Got a new computer... should I partition my hard drive and how?

[TheMetetron]

Just got a new computer. I'm completely cluess.... should I partition my drive (I don't even know how to do this). FWIW, I have a 250 gig internal and a 250 gig external. The external holds all my media files (documents, photos, music, dvds). Right now the internal just has a few programs and will soon hold my new PT database (SQL).

Thanks for the help.
