Any systematic problem with CD SAO would be restricted
to a very small set of drives. I use up a drive per
year and never got one that could not do SAO and TAO.
Yamaha, Lite-ON, LG, NEC, Samsung - all ok until they
did their due share of work and some day begin to
produce more and more failures.

If raw mode prevents hald from disturbing a
burn run then this is an undocumented feature.

It may be as well an urban legend like the
one behind padsize=300k and TAO.

So no hald is involved here anyway.
Arresting the usual suspect did not help.


Known is that there was a failure with cdrecord,
a success with cdrecord -raw96r, and a success
with cdrskin (SAO). There also seem to be problems
with DVD. Helmut reports of a long idle time
before writing begins. (Exact media type unknown)

To Helmut: any new insight ?
Can you give us an overview of success and failure ?
(With media type and with commands that were used)


Have a nice day :)
