Answer 1

Now that you've added all your code, your error is in this line:

Console.WriteLine("{0}\n{1}\n{2}\n{3}\n{4}\n{5}\n",drivename,drivetype,driveformat,max_space,Available_space);

You have 6 parameters, and only fill 5 of them. Each parameter must have a corresponding value(0-based index for 5 values is 0-4). See String.format and Console.WriteLine in MSDN for more info.

So that line should be:

Console.WriteLine("{0}\n{1}\n{2}\n{3}\n{4}",drivename,drivetype,driveformat,max_space,Available_space);
