To defragment your disk storage, do the following: 1. Right-click the icon for the hard disk drive (HDD) that you want to reorganize, then select Properties from the pop-up menu. Go to the Tools tab from disk Properties and select Defragment Now. [. . . ] Check to determine if there is an optical drive icon in the resource manager of the operating system.
