Removal and Replacement Procedures
Drives
This chapter describes the procedures for removal and replacement of hard drives. For an
overview of the Convertible Minitower chassis, refer to Chapter 6 “Identifying the Chassis,
Routine Care, and Disassembly Preparation.”

WARNING: Power is applied to the system board and power supply even when the power switch is
turned off. To prevent damage to the unit, disconnect the power cord from the power source or the unit
before beginning disassembly procedures.
9.1 Introduction
When installing additional drives, follow these guidelines:
■ For optimal performance, connect hard drives to the primary controller. Connect expansion
devices, such as CD-ROM, IDE tape, and diskette drives to the secondary controller.
✎
Refer to Chapter 4 for more detailed information on Ultra ATA drives and to Chapter 5 for SCSI
drives.
■ You must install guide screws to ensure that the drive lines up correctly in the drive cage.
Extra guide screws are provided that are installed in the front of the computer chassis behind
the front bezel. Some options require metric hardware. Factory-supplied metric screws are
black.
■ Drive installation requires no jumper setting changes on the existing or optional drives. All
factory-installed drives have the jumpers preset for cable-select installation.
■ The system automatically recognizes hard drives any Plug and Play hard drive and will
automatically reconfigure the computer. If you installed a hard drive that is not a Plug and
Play device, you must run Computer Setup to reconfigure the computer.
✎
If installing a second device on the primary controller, you must use an 80-conductor Ultra ATA
cable for optimal performance. This cable is available as an HP option.

CAUTION: When servicing the computer, ensure that cables are placed in their proper locations during
the reassembly process. Improper cable placement can damage the computer.
