PATA Hard Drive Installation
Guidelines
For more information about Serial ATA (SATA) devices, refer to the white paper
“Implementation of Serial ATA on HP Business Desktops”. The white paper is

Using the Cable-Select Feature with Parallel ATA
(PATA) Devices
Optional drives are available from HP in kits that include a special drive cable. The
configuration of the drive employs a cable-select feature that identifies the drive as
device 0 (primary drive) or device 1 (secondary drive).
Device 1 is the drive connected to the cable’s middle connector. Device 0 is the drive
connected to the cable’s end connector (applies only to 80-conductor ATA cables).
See “Guidelines for Installing PATA Drives” in this appendix for an example of an
PATA cable.
HP hard drives ship with jumpers preset to cable-select mode; therefore, no jumper
setting changes on the existing or optional drives are required. If you purchase a
third-party hard drive, refer to the documentation included with the kit to ensure
proper installation and configuration of cables.
If installing a second device on the primary controller, you must use an 80-conductor
PATA cable for optimal performance. This cable is standard on select models.
