How Could I do this

Changing Hdd Serial Number

You mean the Volume Serial Number?

I use a program called VolumeID, you can find it here

Why would you want to do that?

By the way could anybody tell me how to read volume id of a harddisk

[BrianS]

Private Declare Function GetVolumeInformation Lib "Kernel32" Alias "GetVolumeInformationA" (ByVal lpRootPathName As String, ByVal lpVolumeNameBuffer As String, ByVal nVolumeNameSize As Long, lpVolumeSerialNumber As Long, lpMaximumComponentLength As Long, lpFileSystemFlags As Long, ByVal lpFileSystemNameBuffer As String, ByVal nFileSystemNameSize As Long) As Long
Private Const MAX_FILENAME_LEN = 256
Public Function DriveSerial(ByVal sDrv As String) As Long
    Dim RetVal As Long
    Dim str As String * MAX_FILENAME_LEN
    Dim str2 As String * MAX_FILENAME_LEN
    Dim a As Long
    Dim b As Long
    Call GetVolumeInformation(sDrv & ":\", str, MAX_FILENAME_LEN, RetVal, a, b, str2, MAX_FILENAME_LEN)
    DriveSerial = RetVal
End Function
Private Sub Form_Load()
    MsgBox "Serial of drive C is " & DriveSerial("C")
End Sub

Damn! I have just created a program that uses the filesystem object to read the drive serial (??volume id??) to authenticate the program.

Does this mean that you cannot authenticate a program to run on a single machine using the volume ID and another secret key??

Doesn't BrianS' code work?

How is the Volume Serial Number stored on the drive? - is it stored in some form of a EPROM on the hard drive or is it stored on the drive itself?

If it were stored on the drive itself then I would assume there could be a possibility of being able to change it. A guy I know used to program in assembler and could actually finetune the old systems to run faster by modifying the actual locations on disk where the data would usually be stored!!!

The FileSyste Object only reads the Format Serial number ...(the one that changes each time you format your HD or FD)

the other serial number a HD has ...is the Factory Serial Number ...(that is stored in the BIOS of the HD) and it is not possible to alter in any way ...not easy to aquire aswell using Visual Basic ...you need a DLL that is made in C++ with the instructions to access the hardware information (MS has also somethign to do that ...but it´s a lot of work...and couldn't find the way to make it work )

[BrianS]

You can change it (Volume S/N), with the program I posted earlier, unless you mean change it via VB code directly.

And I'm sure it's stored on the HD disk itself, like the Label.

D12Bit opened the can of worms - BrianS, I am assuming you can change the Volume Serial Number, but in order for me to create really locked down apps I would need to get the factory serial...would be really nice if this could be done, but I can imagine that since this number is not on the HD, it must be accessed in a totally different way. Like 'how would I even be able to access that section of memory!!!'

[D12Bit]

you can get the Factory HDD serial Number with a DLL that is available in the internet ...

as a matter of fact, this has been discussed here several times before ...do a serach for hdd serial number or factory serial number ... and you'll find the name of the dll and where to get it ...


Good luck!

[BrianS]

Use a Keygen method instead.

You will never get anything 100% secure, all you can do is try.
