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 (labeled P60
SATA 0). Connect a second SATA hard drive to the secondary
SATA controller on the system board (labeled P61 SATA 1). HP
does not support connecting both SATA and 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.
Ä CAUTION: 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 E, “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.”
