You can use 'tune2fs -l /dev/sdb1' to tell you the inode size assuming
ext2/3. For me that's 128 bytes which would indicate about 1GB for you.
This however should not show up in df.
The space is probably taken up by reserved blocks. These are blocks
which are reserved for root's use; normally about 5%, or ~3GB in your
case. You can view and tune the value with tune2fs.
The rest is probably just rounding on the part of 'df -h'.
