Comment 5 for bug 451350

I get the same symptom and fiddling around with cdrecord I find that the options used for the burn are not compatible with the supported modes of the drive. The same error is reported in his attached brasero-session.log

> Excerpt from mine:
 Supported modes: TAO PACKET SAO SAO/R96P SAO/R96R
> Excerpt from attached brasero-session.log
 Supported modes: TAO PACKET SAO

Taking the command reported in the attached brasero-session.log
$ wodim -v dev=/dev/sr0 speed=24 driveropts=burnfree -raw96r fs=16m -clone /home/user/brasero
...
 Supported modes: TAO PACKET SAO SAO/R96P SAO/R96R
...
 wodim: Drive does not support RAW recording.
 wodim: Illegal write mode for this drive.

Removing -clone and -raw96r successfully writes _something_ to the disk, but its not a valid disk once its done. The -clone mode used on read requires -raw96r on write and its unsupported by these drives.

Adding in -sao (as suggested by my drives capabilities: SAO/R96R) returns:
 wodim: SAO RAW writing not yet implemented.

So possibilities occur (to unknowledgeable me):
1. wodim doesn't recognise that the drives support RAW any more (and did in Jaunty)
2. brasero has changed the way it reads and writes whole disks and this mode (-clone) isn't compatible with drives that don't support RAW (and the old way was)

I'll try to boot up in jaunty and see if wodim reports the same sets of supported modes

Some extra detail:
