如何获得硬盘序列号？

procedure TForm1.Button1Click(Sender: TObject);
var SerialNum : pdword; a, b : dword; Buffer : array [0..255] of char;
begin
  if GetVolumeInformation('c:\', Buffer, SizeOf(Buffer), SerialNum, a, b, nil, 0) then Label1.Caption := IntToStr(SerialNum^); end;

忘了，不过dir就行，记得msdn里有篇如何改序列号的（曾经想过要改实验室90台机的vol c，结果ghost了事），用汇编的

这是取硬盘ID的，我的2K Server下可以工作

不用那么麻烦吧，这样绝对没问题（试过100块IBM T32的硬盘）：

function GetIDESN: Cardinal;
Var
cSN:Cardinal;
MaxNameLength:Cardinal;
FSFlag:Cardinal;
begin
GetVolumeInformation('C:\',nil,0,@cSN,MaxNameLength,FSFlag,nil,0);
Result:=cSN;
end;上面 goodloop(小志)的程序好像指针（SerialNum : pdword）没有分配空间，不知道会不会出问题。

获得的不是序列号，而是卷标

用VC编写的DLL，可以获得硬盘的型号、序列号以及计算机 ID，带Delphi的源程序，在Win2K下通过，但是没有在Win9X下试过，感兴趣的朋友可以在Win9X 下试一下，或者编写一个VB的范例。
函数以及定义：
function ReadPhysicalDrive(driveID:integer;buffer:Pointer;bufLen:integer):integer; stdcall; external 'DiskID.dll' name 'ReadPhysicalDriveInNT';
获得WinNT下的硬盘型号以及序列号。参数driveID为硬盘的位置，IDE1上的主盘为0，类推到IDE2上的从盘的driveID为3。
function ReadPhysicalDrive9X(driveID:integer;buffer:Pointer;bufLen:integer):integer; stdcall; external 'DiskID.dll' name 'ReadDrivePortsInWin9X';
获得Win9X下的硬盘型号以及序列号。参数同上
function getHardDriveComputerID:int64; stdcall; external 'DiskID.dll' name 'getHardDriveComputerID';
获得计算机的ID http://www.applevb.com/lib/diskio.rar

你试试这个吧！取Ide硬盘序列号函数

用取序列号作为程序加密并不是完全可行的。有的IDE硬盘并不具有序列号，而SCSI硬盘更是没有序列号一说，我试过三块SCSI硬盘，都不能取得序列号，不过，如果软件是装在某一台固定的机器上的话，用这个方法还是很不错的。

//==============================================================================

function GetHardDiskSerial(Drive: string): string;
var VolumeSerialNumber: DWORD;
    MaximumComponentLength: DWORD;
    FileSystemFlags: DWORD;

  if Drive[Length(Drive)]=':' then Drive := Drive + '\';
  GetVolumeInformation(PChar(Drive), nil, 0, @VolumeSerialNumber, MaximumComponentLength, FileSystemFlags, nil, 0);
  Result := IntToHex(HiWord(VolumeSerialNumber), 4) + '-' + IntToHex(LoWord(VolumeSerialNumber), 4);
end;

要获取win98系统上的硬盘序列号，上面的方法都不行啊？
有谁有解决之道。

的却，上面的方法，在Win98下不行的，2000／XP都可以
// Version Windows 95 OSR2, Windows 98
hDevice := CreateFile('\\.\SMARTVSD', 0, 0, nil, CREATE_NEW, 0, 0); 对于Win98，是无效句柄！Win98SE没有对象\\.\SMARTVSD的
。
Up

//==============================================================================

//==============================================================================
function GetHardDiskSerial(Drive: string): string;
var VolumeSerialNumber: DWORD;
    MaximumComponentLength: DWORD;

  GetVolumeInformation(PChar(Drive), nil, 0, @VolumeSerialNumber, MaximumComponentLength, FileSystemFlags, nil, 0);
  Result := IntToHex(HiWord(VolumeSerialNumber), 4) + '-' + IntToHex(LoWord(VolumeSerialNumber), 4);
end;

如像realist(现实) 提供的方法可以，但不知在win95,winMe中是否可用？

98下不能取道硬盘序列号
我也很想知道这个问题

}Win9X的代码有问题，详情如下。感谢这位大哥的指点。NowCan: 你的FOR 9x的代码有问题，读从盘要么死机、要么读不出，应该象BCB_FAN的代码那样根据是主盘还是从盘调整参数。你的有问题的代码如下
static void ReadIDE()
{
int al;
int i;WaitIde();
outp(0x1F6,0xA0); <=========主盘是0xA0，从盘是0xB0，
al = WaitIde();
if ((al&0x50)!=0x50) return;outp(0x1F6,0xA0); <========= 但这里却不进行区分，直接使用0xA0
outp(0x1F7,0xEC); <========= 这个也有可能有问题
对于ATA设备，是0xEC，
但对于ATAPI设备，则为0xA1
al = WaitIde();
if ((al&0x58)!=0x58) return;for (i=0;i<256;i++) {
