#1 Burning Software

Hello Dima Sir,
I am using StarBurnX, DataBurner class to burn data on disc. [Developing in VB.NET 2005 & Referring sample provided with SDK]
My Requirement: I want burn data on R/W disc. If the disc is not empty then call disc erasing from code, without giving any type of error or without ejecting drive & continue erasing followed by burning.
What should I do to fulfill my requirement?

I have tried following things in a sample created by using the sample provided SDK and facing a problem discussed in step 6.
Steps followed:
1) After adding 500 MB data, I want to burn data on inserted Moserbear R/W DVD. This DVD is already having some 200 MB data on it.
2) For burning it, I am checking the disc type & disc status.
3) If it is R/W DVD with status Incomplete then I am erasing [in quick mode(for reducing time required for burning)] it from my code.
4) After completing erasing, I have to call DiscInfo.Refresh() to refresh the disc information fetched by application. [With condition: I don't want to eject the drive.]
5) Now after this step, I am calling DataBurner.Burn(...).
Problem: 6) The problem is some times the call in step 4 for Refreshing disc information fails & in this case in above step 5 in DataBurner.Burn Disc has no free space this error comes up.

Am I doing anything wrong? Will you kindly tell me how to fulfill my requirement.

Eject is required. Doing software reset works on some drives but fails on the others. So you cannot do what you want to do. Physically.
