Hi I want to retrieve HDD unique (hardware) serial number. I use some functions but in Windows Seven or Vista they don't work correctly because of admin right. Is it possible retrieve it without run as Administrator?

Following the links in the question comments Sertac posted, I came across this interesting C++ question, where Fredou answered with a nice link to a codeproject example showing how to do this in .NET, which in turn was based on a link to Borland C++ code and article.

The cool thing is that this C++ code works as a non-administrator user too!

Now you need someone to help you translate this C++ code to Delphi.

Edit: Found a Delphi unit that does this for you.

I wrote some sample use for it:

program DiskDriveSerialConsoleProject;

{$APPTYPE CONSOLE}

uses
  Windows,
  SysUtils,
  hddinfo in 'hddinfo.pas';

const
  // Max number of drives assuming primary/secondary, master/slave topology
  MAX_IDE_DRIVES = 16;

procedure ReadPhysicalDriveInNTWithZeroRights ();
var
  DriveNumber: Byte;
  HDDInfo: THDDInfo;
begin
  HDDInfo := THDDInfo.Create();
  try
    for DriveNumber := 0 to MAX_IDE_DRIVES - 1 do
    try
      HDDInfo.DriveNumber := DriveNumber;
      if HDDInfo.IsInfoAvailable then
      begin
        Writeln('VendorId: ', HDDInfo.VendorId);
        Writeln('ProductId: ', HDDInfo.ProductId);
        Writeln('ProductRevision: ', HDDInfo.ProductRevision);
        Writeln('SerialNumber: ', HDDInfo.SerialNumber);
        Writeln('SerialNumberInt: ', HDDInfo.SerialNumberInt);
        Writeln('SerialNumber

Here is another DiskId32 translation from C++ to Delphi by Victor Derevyanko

project: http://code.google.com/p/dvsrc/

Because the first method (WithZeroRights) doesn't work for me, I wrote another for ReadIdeDriveAsScsiDriveInNT method:

unit HDScsiInfo;

interface

uses
  Windows, SysUtils;

const
  IDENTIFY_BUFFER_SIZE = 512;
  FILE_DEVICE_SCSI = $0000001b;
  IOCTL_SCSI_MINIPORT_IDENTIFY = ((FILE_DEVICE_SCSI shl 16) + $0501);
  IDE_ATA_IDENTIFY = $EC;  //  Returns ID sector for ATA.
  IOCTL_SCSI_MINIPORT = $0004D008;  //  see NTDDSCSI.H for definition

type
  TDiskData = array [0..256-1] of DWORD;
  TDriveInfo = record
    ControllerType: Integer; //0 - primary, 1 - secondary, 2 - Tertiary, 3 - Quaternary
    DriveMS: Integer; //0 - master, 1 - slave
    DriveModelNumber: String;
    DriveSerialNumber: String;
    DriveControllerRevisionNumber: String;
    ControllerBufferSizeOnDrive: Int64;
    DriveType: String; //fixed or removable or unknown
    DriveSizeBytes: Int64;
  end;

  THDScsiInfo = class (TObject)
  private
    FDriveNumber: Byte;
    FFileHandle: Cardinal;
    FInfoAvailable: Boolean;
    FProductRevision: string;
    FSerialNumber: string;
    FControllerType: Integer;
    FDriveMS: Integer;
    FDriveModelNumber: string;
    FControllerBufferSizeOnDrive: Int64;
    FDriveType: string;
    FDriveSizeBytes: Int64;
    procedure ReadInfo;
    procedure SetDriveNumber(const Value: Byte);
    procedure PrintIdeInfo(DiskData: TDiskData);
  public
    constructor Create;
    property DriveNumber: Byte read FDriveNumber write SetDriveNumber;
    property ProductRevision: string read FProductRevision;
    property SerialNumber: string read FSerialNumber;
    property ControllerType: Integer read FControllerType;
    property DriveMS: Integ
