Depending on whether you are formatting your master hard drive or slave hard drive the ways of formatting will differ.Simply go to my computer then right click the specific hard drive you want, then format your hard drive via command prompt.Click the start button click run go to after going to command prompt just type cmd. You can now format from here by simply typing format followed by the drive letter
