Installing Additional Drives

Ä
2–22
The computer supports up to six drives which may be installed in
various configurations.
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 (labeled P61 SATA 1). Connect a third SATA
drive to P62 SATA 2 and a fourth SATA drive to P63 SATA 3.
■
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.
■
You may install either a third-height or a half-height drive into a
half-height bay.
■
You must 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 with the computer. The hard drive uses 6-32
standard screws, four of which are installed on the hard drive
bracket under the access panel. All other drives use M3 metric
screws, eight of which are installed on the diskette drive bracket
under the access panel. The HP-supplied metric screws are black.
The HP-supplied standard screws are silver.
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, refer to
"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
protective packaging and label the package "Fragile: Handle With Care."
