkit project.

A first curious question:
Are there known methods to reset the drive
so that it burns DVD again ?
Does rebooting help ?
Unloading and reloading of kernel modules ?

Yep. The drive was ordered to perform own OPC,
i.e. to adjust its physical calibration to the
condition of the media.

Is there a special reason why you use up a DVD-R for
352 kilobytes of data ?

I doubt that any announced track size can spoil OPC.
But i would also have doubted that burning a CD
can spoil subsequent DVD burning.

This error 0,00,02 is not listed in MMC-5.
I wonder where the textual representation was found:
"(end-of-partition/medium detected)".

Whatever, it comes from command SEND OPC which does
not offer much variations. There is not much hope
that the drive will skip OPC if this command is not
sent. Drive firmware loves to do OPC.

So other burn programs will hardly be able to avoid OPC
- if that is desirable at all.

A "Ricoh Vendor Page" is not listed in MMC-5.
Maybe its inquiry confuses the drive.

This could be a reason to try other DVD burn programs:
- growisofs out of
    http://fy.chalmers.se/~appro/linux/DVD+RW/tools/dvd+rw-tools-7.1.tar.gz
- cdrskin out of
    http://scdbackup.sourceforge.net/cdrskin-0.4.4.pl00.tar.gz
  (this is my own burn program)

growisofs has the longer experience with DVD,
but is not compatible with cdrecord options.
You run would rather look like:
  growisofs -Z /dev/dvd -R temp3/
which includes "genisoimage -print-size" and
"genisoimage -R temp3/".

cdrskin could perform your wodim/cdrecord 
option list:
  genisoimage -R temp3/ | cdrskin -v -speed=4 dev=/dev/dvd tsize=176s
where the "tsize=176s" may be omitted to get a different
write mode. That mode is like -tao for CD, i.e. it does
not get the track size in advance.
Try it, just in case that 176s is a problem despite my opinion.


Have a nice day :)
