Get Hard disk serial Number

Question

I want to get hard disk serial number. How I can I do that? I tried with two code but I am not getting

StringCollection propNames = new StringCollection(); ManagementClass driveClass = new ManagementClass("Win32_DiskDrive"); PropertyDataCollection  props = driveClass.Properties; foreach (PropertyData driveProperty in props)  {     propNames.Add(driveProperty.Name); } int idx = 0; ManagementObjectCollection drives = driveClass.GetInstances(); foreach (ManagementObject drv in drives)        {           Label2.Text+=(idx + 1);           foreach (string strProp in propNames)            {             //Label2.Text+=drv[strProp];          Response.Write(strProp + "   =   " + drv[strProp] + "</br>");           }     } 

In this one I am not getting any Unique Serial number.
And Second one is

string drive = "C"; ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"" + drive + ":\""); disk.Get(); Label3.Text = "VolumeSerialNumber="+ disk["VolumeSerialNumber"].ToString(); 

Here I am getting VolumeSerialNumber. But it is not unique one. If I format the hard disk, this will change. How Can I get this?

Hm, looking at your first set of code, I think you have retrieved (maybe?) the hard drive model. The serial # comes from Win32_PhysicalMedia.

Get Hard Drive model

    ManagementObjectSearcher searcher = new     ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");     foreach(ManagementObject wmi_HD in searcher.Get())    {     HardDrive hd = new HardDrive();     hd.Model = wmi_HD["Model"].ToString();     hd.Type  = wmi_HD["InterfaceType"].ToString();      hdCollection.Add(hd);    } 

Get the Serial Number

 searcher = new     ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");     int i = 0;    foreach(ManagementObject wmi_HD in searcher.Get())    {     // get the hard drive from collection     // using index     HardDrive hd = (HardDrive)hdCollection[i];      // get the hardware serial no.     if (wmi_HD["SerialNumber"] == null)      hd.SerialNo = "None";     else      hd.SerialNo = wmi_HD["SerialNumber"].ToString();      ++i;    }
