Missing 2GB??

[silbeej]

So i'm missing 2 GB on my MBP hard disk. Is there some sort of restore feature like windows, or what is using this space that i can not find. Also, i have 18GB usage, jsut for the system. Is this a lot, for i have nothing on my MBP, and i still have 18GB for just applications, system, and library. is there a way to clean off all the crap i don't want?

Thanks
