majestic,

=== Add the following code in module1 ===
Public Declare Function GetVolumeInformation& Lib "kernel32" _
Alias "GetVolumeInformationA" _
(ByVal lpRootPathName As String, ByVal pVolumeNameBuffer As String, _
ByVal nVolumeNameSize As Long, lpVolumeSerialNumber As Long, _
lpMaximumComponentLength As Long, lpFileSystemFlags As Long, _
ByVal lpFileSystemNameBuffer As String, _
ByVal nFileSystemNameSize As Long)

Public 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

=== Add this code in form1 ===
Private Sub Command1_Click()
 Msgbox "Drive C Serial Number is " & Hex(DriveSerial("C"))
End Sub
