Back up all important files from the hard drive, as reformatting a drive permanently erases all data on the disk and cannot be undone.
Hold the Windows key, and press the R key. This opens a window labeled Run.
Clear out the entry field in the Run window and type "control admintools." Click OK, or press the Enter key.
In the Administrative Tools window, double click on the shortcut labeled Computer Management.
On the left-hand panel of the Computer Management window, click on Disk Management under the Storage item.
Look for the drive you'd like to format in the list of drives. The Volume column lists them by drive name in alphabetical order. Right click on its icon on the list, and select Format.
In the Format window, supply a name for the drive, and select a file system to use. Optionally, you may choose to change the allocation unit size, perform a quick format or enable file and folder compression. Click the OK button to begin the reformatting process.
