Mounting the drive
------------------
NOTE
Make sure you mount the drive so that you do not strain the cables.
All ST3491 family drives have the same overall dimensions. However,
the positions of the mounting holes are different for metric and
standard drives.
- Standard size drives have an "S" stamped on the frame runner and accept 6-32 UNC screws.
- Metric drives have an "M" stamped on the frame runner and accept M3 screws.
Mount the drive securely in the computer in any orientation using
either the bottom or side mounting holes, as described below.
Position the drive so that you do not strain or crimp the cables.

- Standard size drives have an "S" stamped on the frame runner and accept 6-32 UNC screws.
- Metric drives have an "M" stamped on the frame runner and accept M3 screws. Caution. To prevent drive mounting hole damage, use only the appropriate type of screws as specified. Tighten them gently using no more than 6 inch-lb of torque.
Bottom mounting holes
---------------------
Insert four mounting screws not more than 0.20 inches (6 full turns)
into the drive frame.
Bottom mounting holes. Insert four mounting screws not more than
0.20 inches (6 full turns) into the drive frame.
Side mounting holes. Insert four mounting screws not more than 0.13
inches (4 full turns) into the drive frame.
After you have mounted the drive in the computer, disconnect your
grounded wrist-strap and replace the computer cover.
Side mounting holes
-------------------
Insert four mounting screws not more than 0.13 inches (4 full turns)
into the drive frame.
CAUTION
To prevent damage to the drive:
- Use mounting screws of the correct size and length.
- Gently tighten the mounting screws - do not apply more than 6 inch- lbs of torque.
Storing and shipping your drive
-------------------------------
Keep your original box and packing materials for storing or shipping
your drive. The box has a Seagate Approved Package label. Shipping a
drive in an unapproved container voids the warranty. Call your
authorized Seagate distributor to purchase additional boxes.
Configuring the drive
---------------------
1. Turn the computer off.
2. Remove your computer's cover.
Caution
Special training or tools may be needed to service laptop
computers. Removing the cover may void your warranty. Review
the terms and conditions of your warranty before removing the
cover.
3. Ground yourself. Wear a grounded wrist strap throughout this
procedure, or frequently touch the metal chassis of a computer
that is plugged into a grounded outlet.
4. Remove the drive from its antistatic bag.
5. Install master/slave jumpers.
The master/slave jumper block accepts 2-mm connectors and
jumpers. Use Seagate part number 13211-001 or equivalent.
One-drive system
----------------
Configure the drive for a one-drive system.
Two-drive system
----------------
With two ATA interface drives, you must designate one drive as the
master, or drive 0, and the other drive as the slave, or drive 1.
This can be done in either of two ways: - When using a standard ATA interface cable (that is, you are not using cable select): configure the drive as a master or a slave using the options jumper block as shown in Figure 1 on page 4.
- When using cable select (that is, you have a special cable supporting this drive selection method, and your computer and both drives all support cable select): first install a jumper on pins 3-4 of the options jumper block; then use a drive-select cable to designate master and slave drives.
Attaching cables
----------------
1. Make sure the computer is off.
2. Put on a grounded wrist strap.
3. Connect the remote LED (optional).
4. Attach the power cable. Attach one of the computer power
cables from the power supply of your computer to the 4-pin
power connector on the drive.
5. Attach the interface cable. (Interface ribbon cable length
must be 18 inches or less.) Caution. Connector misalignment
can damage the computer and the drive. Ribbon cables are delicate
- be careful not to crimp or strain them.
One-drive system using a standard ATA 40-pin interface cable:
Connect one end of the cable to the computer's host adapter card
or to the hard drive connector located on the mother-board; connect
the other end to the 40-pin interface connector. Align pin 1 on each
cable connector with pin 1 on its matching equipment connector.
(Cable lead 1 going to connector pin 1 is often denoted by a colored
edge-stripe on the cable; the stripe will lie adjacent to the 4-pin
power connector.)
Two-drive system with a standard ATA 40-pin interface cable: If you
are using a standard 40-pin two-drive ribbon cable, plug one
connector into J1 on each drive and attach the remaining connector
to the host adapter. Align pin 1 on connectors as described above
for a one-drive system.
Two-drive system using interface cable supporting cable select: If
you followed the instructions for two drives and cable-select, you
must assign master and slave status to drives by the following
method: to make a drive the master, attach it to the connector
that has the CSEL signal line connected to pin 28. To make a drive
the slave, attach it to the connector that has pin 28 unconnected
(open). Finally, connect the remaining cable connector to the host
adapter. Note that CSEL is grounded on the host adapter.
CAUTION
If you attach the interface cable incorrectly, you could damage the
computer and the drive.
If you are installing two drives, use a daisy-chain ribbon cable. The
ribbon cable should not be longer than 18 inches (0.457 meters).
Ribbon cables are delicate - be careful not to crimp or strain them.

Read before you begin
---------------------
Application.
Your Seagate drive is designed for IBM AT and compatible personal
computers. It uses the ATA interface. Warning. Turn off the
computer before you open the case, touch any internal components
or install the drive.
Static discharge
----------------
Observe these precautions to avoid static electricity, which can
damage a drive or computer. Static electricity can be generated
by wool or synthetic clothing, carpets and plastics of any kind
including most bags.
- Keep the drive in its static-shielded bag until you are ready to install it. Do not attach any cables to the drive while it is in its static-shielded bag.
- Before you handle the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal chassis of a computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the installation procedure.
- Handle the drive gently and only by its edges or frame. Until you are ready to install it, place it only on an antistatic surface.
- Do not touch the drive's connector pins or its printed circuit board. Drive handling. The drive is extremely fragile_handle it with care. Do not attach labels to any part of the drive.
Inspection
----------
After you are familiar with the handling precautions listed above,
inspect the drive. If it appears to be damaged, call your
distributor or dealer immediately.
Warranty. See your authorized Seagate distributor or dealer.
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 facilities authorized
to repair Seagate drives. Seagate does not sanction any third-party
repair facilities.
Configuring the computer
------------------------
1. Turn the computer on.
2. Enter the System Setup routine (also known as CMOS Setup) and
define the new drive's translation geometry as follows: 2A.
Select the drive type according to the following guidelines:
Select a drive type matching your drive's translation geometry.
If none of the standard drive types offered by the System Setup
routine match the translation geometry shown in the following
table, select the user-defined or custom drive type to enter
your drive's translation geometry.
If your System Setup routine does not offer a user-defined drive
type, select a standard drive type with a capacity that approximates,
but does not exceed, your drive's capacity of the table).
If you do not know what drive types your System Setup routine
supports, download the FindType utility from the Seagate BBS to
assist you in choosing an appropriate drive type.
Low-level formatting
--------------------
AT drives are low-level formatted at the factory to 512 bytes per
sector. You do not need to low-level format AT drives.
Partitioning
------------
You must partition a drive into one or more logical drives before
you can use it. If you are using DOS Version 3.3 or earlier, disc
partitions are limited to about 33 Mbytes. Beginning with DOS
Version 4.0, you can put the entire drive on one partition.
Caution. Partitioning or formatting a drive at any level erases
all data on it. Before you repartition or reformat your drive,
save all existing files to backup files. Seagate assumes no
liability if you erase your data.
You can partition a drive as follows:
1. Put a bootable DOS diskette in the A drive and boot the computer.
This loads DOS from the floppy and runs it.
2. At the DOS prompt, type FDISK and then press ENTER to run the
FDISK utility.
3. Select create DOS partition or logical DOS drive and press ENTER.
4. Select create primary DOS partition. Use the maximum available
size for your primary partition and make the partition active.
This puts the entire drive on one partition and allows the
computer to boot (load DOS) from the partition. Press ENTER
after every selection.
5. After you make all the appropriate selections, the computer
automatically reboots itself.
Many Unix-based operating systems allow you to partition the drive
for DOS applications. See your operating system manual for details.
High-level formatting
---------------------
High-level formatting verifies the information written by the low-
level format and builds the file allocation table (FAT) used by DOS
to access files on the drive. Use the DOS FORMAT utility to high-
level format the drive as follows:
1. Type the following command line at the DOS prompt: format drive:
/V /S drive: designates the drive you are formatting. Use c: if
you are formatting the boot drive or if your system contains
only one hard drive. To format a non-boot drive, type d:
instead. /V tells the computer you want to label the drive
after it is formatted. Labeling the drive can prevent someone
from accidentally deleting the partition and losing your data.
/S tells the computer to make the drive bootable and copy the
necessary system files to the drive.
2. When the computer prompts you for a volume label, type any valid
name you want to designate the drive. In Unix, high-level
formatting creates the i-node used for file access information.
Drive formatting and partitioning are both performed by a single
operating system utility. Refer to your Unix operating system
documentation for instructions.
