Informations about HDD

I'm trying to get informations about my HDD, and I plan to use
DeviceIoControl, but i don't understand how to use it,:
First of all Function asks me to sign dwIoControlCode (this is
DRIVE_LAYOUT_INFORMATION_EX) and it must be an integer, so how can I found
it as integer.

If anyone have a sample code for this purpose, please sent it to me by
email.


[DllImport("Kernel32.dll", SetLastError = true)]
static extern bool DeviceIoControl(
IntPtr hDevice,
int dwIoControlCode,
IntPtr lpInBuffer,
int nInBufferSize,
IntPtr lpOutBuffer,
int nOutBufferSize,
out int lpBytesReturned,
IntPtr lpOverlapped
);


Thanks a lot

Most (if not all) disk drive info can be obtained using the
System.Management and the WMI classes.
Here's a sample to get you started...

using System;
using System.Management;
// Enum mapped network drives
class App {
public static void Main() {
// Get drive info for first HD drive
ShowHDproperties("Win32_DiskDrive.DeviceId='\\\\.\\PHYSICALDRIVE0'");
}
static void ShowHDproperties(string objectClass) {
ManagementObject hd;
using(hd = new ManagementObject (objectClass))
{
hd.Get();
PropertyDataCollection hdProperties = hd.Properties;
foreach (PropertyData hdProperty in hdProperties ) {
if(hdProperty.Value !=null) // Show only non-null property values
Console.WriteLine("Property = {0}\t Value = {1}",
hdProperty.Name, hdProperty.Value);
}
foreach (ManagementBaseObject b in hd.GetRelated()) {
Console.WriteLine("--------------- {0} -----------------",
b.ClassPath.ToString());
ShowHDassocProperties(b.ToString());
b.Dispose();
}
}
}
static void ShowHDassocProperties(string objectClass) {
ManagementObject hd;
using(hd = new ManagementObject (objectClass))
{
hd.Get();
PropertyDataCollection hdProperties = hd.Properties;
foreach (PropertyData hdProperty in hdProperties ) {
if(hdProperty.Value !=null) // Show only non-null property values
Console.WriteLine("Property = {0}\t Value = {1}",
hdProperty.Name, hdProperty.Value);
}
}
}
}

Add a reference to your project for System.Management
