That's it! Your hard drive has been formatted and it's ready for use in Windows 7. You can use the new drive however you want - backup files, store music and videos, etc.
If you'd like to change the drive letter assigned to this drive, now is the best time to do that. See How To Change Drive Letters in Windows 7 for help.
Important: Assuming you chose to quick-format this hard drive, which I advised against in a previous step, please remember that the information on the hard drive isn't truly erased, it's just hidden from Windows and other operating systems. This is probably a perfectly acceptable situation if you're planning on using the drive again yourself after the format.
However, if you're formatting a hard drive because you're planning on removing it to sell, recycle, give away, etc., follow this tutorial again, choosing a full format, or see How To Wipe a Hard Drive for some other, arguably beter, methods of completely erasing a drive.
