Writing to DVD-RW, DVD+R problems

Hello,

1. I write data to non empty DVD-RW with OCX IDevice.TrackAtOnceFromFileSystemHandle() method. Burning is done sucessfuly, but after it i can read from disc only last written data.

I try to import data by executing IDevice.ImportTrack(jolietImage, true, discInfo.TrackNumber - 1), but it takes no effect. [(discInfo.TrackNumber - 1) equals 0, because DWD-RW disc has 1 track always]

What should i do to save previous disc data?

2. I write data to DVD+R with iDevice.TrackAtOnceFromFileSystemHandle() method(previous track imported in case IDiscInfo.Track number more than 1). Burning completed, than disk ejected and loaded agian. But i can't read any data from disc. It looks like empty disc. Only after second disc ejecting and loading i can read data from disc.
Is it problem of my burning device?
(I have Optiarc DVD RW AD-7173A)

Thanks You,
Alexey

Hi Alexey,

You are right DVD-RW media type have one data track, but begin tracks numerate from 1.

For import last track try to use code something like that:

Code:

//
// Import track 
//            
if(DiscInfo.TrackNumber > 0)             
{                 
   Device.ImportTrack(
                                 JolietImage, 
                                 true,
                                 (ushort)(DiscInfo.TrackNumber)
                                );   
}

//
//Adding new files in to joliet tree
//   
//...

//
//Build image
//
JolietImage.Build((uint)DiscInfo.NextWritableAddress, "Test", "");
