Have you tried putting a slash at the end of the drive letter?
mo.SetPropertyValue("DriveLetter",@"H:\");
Call Put() to save changes.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Management;
class Program
{
static void Main(string[] args)
{
ManagementClass mc = new ManagementClass("Win32_Volume");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
if ((uint)mo["DriveType"] == 2)
{
try
{
mo["DriveLetter"] = "Z:";
mo.Put();
}
catch (Exception ex)
{
Console.WriteLine("Error: {0}", ex.Message);
}
}
}
}
}
