    Fix size off by one sector with unrecognized disk label (#649444)
    
    On disks with an unrecognized disk label, the end sector value
    was saved as one sector larger than actual.  This caused the
    Partition Information dialog to report the end sector value and
    the total number of sectors on the disk as one larger than the
    actual value.
    
    Closes Bug #649444 - Partition information reports wrong sector
                         count
