Hardware Reference Manual

Installing and Removing Drives
When installing additional drives, follow these guidelines:
●
The primary Serial ATA (SATA) hard drive must be connected to the dark blue primary SATA
connector on the system board labeled SATA0.
●
Connect a SATA optical drive to the white SATA connector on the system board labeled SATA1.
●
Connect a second SATA hard drive to the next available (unpopulated) SATA connector on the
system board by following the numbered sequence of the connectors.
●
Always populate the dark blue SATA0 and white SATA1 connectors before the light blue SATA4
connector.
●
Connect a diskette drive to the connector labeled FLOPPY.
●
Connect a media card reader to the USB connector labeled MEDIA.
●
The system does not support Parallel ATA (PATA) optical drives or PATA hard drives.
●
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 for the external drive bays (four 6-32 standard screws
and four M3 metric screws), installed in the front of the chassis, under the front bezel. The 6-32
standard screws are required for a secondary hard drive. All other drives (except the primary hard
drive) use M3 metric screws. The HP-supplied metric screws are black and the HP-supplied
standard screws are silver. If you are replacing the primary hard drive, you must remove the four
silver and blue 6-32 isolation mounting guide screws from the old hard drive and install them in the
new hard drive.
