I develop an activation for a system. to generate request code, I used HDD ID, Bios ID and Processor ID. I used following code to get hard disk ID.
private string getHardDiskID()
{
string hddID = null;
ManagementClass mc = new ManagementClass("Win32_LogicalDisk");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject strt in moc)
{
hddID += Convert.ToString(strt["VolumeSerialNumber"]);
}
return hddID.Trim().ToString();
}
But if I plug a removable disk, That ID value is changed. How to get the UNIQUE Serial Number of the hard drive...? Thanks in advance..
You can try from this source :
As said in the source, a better solution is to get the Hard Drive Serial Number given by the Manufacturer. This value won't change even if you format your Hard Drive.
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;
}
Check below code to get HDD Serial
ManagementObjectSearcher objSearcher = new
ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
objSearcher = new
ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
int i = 0;
foreach(ManagementObject wmi_HD in objSearcher.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;
}
Also You can type "wbemtest" in windows run. WBEMTEST is tool which helps in running WQL queries.
ManagementObjectSearcher searcher;
searcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
string serial_number="";
foreach (ManagementObject wmi_HD in searcher.Get())
{
serial_number = wmi_HD["SerialNumber"].ToString();
}
MessageBox.Show(serial_number);
