    Set NTFS minimum partition size to 2 MiB (#697848)
    
    The minimum NTFS volume size supported by the ntfs-3g mkntfs command
    is 1 MiB.  Since 1 extra sector is required for the backup NTFS boot
    sector, an NTFS partition must be at least 1 MiB plus 1 sector.
    
    To demonstrate, create a 1 MiB unformatted partition using MiB
    alignment (/dev/sdd1), and then try to format the partition as NTFS.
    
    # mkntfs -Q -v -L "ntfs-test" /dev/sdd1
    Device is too small (1023kiB).  Minimum NTFS volume size is 1MiB.
    
    For GParted this means a minimum NTFS partition size of 2 MiB since
    the smallest unit in the GUI is MiB.
    
    Bug #697848 - Failure to Create 1 MiB NTFS Partition
