Answer 1

I was looking for the size in GB, so I just improved the code from Superman above with the following changes:

public double GetTotalHDDSize(string driveName)
{
    foreach (DriveInfo drive in DriveInfo.GetDrives())
    {
        if (drive.IsReady && drive.Name == driveName)
        {
            return drive.TotalSize / (1024 * 1024 * 1024);
        }
    }
    return -1;
}
