The method of formatting a hard drive depends on many factors. Is this a primary drive that you will be putting an operating system on? Is it a secondary drive that will be used to increase your storage capacity? What operating system are you using? I will assume you are wanting to format a primary drive. once the drive in installed in the computer all you need to do is boot from the setup disk for the operating system you will be using and follow the onscreen prompts. If this is a secondary drive you would format in the same way as a floppy or CD.
