How to Enumerate Serial Number of a Storage Device in File System Driver

NTFSD
1

I have created a File system driver to allow or block the external storage devices in windows. For allowing a particular device I need to find out the Serial Number. I am using PSTORAGE_DEVICE_DESCRIPTOR to find out Serial Number but it will not work for all devices(eg: some devices shows the serial number as a special character). Is there any other possible way to find the Serial number in File system driver

The following are the code used for enumerating the serial number

char szBuff [1024];
STORAGE_PROPERTY_QUERY Query;
//STORAGE_DEVICE_DESCRIPTOR Buffer[4];
NTSTATUS Status = STATUS_SUCCESS;

PSTORAGE_DEVICE_DESCRIPTOR Descriptor=NULL;
PIRP NewIrp2=NULL;
PIO_STACK_LOCATION  NextIrpStack=NULL;
IO_STATUS_BLOCK IoStatus;
char szSptr[2]={'_','\0'};
SIZE_T szLength	= 0;
Query.PropertyId = StorageDeviceProperty;// first set the query properties 
Query.QueryType = PropertyStandardQuery;

KeInitializeEvent(&WaitEvent_newIrp, NotificationEvent, TRUE);// initialize the waitable event

__try 
{
	memset(szBuff,0,1024);

	NewIrp2=IoBuildDeviceIoControlRequest(IOCTL_STORAGE_QUERY_PROPERTY, StorageStackDeviceObject, 
										   (PVOID)&Query,sizeof(STORAGE_PROPERTY_QUERY),
										   szBuff,1024,  
										   FALSE,&WaitEvent_newIrp,&IoStatus);

	if(NewIrp2==NULL)
	{
		return STATUS_SUCCESS;	
	}
	
	Status = IoCallDriver(StorageStackDeviceObject, NewIrp2);// send this irp to the storage device	

	if (Status == STATUS_PENDING)
	{
		KeWaitForSingleObject(&WaitEvent_newIrp, Executive, KernelMode, FALSE, NULL);
		Status =IoStatus.Status;
	}
}
__finally
{
	//if(NT_SUCCESS(Status))
	if(szBuff!=NULL)
	{
		try
		{
			Descriptor = (PSTORAGE_DEVICE_DESCRIPTOR)szBuff;
			Descriptor->Size = sizeof(szBuff);
			uBusType = Descriptor->BusType; //Get the bus type.
		}
		except(EXCEPTION_EXECUTE_HANDLER) 
		{
			/* Error handling code */
		}
	}
	
     char pszStart[255];	

         if(Descriptor->SerialNumberOffset!=0)

            {
                 memset(pszStart,0,255);
	     RtlStringCopyWorkerA(pszStart,255,((char*)(UINT_PTR)Descriptor+(DWORD32)Descriptor->SerialNumberOffset),255);
                  //pszStart contains the serial number

             }
        

    }

Following is the code block used for enumerating the serial number

   char szBuff [1024];
STORAGE_PROPERTY_QUERY Query;
//STORAGE_DEVICE_DESCRIPTOR Buffer[4];
NTSTATUS Status = STATUS_SUCCESS;
PSTORAGE_DEVICE_DESCRIPTOR Descriptor=NULL;
PIRP NewIrp2=NULL;
PIO_STACK_LOCATION  NextIrpStack=NULL;
IO_STATUS_BLOCK IoStatus;
char szSptr[2]={'_','\0'};
SIZE_T szLength	= 0;
Query.PropertyId = StorageDeviceProperty;// first set the query properties 
Query.QueryType = PropertyStandardQuery;
    KeInitializeEvent(&WaitEvent_newIrp, NotificationEvent, TRUE);// initialize the waitable event
__try 
{
	memset(szBuff,0,1024);

	NewIrp2=IoBuildDeviceIoControlRequest(IOCTL_STORAGE_QUERY_PROPERTY, StorageStackDeviceObject, 
										   (PVOID)&Query,sizeof(STORAGE_PROPERTY_QUERY),
										   szBuff,1024,  
										   FALSE,&WaitEvent_newIrp,&IoStatus);

	if(NewIrp2==NULL)
	{
		return STATUS_SUCCESS;	
	}
	
	Status = IoCallDriver(StorageStackDeviceObject, NewIrp2);// send this irp to the storage device	

	if (Status == STATUS_PENDING)
	{
		KeWaitForSingleObject(&WaitEvent_newIrp, Executive, KernelMode, FALSE, NULL);
		Status =IoStatus.Status;
	}
}
__finally
{
	//if(NT_SUCCESS(Status))
	if(szBuff!=NULL)
	{
		try
		{
			Descriptor = (PSTORAGE_DEVICE_DESCRIPTOR)szBuff;
			Descriptor->Size = sizeof(szBuff);
			uBusType = Descriptor->BusType; //Get the bus type.
		}
		except(EXCEPTION_EXECUTE_HANDLER) 
		{
			/* Error handling code */
		}
	}
	
     char pszStart[255];	

         if(Descriptor->SerialNumberOffset!=0)

            {
                 memset(pszStart,0,255);
	     RtlStringCopyWorkerA(pszStart,255,((char*)(UINT_PTR)Descriptor+(DWORD32)Descriptor->SerialNumberOffset),255);
                  //pszStart contains the serial number

             }
        

    }
