Connecting the hard disk drive cables
After you replace the bracket, you need to connect the cables to
the hard disk drive. Follow these steps:
1. Locate one of the IDE device cables that are connected to
the IDE interfaces on the system board. They are flat cables
with a system board connector on one end and two IDE
device connectors on the other end. A red wire runs down
one side of the cable. (See “Locating System Board
Components” in Chapter 4 to find the primary and
secondary IDE interfaces on the system board.)
Use the primary IDE interface for your boot drive and your
second hard disk drive; use the secondary IDE interface to
connect IDE CD-ROM drives, other IDE devices, or your
third and fourth drives. You cannot connect a CD-ROM
drive and hard disk drive to the same interface.
