Dell Inspiron laptop computers run the Windows XP, Vista or 7 operating systems, depending on how old the computers are. Each of these operating systems has a built-in command that you can use to erase a hard disk on the Inspiron computer and format it so that it is just like new. This process does delete all of the data on the drive, and the only drive you can’t use it on is the main system partition, since you can’t erase a partition that is in use. Writer Bio
