How can I determine the capacity in bytes of:

1. A blank Disc?

2. A Rewriteable Disc that will be erased and reused?


I need to beable to create an ISO/Joliet image file that will fit on the disc, so what is the best method of doing this?

Thanks

Also, It appears that the default Block Size is 2KB, is this correct?

If so, then I can calculate the capactiy of a blank disc from:

LARGE_INTEGER Size;
Size.QuadPart = l__TRACK_INFORMATION.m__LONG__FreeLBs * 2048;


For a rewriteable, the size would be:

( m__LONG__FreeLBs + m__LONG__NextWritableAddress ) * 2048;


Does this look correct?

Thanks

You need to get invisible track size (0xFF) in logical block and multiply it to 2048 bytes for data track or 2352 bytes for audio track.
