Do you need to format a new primary hdd before installing windows?

Hello friends i have tried researching but i am finding conflicting responses, straight to the point, i get a new primary hdd tomorrow to replace one which is failing to boot, do i need to slave it first on another system and format it or can i just put the new hard drive into the laptop without formatting and hope the OS finds the drive and allows me to install windows? I know the install formats the drive but if the hdd is blank does it even contain a file system? i dont think windows will even see the drive to allow an install if it doesn't contain a file system.

    Just throw the drive in, boot from disc, install Windows, and you'll be golden. You don't need to mess with it first.
