YOUTUBE At first, click start, Right click the "computer" option and choose "manage" which opens the "computer management" window. On the left explorer pane, click the storage option and then choose disk management which brings you a list of all available hard drives that you are using in your system. Before doing a format, make sure you have a backup of all your files since formatting will erase the entire contents of the specified drive. Right click the drive you wish to format and choose "format" and in the window that appears, choose the type of formatting option which is either NTFS or FAT32. Choose any one of them and make sure that "perform a quick format" is checked (a tick mark should be enabled). Then finally click the OK button to start formatting and wait for a few minutes for the formatting to complete.
