Shows the following information for the logical disk: Drive letter, Total size of the logical disk, Current space used on the logical disk.

You can control the contents and appearance of the Disk panel

  • Right-click the panel and selecting Configure Disks Display.
  • To stop Spotlight from showing disk containers in the Disks panel, right-click a disk container and clear the Show Disk Containers option.
