Hi,

when trying to burn a multi session disc, I get the following error when trying to continue a previous disc:
CStarBurn_CdvdBurnerGrabber::SessionAtOnceEx(): NWA not valid, 38400 instead of ( -150 )

I'm using the UDF databurner, STARBURN_WRITE_MODE_SAO, STARBURN_UDF_VERSION_1_02, CD-R.

For details, see attached log file.

So, this error means that "You can burn SAO disc on the empty media only!"

Regards,

Then how can I burn multi session discs, if not using SAO?

Hello,

Use TAO mode ( the NextSessionAllowed property should be set to TRUE )!

Regards,

Dmitry

Does this apply to all media types (CD, DVD, ...)?

CD only. You cannot burn DVD and BD in RAW mode. Neither with StarBurn nor with anything on Earth.

So you cannot create multisession DVDs and Blu-Ray discs? Or what do you mean with RAW?

You *can* create multisession DVDs and BDs, you cannot burn them using block size different from 2048 byte.

I don't think I understand you. Could you try speaking in terms of your StarBurnX API instead of technical block size, raw mode whatever terms?

I am told to use TAO for multi session discs (which I understand), but you told me this is not possible for Blu-Ray and DVD. So what else do I use?

Yes use TAO for multisession BDs and DVDs as they don't support SAO or DAO.
