Installing Additional Drives

The computer has two external drive bays. When installing additional drives, follow these guidelines:

■The primary Serial ATA (SATA) hard drive should be connected to the primary SATA controller on the system board (blue and labeled P60 SATA 0). Connect a second SATA hard drive to the secondary SATA controller on the system board (white and labeled P61 SATA 1). HP does not support connecting both SATA and 3.5-inch PATA hard drives on the same system.

■Connect Parallel ATA (PATA) expansion devices, such as optical, IDE tape, and Zip drives, to the PATA controller (labeled P20 PRIMARY IDE) using a standard 80-conductor cable.

■Install guide screws to ensure the drive will line up correctly in the drive cage and lock in place. HP has provided extra guide screws (four 6-32 standard screws and four M3 metric screws), installed in the front of the chassis, under the computer cover. The hard drive uses 6-32 standard screws. All other drives use M3 metric screws. The HP-supplied metric screws are black and the HP-supplied standard screws are silver.

ÄCAUTION: To prevent loss of work and damage to the computer or drive:

■If you are inserting or removing a hard drive, shut down the operating

system properly, then turn off the computer. Do not remove a hard drive while the computer is on or in standby mode.

■Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector. For more information about preventing electrostatic damage, see Appendix D, “Electrostatic Discharge.”

■Handle a drive carefully; do not drop it.

■Do not use excessive force when inserting a drive.

■Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic fields such as monitors or speakers.

■If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective packaging and label the package “Fragile: Handle With Care.”
