    Fix problem reading some FAT32 partitions (#605175)
    
    This problem was introduced with GParted 0.4.7 when the "-a"
    option was removed from the dosfsck command.  The dosfsck command
    is used to read the number of used sectors.  Instead we will now
    use the "-n" option which does not write any changes to the file
    system, and allows non-interactive operation.
