en Delphi7, ¿cómo puedo recuperar el número de serie único del disco duro?

Question

Hola, quiero recuperar el número de serie único de HDD (hardware). Uso algunas funciones pero en Windows Seven o Vista no funcionan correctamente debido a la administración correcta. ¿Es posible recuperarlo sin ejecutar como administrador?

Answer 1

Puede usar WMI (Windows Management Instrumentation) para obtener información relacionada con el hardware de Windows.

Existen dos clases de wmi que exponen una propiedad llamada SerialNumber que almacena the Number allocated by the manufacturer to identify the physical media. Estas clases son Win32_DiskDrive y Win32_PhysicalMedia acceder a la propiedad SerialNumber de estas clases, debes conocer el DeviceId del Disco, que es algo así como //./PHYSICALDRIVE0 . Otra forma es utilizar una clase de asociación que vincule la unidad física con la unidad lógica (C, D, E)

entonces debes encontrar este enlace previo para obtener el número de serie. la secuencia para encontrar esta asociación es así.

Win32_DiskPartition -> Win32_LogicalDiskToPartition -> Win32_DiskDrive

Nota 1 : la propiedad SerialNumber para la clase Win32_DiskDrive no existe en Windows Server 2003, Windows XP, Windows 2000 y Windows NT 4.0, por lo que la forma en que se habla de usar Windows Vista o Windows 7 funcionará bien para usted.

Nota 2 : El código no requiere la ejecución de una cuenta de administrador.

Answer 3

Publicando esto puramente para completar, y posiblemente satisfacer a los fanáticos del hard hardware interesados ​​o que mueren.

No tengo un compilador de Pascal a mi disposición para probar estas rutinas en los sistemas actuales de Windows, pero sí sé que este código funcionaba en la era de DOS. Tal vez todavía funciona desde una ventana de símbolo del sistema.

Código de Pascal:

uses
  Dos, Crt;

type
  SerNoType = record
    case Integer of
      0: (SerNo1, SerNo2: Word);

    FileSys: array[1..8] of Char;
  end;

function HexDigit(N: Byte): Char;
begin
  if N < 10 then
    HexDigit := Chr(Ord(''0'') + N)
  else
    HexDigit := Chr(Ord(''A'') + (N - 10));
end;

function GetVolSerialNo(DriveNo: Byte): String;
var
  ReturnArray: DiskSerNoInfoType;
  Regs: Registers;
begin
  with Regs do
  begin
    AX := $440d;
    BL := DriveNo;
    CH := $08;
    CL := $66;
    DS := Seg(ReturnArray);
    DX := Ofs(ReturnArray);
    Intr($21, Regs);
    if (Flags and FCarry) <> 0 then
      GetVolSerialNo := ''''
    else
      with ReturnArray.VolSerNo do
        GetVolSerialNo :=
          HexDigit(Hi(SerNo2) div 16) + HexDigit(Hi(SerNo2) mod 16) +
          HexDigit(Lo(SerNo2) div 16) + HexDigit(Lo(SerNo2) mod 16) +
          HexDigit(Hi(SerNo1) div 16) + HexDigit(Hi(SerNo1) mod 16) +
          HexDigit(Lo(SerNo1) div 16) + HexDigit(Lo(SerNo1) mod 16);
  end;
end;

procedure PutVolSerialNo(DriveNo: Byte; SerialNo: Longint);

Answer 5

Siguiendo los enlaces en los comentarios de la pregunta publicada por Sertac , encontré esta interesante pregunta de C ++ , donde Fredou respondió con un buen enlace a un ejemplo de proyecto de código que muestra cómo hacerlo en .NET , que a su vez se basó en un enlace al código Borland C ++ y artículo .

¡Lo bueno es que este código C ++ también funciona como usuario no administrador!

Ahora necesitas a alguien que te ayude a traducir este código C ++ a Delphi.

Editar : Encontré una unidad Delphi que hace esto por ti.

Escribí algunos ejemplos de uso:

Editar : las configuraciones de RAID requieren disposiciones especiales.

Por ejemplo, obtuve un sistema RAID con varias matrices RAID 5; solo se muestra el primero, y no muestra los números de serie de la unidad, sino el número de serie de la matriz RAID:

VendorId: AMCC
ProductId: 9550SXU-16ML
ProductRevision: 3.08
SerialNumber: 006508296D6A2A00DE82
SerialNumberInt: 688416000
