#1 Burning Software

Hello,

How to verify the written data using StarBurn SDK? I want to verify the disc that has been really written the right data after finish burning. But when i use the method 'StarBurn_CdvdBurnerGrabber_GetTOCInformation' to read the TOC information before eject the disc, it alway return an erron message, but it is okay when after eject the disc. Thanks you very much.

Thanks

Until you don't eject the disc drive keeps "cached" information about medium. That's why you just need to do "eject-load" sequence (either programmatically - not recommended as some morbid devices like to fail load commands) or asking user assitance with "please load the disc after eject" message box. After the disc is loaded please use TOC information to get disc layout and just use StarBurn_CdvdBurnerGrabber_ReadRange(...) or _Read10(...) code to get "cooked' data to compare with original image you're recording (true or virtual "in-memory" one - just don't forget to call ->SeekToBegin(...) on it before verification as marker would be on the end position after recording). That's all...

Thank you very much

Hi Anton,

Can you please provide more detail on how to do it ? CdvdBurnerGrabber_ReadRange(...) and _Read10(...) are not documented in the help file. A sample would help

Thanks,
Chris

Threre's a sample for GrabRange. And first I'd like to know how you're expecting to do comparation process - grab track content and compare it to the file on the disk (using whole image CRC verification or whatever) or compare readen track content with in-memory image content?

Hi Anton,

I need the fastest way to do the verification, so I am guessing comparing to in-memory image content would be fastest ?

I think - yes. It would be the fastest way.
