## better then recently code
if [ ! -n "$1" ]
then
  echo "Error, input the Raspberry Pi SD" \
       " card Device information ex) \
        sudo bash $(basename $0) /dev/sdb" && exit 1
fi

## Error Fix
mountCheck=$(mount -l | grep $piDev | grep boot | awk {'print $2'})

## Error Fix
used=$(df -k | grep media/pi | awk {'print $3'}) 

## inode data..
df -i /media/pi
