trouble converting ipod 5th gen 80gb to FAT32

[miacrow]

i am following the tutorial on
http://www.rockbox.org/twiki/bin/view/Main/IpodConversionToFAT32
 i am pretty unfamiliar with the language being used, but i am ok until i get to step c.  i do everything the instructions say to do but once i run this command
dd if=mbr-video80gb-2048.bin of=/dev/ipod1
i get this message
dd: /dev/ipod1: Permission denied
 does anyone know what to do

You don't have the required permissions, as the error message says. Get them Usually you can do this by becoming root.

what are these permissions that i need? how would i go about getting them?  what is root?
