Since then there have been many more changes than that to
the GPT-handling code.  Please look at the latest, give it a try,
and if something doesn't work, report it with enough detail
to reproduce the problem.

In interactive mode, you should get a prompt like this:

         _("The backup GPT table is not at the end of the disk, as it "
           "should be.  This might mean that another operating system "
           "believes the disk is smaller.  Fix, by moving the backup "
           "to the end (and removing the old backup)?")))
