Getting a list of logical drives

How can I get the list of logial drives (C#) on a system as well as their capacity and free space?

System.IO.DriveInfo.GetDrives()

foreach (var drive in DriveInfo.GetDrives())
{
    double freeSpace = drive.TotalFreeSpace;
    double totalSpace = drive.TotalSize;
    double percentFree = (freeSpace / totalSpace) * 100;
    float num = (float)percentFree;

    Console.WriteLine("Drive:{0} With {1} % free", drive.Name, num);
    Console.WriteLine("Space Remaining:{0}", drive.AvailableFreeSpace);
    Console.WriteLine("Percent Free Space:{0}", percentFree);
    Console.WriteLine("Space used:{0}", drive.TotalSize);
    Console.WriteLine("Type: {0}", drive.DriveType);
}
