delphi – in Delphi7, How can I retrieve hard disk unique serial number? – Stack Overflow

Posted by jpluimers on 2019/01/30

From long time ago, but since I needed it in Delphi 2007 again: [WayBack] delphi – in Delphi7, How can I retrieve hard disk unique serial number? – Stack Overflow:

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.

EditFound 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('SerialNumberText: ', HDDInfo.SerialNumberText);
      end;
    except
      on E: Exception do
        Writeln(Format('DriveNumber %d, %s: %s', [DriveNumber, E.ClassName, E.Message]));
    end;
  finally
    HDDInfo.Free;
  end;
end;

begin
  ReadPhysicalDriveInNTWithZeroRights;
  Write('Press <Enter>');
  Readln;
end.

EditRAID configurations require special provisions.

For instance, I got a RAID system with multiple RAID 5 array; only the first one displays, and it does not show the drive serial numbers, but the serial number of the RAID array:

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