DVDFab gives problem while copying DVD files

I installed this software to make a complete backup of my DVD movie “The Transformers” with version 0.16. I ripped my DVD with DVDDecrypter and selected to copy complete DVD in this software.
Now when it starts to copy the menus etc, the following error message is displayed
An error occurred:
An sector was not found(00002001)

Please someone tell me what this error is about and how to solve it.
