8.0 Installation

The first thing to do when installing a drive is to set the drive ID (select) on the SCSI bus and set up certain

operating options. This is usually done by installing small shorting jumpers on the pins of connectors J01, J4A,

and J4B on the PCB. Some users connect cables to the jumper headers and perform the set-up using remote

switches.

If your system is “SCAM” (SCSI Configured Auto Magically) compliant, the system assigns the drive ID over the

interface, so there is no need to be concerned about drive ID. Setting the drive ID jumpers doesn’t hurt any-

thing, but is not necessary.

If your system is not “SCAM” compliant, you do need to set the drive ID using the ID jumpers.

Configure drive options

For option jumper locations and definitions refer to Figures 8, 9a, and 10a. Drive default mode parameters are

not normally needed for installation. Refer to Section 9.3.2 for default mode parameters if they are needed.

• Ensure that the SCSI ID of the drive is not the same as the host adapter. Most host adapters use SCSI ID 7.

ID 7 is the highest priority on both 8 and 16 bit data buses.

• If multiple devices are on the bus, set the drive SCSI ID to one that is not presently used by other devices on

the bus.

• If the drive is the only device on the bus, attach it to the end of the SCSI bus cable. Permanently installed ter-

minators must be enabled on the drive for “N” and “W” models using jumper plug TE if termination is not pro-

vided by the host equipment. On “WD” models, external terminators must be provided by the user, systems

integrator or host equipment manufacturer.

• If the drive is attached to a bus that contains other devices and the new drive is not attached to the end of the

bus, the Terminator Enable jumper (TE) should be removed from the new drive.

Note. For additional information about terminator requirements, refer to Sections 9.8 and 9.9.

• Set all appropriate option jumpers for desired operation prior to power on. If jumpers are changed after

power has been applied, recycle the drive power to make the new settings effective.

• Installation instructions are provided by host system documentation or with any additionally purchased drive

installation software. If necessary, see Section 10.0 for Seagate support services telephone numbers.

• Do not remove the manufacturer’s installed labels from the drive and do not cover with additional labels, as

the manufacturer labels contain information required when servicing the product.

Formatting

• It is not necessary to low level format this drive. The drive is shipped from the factory low level formatted in

512-byte sectors.

• Reformat the drive if a different spare sector allocation scheme is selected.

• High level formatting the drive involves assigning one or more partitions or logical drives to the drive volume.

Follow the instructions in the system manuals for the system into which the drive is to be installed.

• Systems that have Windows 95 Operating System version 950B (this has FAT32) or later do not need to par-

tition the drive.

8.1 Drive ID/option select header

Figures 8, 9a, and 10a show views of the drive ID select and option select jumper connectors. The notes fol-

lowing the figures describe the functions of the various jumper positions on the connectors J01, J4A, and J4B.
