Medalist 1270 Installation Guide, July 1995 1

Introduction

Thank you for choosing a Seagate® drive. The purpose of this guide is to assist you with installing your new hard drive. Its organization outlines the complete installation process from handling the drive and drive application in Before you begin... to offering troubleshooting suggestions and technical support information. The topics discusses are:

• Handling your drive (see Before you begin...)

• Configuring the drive

• Attaching cables to the drive

• Mounting the drive

• Configuring the computer

• Troubleshooting

• Where to call for Seagate technical support

Seagate provides installation software, EZ-Drive, and a 32-bit disk access driver for Windows, SEG32BIT.386, that allows the computer to surpass the 528-Mbyte barrier when it is imposed. The software is stored on the drive and must be transferred to a diskette in Drive A before you partition and format the drive. A program called Seamove is provided to make the transfer easy.

We hope your installation goes smoothly, but if complications arise, a list of common symptoms and solutions is provided in the troubleshooting section. If the problem persists, contact your dealer first. Your dealer is familiar with system integration and the conflicts that arise. If you need additional help or information about Seagate products, Seagate technical support numbers are provided.

Before you begin...

Note. Throughout this manual the Medalist 1270 is referred to by

its model number, ST31270A.

Drive handling. Your drive is vulnerable to damage from rough handling and static discharge. Do not drop your drive. Do not remove the seals and labels on the drive. The drive warranty is voided if the seals and labels are removed.

Static discharge. Your drive contains components that can be damaged by static discharge. Static damage can be cumulative and may not manifest immediately. Observe the following precautions:

• Ground yourself before handling the drive. Wear a ground strap that is properly connected to earth ground, or touch the metal of a power supply that is plugged into a wall outlet while handling the drive.

• Keep the drive in its antistatic bag until you are ready to install it. Do not attach any cables to the drive while it is in its bag.

• Handle the drive gently and only by its edges or frame. Place it on an antistatic surface until you are ready to install it.

• Do not touch the drive’s connector pins or printed circuit board.

Inspection. Use the handling precautions listed above when you inspect the drive. If it appears to be damaged, call your distributor or dealer immediately.

Warranty. The drive comes with a three-year limited warranty. Note. With regards to the EZ-Drive and SEG32BIT.386 software,

there are no warranties, express or implied, including, but not implied, warranties of merchantablity or fitness for a particular purpose. All such warranties are expressly and specifically disclaimed.

Maintenance and repair. Seagate drives do not require maintenance. The head/disc assembly is sealed; a broken seal voids the warranty. Seagate customer service centers are the only

4 Medalist 1270 Installation Guide, July 1995 facilities authorized to repair Seagate drives. Seagate does not

sanction any third-party repair facilities. Application. Your Seagate drive is designed for IBM AT and

compatible personal computers. It uses the ATA interface. It is intended for use with UL-listed computers or similar products.

Medalist 1270 Installation Guide, July 1995 5 Warning. Turn off the computer before you remove its cover.

Turn off the power before you install or remove any adapter card or the drive.

Caution. Special training or tools may be required to service

laptop computers. Removing the cover may void your warranty. Review the terms and conditions of your warranty before removing the cover.

Configuring the drive

Required materials:

• 0.100-inch jumper connectors (supplied as spare jumpers)

Your Seagate drive is configured using the options jumper block shown in Figure 1 on page 6. You can configure the drive:

• For one- or two-drive operation

• To be the master or slave drive

• For dual-drive emulation

• To operate as the master with drives that use a different

master/slave timing protocol

• For computers that use cable-select

• To use a remote drive-activity LED

To configure the drive, attach a jumper to the pins on the options jumper block as shown in Figure 2 on page 7 for the desired option. The configuration options are:

Spare jumper. Use the spare jumpers on pins 1 and 3 and pins 5 and 7 to configure the drive. These settings are not used for drive operation.

One-drive only. Use this configuration if there are no other drives attached to the hard disc controller.

Master with slave present. Use this configuration if the drive is the first of two drives in your system. The master drive is drive 0 in the System Setup record.

Slave. Use this configuration if the drive is the second drive in the system. The slave is drive 1 in the System Setup record.

Master/slave timing protocol. This protocol involves the communication between the computer and the disc drives during the power-on cycle only. The computer queries the master drive for the status of both drives. The slave must report its status to the master within a certain time period. If it does not respond in time or if it uses a response signal that the master does not acknowledge, the master tells the host that the slave has timed out, and the computer does not recognize the slave. The Seagate drive is shipped configured to work with other drives that comply with the ATA-standard master/slave timing protocol.

This setting allows the Seagate drive in the slave position to respond to some drives that use a different protocol. Try using this setting if the slave is not identified after power-on.

Dual-drive emulation. This feature allows you to make the most of the BIOS limitation by making the drive two logical drives for the computer. Each logical drive is assigned a drive type in System Setup using the maximum translation geometry values the BIOS allows. Each logical drive must be partitioned and formatted. A second, physical drive cannot be attached to the hard disc controller. You cannot use dual-drive emulation with cable select.

Cable-select. Use this configuration if your computer uses cable-select.

Remote LED. If your computer uses a remote drive-activity LED, place the ground wire side of the connector, usually the black wire, on pin 13 (–) and the other side on pin 14 (+) of the options jumper block. The LED can be damaged if the cable is attached incorrectly.

The options jumper block accepts a 0.100-inch connector. It may be necessary to replace the current connector on the LED cable with a 0.100-inch connector.

Medalist 1270 Installation Guide, July 1995 9

Attaching the cables

Required materials:

• A 40-conductor interface cable with a 40-pin, female interface connector for each drive you want to attach.

• A four-conductor power-supply cable. Note. To ensure the integrity of your data, use a nonshielded

cable with a maximum length of 18 inches (46 centimeters).

This section refers to Figure 1 on page 6.

1. Attach the interface cable. Pin 1 on the drive must align with pin 1 of the hard-disc controller connector. Use the edge-stripe on the cable to denote pin 1. Pin 1 on the drive is located next to the four-pin power connector.

Caution. The cable and connector bond is delicate. Pulling the

cable to remove the connector may damage the cable.

Attach an interface connector to the drive. If your interface connector has a key, it can only plug into the drive one way. Be sure that you do not bend the pins when you attach the cable.

Attach an interface-connector to the hard-disc controller connector on the motherboard or host adapter. Be sure that pin 1 (see your system user’s guide or host adapter user’s guide to determine the location of pin 1) is aligned with pin 1 on the drive.

Cable-select installation: If your computer uses cable-select, refer to its user’s guide to determine which interface connector is used for the master and which is used for the slave.

2. Attach a power-supply cable to the drive.

Caution. The cable and connector are designed to mate. Do not

force a connection. Improper alignment can damage your drive.
