Windows XP

Windows 7

Total Commander

The code from C# produces 3805184, which corresponds to issuing total commander and issuing windows xp.

DriveInfo drive = new DriveInfo(driveLetter);
var test = (drive.TotalSize - drive.TotalFreeSpace).ToString();

The question is how to achieve the same number in all systems or get the number from Windows 7?

Is the disc multisession? Probably, xp shows only useful data, and 7 - the volume of all sessions. I could be wrong, there is nothing to check. If so, dig into the IMAPI side: IDiscFormat2Data::get_FreeSectorsOnMedia and IDiscFormat2Data::get_TotalSectorsOnMedia
