4.Disconnect the power supply connector from the socket on the back of the hard disk drive, as shown below. Firmly pull the connector straight out from the socket so you do not bend the pins. Do not pull too hard on the cable; pull on the plastic connector, if possible.
5.Remove the ribbon cable connector from the back of the drive in the same manner, as shown above.
If you removed the drive because you are going to install or remove a drive in a horizontal drive bay, follow the instructions under “Installing or Removing a Disk Drive in the Horizontal Position” on the next page. Do not perform steps 6 through 8.
If you are not going to reinstall the hard disk drive you have just removed, go to step 6.
6.Remove the four screws securing the hard disk drive mounting plate to the hard disk drive. Then remove and store the mounting plate along with the screws.
