hello! as i see... you forgot your password or something like that? well... if its that... its simple to unlock it... at first make sure you can use your iPod as a hard drive, you can do it by conecting it to the pc and changing it in iTunes. then go to My computer>iPod Classic (or the name you gave it)> then key ALT >go to folder options>click allow show hidden content>then go to iPod control folder>device> and delete the _locked. then your iPod is unlocked!
