SING DISCWIZARD

DiscWizard is a revolutionary new Windows program that makes it easy to install your new Seagate drive. DiscWizard helps you configure your new drive and your computer . It analyzes your system, lets you select various installation options and creates customized step-by-step instructions. It also allows older computers to access the full capacity of your drive.

You can run DiscWizard to install your new hard drive if:

• Y ou already have an existing, bootable hard drive in your computer with at least 3 Mbytes of available disc space

• Y ou are running Windows 3.x or Windows 95.

If you can run DiscWizard, you do not have to read this installation guide. Instead,

the instructions on the DiscWizard diskette to install your drive. DiscWizard provides all the information you need to install your new drive.

If you cannot run DiscWizard, follow the instructions in this installation guide to install and configure your new drive. For additional information and troubleshooting tips, see the back of this sheet. This symbol: cates that additional information on a topic appears on the back of this sheet.

If your new Seagate your computer , you do not have to change any jumper settings. In this case, skip ahead to “Attaching Cables and Mounting the Drive.”

If you already have one hard drive in your computer and you are installing a second drive, you must configure one drive as a master and the other as a slave. The master drive will be the “boot” drive (drive C), from which the computer loads system software when it first starts up. To configure your new Seagate drive as the master, slide a jumper onto pins 7 and 8 (see below). T o configure the drive as a slave, slide a jumper onto pins 5 and 6 only. The jumper on pins 6 and 8 is a spare and does not affect drive operation. If you need to change the jumpers on your existing hard drive, see the Disk Manager online manual, or contact the drive manufacturer .

TTACHING CABLES AND MOUNTING THE DRIVE

1 If you are installing a new AT A interface cable, attach one

end of the cable to the interface connector on your computer or host adapter . The A TA cable must be no mor e than 18 inches long.

2 Thread the interface cable through the drive bay and attach

the connector at the end of the interface cable to your new drive. If you have two drives, attach the second drive to the second connector .

Pin 1

Caution. Make sure to align pin 1 on the com-

puter or host adapter interface connector with pin 1 on your drive or drives. Pin 1 on the interface cable is usually indicated by a stripe along the edge of the cable.

HAT YOU WILL NEED

• Straight-edge and Phillips screwdrivers

• Drive mounting screws

• An ATA host adapter and interface cable (max. length: 18 inches) with enough connectors for all your drives

• An unused drive power cable for your new drive

• A bootable DOS system diskette (Seagate recommends using DOS Version 5.0 or later.)

• If you are mounting this 3.5-inch drive in a 5.25-inch drive bay, you need a mounting adapter or frame kit. Also, you may need drive mounting rails if your drive bay is not designed for direct mounting.

EFORE YOU BEGIN

• Make sure your computer is turned off before you open the case.

• Read the handling precautions at the right and inspect the drive to make sure that it is not damaged.

• Save your foam-lined Seagate disc drive box. This box has been approved by Seagate for shipping a Seagate disc drive. Using any other container or packing material voids your drive warranty.

ANDLE WITH CARE

Disc drives are extremely fragile. Do not drop or jar your drive.

Keep the drive in its antistatic bag until you are ready to install it.

Protect your drive from static discharge by making sure you are well-grounded before touching the drive. We recommend wearing a grounded wrist strap throughout the installation process. Do not touch the connectors or any part of the printed circuit board.

Always handle the drive by its edges or frame.

Do not apply pressure or attach labels to the circuit board or the top of the drive.

3 Slide the drive carefully into the drive bay. Secure the drive

with four 6-32 UNC-2A mounting screws in either the sidemounting holes or the bottom-mounting holes. Do not overtighten the screws. The screws should be inserted no more than 0.22 inch into the bottom mounting holes and no more than 0.14 inch into the side mounting holes. Do not use metric screws.

Note. If you are mounting the drive in a 5.25inch drive bay , you need a mounting adapter or frame kit. Contact your computer dealer . Some

computers also require drive mounting rails, which can be obtained from your distributor or computer manufacturer.

4 Attach a power cable to each drive. If your computer does

not have an unused power connector , you can purchase a Y -shaped power cable from your computer dealer .

5 Check all cable connections and then replace your com-

puter cover . Continue to step 2 below.

ONFIGURING YOUR COMPUTER

Before you format or partition your new drive, you must configure your computer’s BIOS so that the computer can recognize your new drive.

1 T urn your computer on. As your computer starts up, watch

the screen for a message describing how to run the system setup program (sometimes called BIOS or CMOS setup). This is usually done by pressing a special key, such as

DELETE, ESC

manual for details. Press the appropriate key to run the system setup program.

2 Enable LBA mode if it is available. Many BIOS use the logi-

cal block addressing (LBA) mode to access drives with capacities greater than 528 Mbytes.

3 If your BIOS provides automatic drive detection (an

“Auto” drive type), select this option. This allows your computer to configure itself automatically for your new drive.

If your BIOS does not provide automatic drive detection, select “User-defined” drive settings. If your computer supports LBA addressing, enter the LBA cylinder , head and sector values for your drive from the table at the top of the next column. If your computer does not support LBA addressing, enter the CHS values

, or

, during startup. See your computer

DDRESSING DRIVE-CAPACITY LIMITATIONS

Some DOS-based computers and operating systems are not designed to accommodate large hard disc drives. The three most common system limitations are listed below, along with methods for overcoming these limitations. See your system manual to determine which (if any) of these limitations applies to your computer .

528-Mbyte limit: The BIOS in some older computers cannot accommodate drives with capacities greater than 528 Mbytes. Seagate provides free Disk Manager software with your drive to overcome this limitation. Alternatively , you can purchase a hard drive controller or a BIOS upgrade that supports drives with capacities greater than 528 Mbytes.

The 32-bit disk access feature in Windows 3.1 does not work with drives that have capacities greater than 528 Mbytes. If you want to use 32-bit disk access with Windows 3.1, install the Seagate replacement 32-bit access driver , SEG32BIT .386, as described on the back of this sheet.

4,096-cylinder limit: The BIOS in some computers cannot support drives that have more than 4,096 cylinders.

install a drive that has more than 4,096 cylinders in one of these computers, the computer may “freeze” or fail to boot.

If you

Partition-size limit: not access drive partitions larger than 2.147 Gbytes. You can overcome this limitation using the Disk Manager software or the DOS FDISK command to divide your drive into several smaller partitions. Each partition acts as a separate logical drive, with its own drive letter . If most of your files are smaller than 50 Kbytes, you should divide your drive into partitions of 1 Gbyte or less to make the most efficient use of your disc space.

BIOS Upgrades: If you need to upgrade your BIOS, contact the appropriate BIOS manufacturer listed below.

Caution. Partitioning or formatting a drive

erases all data on it. Seagate assumes no liability if you erase your data.

Drive Partitioning

Partitioning a hard drive divides it into sections (partitions) that function as separate logical drives (labeled C, D, E, etc.).

Because DOS computers cannot access partitions larger than

2.1 Gbytes, you must divide large-capacity hard drives into

multiple partitions. In creating partitions, keep in mind that the larger the partition, the more drive space is taken up in unused clusters. For this reason, if most of your files are smaller than 50 Kbytes, you should use partitions of 1 Gbyte or less. To par tition your new drive:

1 Insert a bootable DOS diskette in your diskette drive and

restart your computer .

2 Insert a DOS program diskette that contains the FDISK.EXE

and FORMAT.COM programs into your diskette drive. At the A: prompt, type FDISK and press

3 If you have two hard drives installed, the FDISK menu

displays five options. Option five allows you to select the drive you want to partition. Make sure that your new drive is selected.

Cable Select Jumper

Some computers differentiate between master and slave drives using specially designed interface cables that have the line to pin 28 (the Cable Select pin) removed or cut at one connector. The connector that has pin 28 disabled is used for the slave drive. See your computer manual to determine whether your computer supports this feature. To configure your Seagate drive for cable select, place a jumper on pins 5 and 6 and pins 7 and 8 as shown below.

Remote LED Connection

You can connect a remote LED to pins 3 (–) and 4 (+) as shown in the figure below. Do not install a jumper on these pins. Because the jumper block uses a 0.1-inch connector, you may need to replace the current connector. Use Seagate connector part number 10562-001 or equivalent.

Booting from a Diskette

If Disk Manager installs the dynamic drive overlay (DDO) to access the full capacity of your drive, the DDO must load into memory before the operating system loads. This occurs automatically when you boot from your hard drive (drive C). However, if you boot from a diskette, the DDO will not be loaded and you will not be able to access your hard drive. The following procedure allows you to boot from a diskette and still access your hard drive.

Basic Troubleshooting

If you have installed your drive and it does not function properly, perform the following basic checks:

Warning. Always turn off the computer before changing jumpers or unplugging cables and cards. Wear a ground strap or take other antistatic precautions while working on your computer or handling your drive.

Verify compatibility. Verify that the host adapter and drive are

•

appropriately matched to each other and to your computer. Refer to the relevant documentation for details.

Check all cards. Verify that all cards are seated in their slots on the

•

motherboard and secured with mounting screws. Check all connectors and cables. Make sure all ribbon and power cables

•

are securely connected. Ribbon cables are easily damaged, especially at the connector. Try a new cable known to be good. Make sure no connector pins are bent. Verify that pin 1 on the interface cable is aligned with pin 1 on the drive and host adapter (see figures and instructions on the front of this sheet).

Verify jumper settings. Review the instructions on this sheet and in your

•

host adapter installation guide. Make sure all appropriate jumpers are installed or removed as necessary.

Check your power-supply specifications. Each time you add a new

•

device to your computer, make sure your computer’s internal power supply can support the total power demand. If necessary, consult your dealer for a new power supply.

Verify the drive-type settings in the system setup program. The drive-

•

type settings in the system BIOS must not exceed the physical specifications of your drive. Also, the settings must not exceed the limitations set by the operating system and BIOS.

Check for viruses. Before you use someone else’s diskette in your system

•

for the first time, scan the diskette for viruses.

Advanced Troubleshooting

If you have performed the preceding basic checks but the problem persists, follow these guidelines for troubleshooting specific cases.

After you install your new drive, your computer will not boot, and no error message shows on the screen.

Check your computer manual or BIOS manufacturer to determine

•

whether your BIOS supports drives that have more than 4,096 cylinders. If your system has this limitation, use the following procedure to configure your computer:

1 Turn off your computer, open the case, and remove your new

Seagate drive.

Caution. To avoid electrostatic discharge damage to

your computer or hard drive, make sure you are well-grounded before touching the drive, cable, connector or jumpers.

2 Place a jumper on pins 1 and 2 on the master/slave jumper block as

shown below. This enables the alternate capacity option that causes the drive to appear to your BIOS as having a 2.1-Gbyte capacity.

video card and host adapter. If the computer recognizes the drive when you reboot the computer, turn off the computer. Reinstall the other peripheral cards, one at a time, until the conflict reoccurs. After you have isolated the source of the address conflict, you can resolve the conflict by changing the I/O address of the peripheral that appears to cause the conflict.

If Disk Manager has installed the DDO on your hard drive and you have

•

booted directly from a diskette, the information in the boot record for the drive may not have been loaded. Make sure there is no diskette in Drive A and reboot. If you want to boot from the diskette, follow the “Booting with a Diskette” instructions under “Advanced Disk Manager Options.”

The dealer partitioned and formatted the drive for you in the store, but the drive does not respond when you install it.

Reboot the computer and make sure the drive spins up. Check all cables.

•

Make sure the power supply is adequate for system needs.

•

Make sure the DOS version the dealer used to partition and format the

•

drive is the same version you have installed in your computer. If it isn’t, see your dealer.

Verify the drive-type values in the system setup program. You must install

•

the drive using the same drive-type values your dealer used to partition the drive.

Check for I/O address conflicts between peripheral cards.

•

Check for viruses.

•

The system hangs in FDISK or fails to create or save the partition record.

Check all cables.

•

Your DOS diskette may be corrupted. Try using a backup DOS diskette.

•

Make the partitions smaller.

•

Change the interrupt jumper setting on the host adapter.

•

Some BIOS have a Track 0 protection feature that protects Track 0 from

•

viruses. This may cause FDISK to hang the system. You must disable this feature in the system setup program before you can use FDISK. See your computer reference guide for assistance. Be sure to re-enable this important feature when FDISK is done.

The system error message, “Drive not Ready,” appears.

Check all cable connections. Make sure pin 1 of the drive is connected to

•

pin 1 of the hard-disc controller or host adapter. Make sure the power supply is adequate for system needs.

•

Reboot the computer and make sure the drive spins up.

following problems may have occurred:

– The values may be set with an incorrect translation characteristic. – You may have entered a parameter value that exceeds the physical

capacity of the drive.

– You entered a translation characteristic that does not take advantage of

the drive’s full capacity.

– The drive’s physical specifications exceed the translation limits imposed

by the BIOS.

If your new Seagate® Medalist ®Pro drive will be the only drive in your computer, you do not have to change any jumper settings. In this case, skip ahead to “Attaching Cables and Mounting the Drive.”

If you already have one hard drive in your computer and you are installing a second drive, you must configure one drive as a master and the other as a slave. The master drive will be the “boot” drive (drive C), from which the computer loads system software when it first starts up. To configure your new Seagate drive as the master, slide a jumper onto pins 7 and 8 (see below). To configure the drive as a slave, slide a jumper onto pins 5 and 6 only. The jumper on pins 6 and 8 is a spare and does not affect drive operation. If you need to change the jumpers on your existing hard drive, see the Disk Manager online manual, or contact the drive manufacturer.

SING DISCWIZARD

DiscWizard is a revolutionary new Windows program that makes it easy to install your new Seagate drive. DiscWizard helps you configure your new drive and your computer. It analyzes your system, lets you select various installation options and creates customized step-by-step instructions. It also allows older computers to access the full capacity of your drive.

You can run DiscWizard to install your new hard drive if:

• You already have an existing, bootable hard drive in your computer with at least 3 Mbytes of available disc space

• You are running Windows 3.x or Windows 95.

If you can run DiscWizard, you do not have to read this installation guide. Instead,

ANDLE WITH CARE

Disc drives are extremely fragile. Do not drop or jar your drive.

Keep the drive in its antistatic bag until you are ready to install it.

Always handle the drive by its edges or frame.

Do not apply pressure or attach labels to the circuit board or the top of the drive.

computers also require drive mounting rails, which can be obtained from your distributor or computer manufacturer.

4 Attach a power cable to each drive. If your computer does

not have an unused power connector, you can purchase a Y-shaped power cable from your computer dealer.

5 Check all cable connections and then replace your com-

puter cover. Continue to step 2 below .

ONFIGURING YOUR COMPUTER

Before you format or partition your new drive, you must configure your computer’s BIOS so that the computer can recognize your new drive.

1 Turn your computer on. As your computer starts up, watch

the screen for a message describing how to run the system setup program (sometimes called BIOS or CMOS setup). This is usually done by pressing a special key, such

DELETE, ESC

as manual for details. Press the appropriate key to run the system setup program.

2 Enable LBA mode if it is available. Many BIOS use the logi-

cal block addressing (LBA) mode to access drives with capacities greater than 528 Mbytes.

3 If your BIOS provides automatic drive detection (an

“Auto” drive type), select this option. This allows your computer to configure itself automatically for your new drive.

If your BIOS does not provide automatic drive detection, select “User-defined” drive settings. If your computer supports LBA addressing, enter the LBA cylinder, head and sector values for your drive from the table at the top of the next column. If your computer does not support LBA addressing, enter the CHS values

DDRESSING DRIVE-CAPACITY LIMITATIONS

528-Mbyte limit: The BIOS in some older computers cannot accommodate drives with capacities greater than 528 Mbytes. Seagate provides free Disk Manager software with your drive to overcome this limitation. Alternatively, you can pur chase a hard drive controller or a BIOS upgrade that supports drives with capacities greater than 528 Mbytes.

The 32-bit disk access feature in Windows 3.1 does not work with drives that have capacities greater than 528 Mbytes. If you want to use 32-bit disk access with Windows 3.1, install the Seagate replacement 32-bit access driver, SEG32BIT .386, as described on the back of this sheet.

Drive Partitioning

Partitioning a hard drive divides it into sections (partitions) that function as separate logical drives (labeled C, D, E, etc.).

Because DOS computers cannot access partitions larger than

2.1 Gbytes, you must divide large-capacity hard drives into

Partition-size limit: not access drive partitions larger than 2.147 Gbytes. You can overcome this limitation using the Disk Manager software or the DOS FDISK command to divide your drive into several smaller partitions. Each partition acts as a separate logical drive, with its own drive letter. If most of your files are smaller than 50 Kbytes, you should divide your drive into partitions of 1 Gbyte or less to make the most efficient use of your disc space.

Basic Troubleshooting

If you have installed your drive and it does not function properly, perform the following basic checks:

Verify compatibility. Verify that the host adapter and drive are

•

appropriately matched to each other and to your computer. Refer to the relevant documentation for details.

Check all cards. Verify that all cards are seated in their slots on the

•

motherboard and secured with mounting screws. Check all connectors and cables. Make sure all ribbon and power cables

•

Verify jumper settings. Review the instructions on this sheet and in your

•

host adapter installation guide. Make sure all appropriate jumpers are installed or removed as necessary.

Check your power-supply specifications. Each time you add a new

•

device to your computer, make sure your computer’s internal power supply can support the total power demand. If necessary, consult your dealer for a new power supply.

Verify the drive-type settings in the system setup program. The drive-

•

type settings in the system BIOS must not exceed the physical specifications of your drive. Also, the settings must not exceed the limitations set by the operating system and BIOS.

Check for viruses. Before you use someone else’s diskette in your system

•

for the first time, scan the diskette for viruses.

Advanced Troubleshooting

If you have performed the preceding basic checks but the problem persists, follow these guidelines for troubleshooting specific cases.

After you install your new drive, your computer will not boot, and no error message shows on the screen.

Check your computer manual or BIOS manufacturer to determine

•

whether your BIOS supports drives that have more than 4,096 cylinders. If your system has this limitation, use the following procedure to configure your computer:

1 Turn off your computer, open the case, and remove your new

Seagate drive.

Caution. To avoid electrostatic discharge damage to

your computer or hard drive, make sure you are well-grounded before touching the drive, cable, connector or jumpers.

2 Place a jumper on pins 1 and 2 on the master/slave jumper block as

shown below. This enables the alternate capacity option that causes the drive to appear to your BIOS as having a 2.1-Gbyte capacity.

468

Master/slave jumper block

3 Remount your drive in the computer and replace the computer cover. 4 Insert a bootable DOS diskette into drive A and turn on the computer. It

should boot from drive A and automatically detect the new drive as a

2.1-Gbyte drive.

5 Insert your DiscWizard diskette into drive A and type A:\DM. Then

press

ENTER

. This runs the Disk Manager program.

6 Follow the Disk Manager instructions to install the dynamic drive overlay

and to partition and format your new drive to its full capacity.

7 After Disk Manager is done, reboot your system. You should see the

Disk Manager banner and be able to access the full capacity of your new drive.

The screen remains blank when you power up the system.
