Setting The Jumpers - Maxtor Installation Manual

Setting the Jumpers

A jumper is a small plastic piece that slides over a pair of configuration pins. (See Figure 4.)
The next step in the installation process is to set the jumpers on the back of your hard drive so
your system can identify the hard drive.

The following definitions describe the jumper settings:
Master. This setting can be used if you will be using the new hard drive as a primary master
boot drive or a secondary master additional storage drive. The hard drive should be connected
to the black (master) connector at the end of the ATA cable.
Slave. This setting can be used if you will be using the new hard drive for additional storage
only and is not typically used for boot devices on Windows-based systems. The hard drive
should be connected to the gray (middle) connector on the ATA cable.
Cable Select. This setting is an alternate method of hard drive identification that can be used
instead of the master and slave settings. With cable select enabled, all hard drives positioned on
the black (master) connector of the ATA cable will identify as master, and all hard drives
positioned on the gray (middle) connector will identify as slave.
To properly configure cable select, all devices on the same ATA cable must use the cable select
jumper setting and be connected with an 40-pin Ultra ATA cable like the one included.
Before installing a new hard drive, Maxtor recommends that you check to see if any device
currently attached to the ATA cable you wish to use is configured as cable select. You may need
to consult the documentation for this device or its manufacturer for jumper configuration
information.

Older systems that do not support Ultra ATA/66 speeds or are dated prior to November
1998 may not be able to use the cable select jumper option. If you are uncertain whether
your system can use the cable select option, use the master/slave settings instead.
