That used spaced was reserved for root by mkfs when the
partition was created. The mkfs command displays a message to that effect.
When you create a partition mkfs says something like (numbers for example only):
"66970 blocks (5.00%) reserved for the super user"

You can change the reserved block count percentage to 0% for a partition
you already created with:
	# tune2fs -m 0 /dev/sdaX

Or, create the filesystem with:
	# mkfs -t ext2 -m 0 /dev/sdaX

man mkfs.ext2
       -m reserved-blocks-percentage
              Specify the percentage of the filesystem blocks reserved for the
              super-user.   This  avoids  fragmentation, and allows root-owned
              daemons, such as syslogd(8), to continue to  function  correctly
              after non-privileged processes are prevented from writing to the
              filesystem.  The default percentage is 5%.

So, its a good thing to have that reserved space.
The disk is big enough, let it be.
