Hi,
Try this:

Private Sub Workbook_Open()
  Dim SerialNumber As String
  SerialNumber = CreateObject("Scripting.FileSystemObject").Drives("C").SerialNumber
  If SerialNumber = Me.Sheets("Username").Range("A1").Value Then
    MsgBox "Wellcome " & Environ("UserName")
  Else
    MsgBox "Hello " & Environ("UserName") & vbLf _
         & "Sorry, but your can't use this workbook!", _
            vbExclamation, "Close"
    Me.Close False
  End If
End Sub

You are welcome! Negative serial number is native, but you may use its absolute value as well:
SerialNumber =Abs(CreateObject("Scripting.FileSystemObject").Drives("C").SerialNumber)
