[Debburn-devel] LG CH08LS10 not burning CDs

Hi,

Does he have the same burner and firmware ?

We have a report in this thread that revoking a
firmware upgrade revoked the problem too.
(Was it by you ? The thread gets longer and longer.)

It would be so easy to make the firmware safe.
It should just reject the incomming requests
which would lead to burn aborts, rather than
switching out of burn mode and refusing on the
next write command.

Yeah. That's one of the well known culprits.
On my system it spoils about 1 burn out of five.
Easy to spot and easy to kill selectively for
each drive.

If it moves the lens to block 0 every two
seconds then this might slow down the DVD burn
more and more as the write position moves out.
It has the full potential to spoil CD-R[W] runs.

It is one of the known error message caused by
drive molesters. Even more strange is
  2 30 06 CANNOT FORMAT MEDIUM  INCOMPATIBLE MEDIUM
which one can get too.
There seem to be several occasions for the burn
failure which trigger different errors.
There is no clear rule when to issue which one.
So expect different errors on different drives.

Are the dmesg messages gone when hal-addon-storage
is gone ?
Is it really gone ?


Have a nice day :)
