Trying to add a new Hard Drive

[youreaduck]

Hi, I got a hard drive from my step-dad and I'm trying to format it, in some way so I can put stuff on it, but all the options are grayed out and are un-clickable except the 'help' button, which isn't any help, If someone tells me how, I can post a screen shot, thanks to anyone who helps.

I figured out it was my Hard Drive had a protective partition on it.
