usb hard disk has 57% usage after formatted...

I just re-formatted a 120GB usb hard disk with a FAT32-LBA fs, and It always shows an usage of 57% even if it has data or not...
df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sdb1             115G   66G   50G  57% /mnt/usb-storage
How can I have the system to have usable the whole 115GB of that usb device?

Sometimes df may calculate free space incorrectly. Use du and subtract the used amount with maximum data capacity.

What format options did you use for mkdosfs?
