用diskid.dll和disk32.dll获得硬盘序列号

       今天夜里两点，还没有入睡，就把取得序列号的代码简单写了一下，没有分别在不同的系统上调试，只在win2000下调试通过，如果有问题的话，请告诉我，我再修改

1.调用diskid.dll实现：

Option Explicit
Private Declare Function IsWinNT Lib "DiskID.DLL" () As Long
Private Declare Function ReadPhysicalDrive9X Lib "DiskID.DLL" (driveID As Long, buffer As Long, bufLen As Long) As Long
Private Declare Function ReadPhysicalDriveInNT Lib "DiskID.DLL" (driveID As Long, buffer As Long, bufLen As Long) As Long

Private Type DRIVER_INFO_OK
    ModalNumber(39) As Byte
    SerialNumber(19) As Byte
    ControlNum(7) As Byte
    DriveType As Long
    Cylinders As Long
    Heads As Long
    Sectors As Long
End Type

Private Sub Command1_Click()
    Dim x As DRIVER_INFO_OK
    Dim i As Long
    If IsWinNT = 1 Then
