Don't know what operating system your using but in Windows 7 and up it's easy to partition any drive even while windows is running.
Go to --> Control Panel\Administrative Tools\Computer Management\Disk Management and right click - set the size.
You can change it any time as long as whats in it isn't bigger than the size you want to make it. I have a 1 TB in this computer and that's how I did it after discovering that my old drive tools didn't work on this.
For any info on this procedure (or darn near anything you can think off) you can always go to youtube for step by step instructions.
Just watch a few first because some people are better teachers than others.
