5 Release the drive bay by pulling the latch out away from the chassis and then sliding
the drive part way into the front of the chassis. (The latch drive brackets secure the
drives in their respective positions in the chassis.)
6 Connect the power and data cables from the back of the optical drive you want to
add. Reconnect the sound cable, if present.
WARNING: For a second Parallel ATA drive, make sure to connect the data
cable labeled Master to the primary hard disk drive, and the data cable
labeled Slave to the secondary hard disk drive. If the data cable is not
connected correctly, the PC is unable to locate the hard disk drive and data
may be lost.
