Connecting and Disconnecting Drive Cables When removing a cable with a pull-tab, grasp the colored pull-tab and pull until the connector detaches. When connecting and disconnecting a cable without a pull tab, hold the cable by the black connector at each end. Hard Drive CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide. CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before removing the computer cover. NOTICE: To avoid damage to the drive, do not set it on a hard surface. Instead, set the drive on a surface, such as a foam pad, that will sufficiently cushion it. Removing a Hard Drive 1 If you are replacing a hard drive that contains data you want to keep, back up your files before you begin this procedure. 2 Check the documentation for the drive to verify that it is configured for your computer. 3 Follow the procedures in "Before You Begin" on page 21. 4 Remove the computer cover (see "Removing the Computer Cover" on page 27). 5 Disconnect the power and data cables from the drive.
