Verify that the system power is off before attempting any instal-
lation.
Static discharge. Observe the precautions listed below.
e Keep the drive in its static-shielded bag until you are ready to
complete the installation.
e Handle the drive by its edges or frame.
e Do not touch the I/O connector pins. Do not apply pressure,
_ or attach labels, to the circuit board or the drive top cover.
e Use a grounded wrist strap at your workstation. If you do not
have one, ground yourself frequently by touching the metal
chassis of the system before handling any components. The
system must be plugged into an outlet that is connected to. an
earth ground.
e Use anti static padding on all work surfaces.
e Avoid static-inducing carpeted areas.
Inspection. Examine the drive, cables, mounting hardware,
accessories, documentation, and packaging. If any item is miss-
ing or damaged, call your distributor or dealer immediately.
Warranty. See your authorized Seagate distributor or dealer.
Maintenance and repair. Seagate drives do not need any
preventive maintenance. The head/disc assembly is sealed and
does not contain any user-serviceable components. Tampering
with the factory seal voids the warranty. Seagate customer
service centers are the only facilities authorized to service Sea-
gate drives. Seagate does not sanction any third-party repair
facilities.
Caution. If you intend to install this drive in a laptop system,
check the conditions of the system warranty first. These systems
should only be serviced by trained technicians.

Ps 3 ST3144 Family Installation Guide, Rev. D
Shipping. When transporting or shipping a drive, you must use
a Seagate-approved container. Keep your original box; it has a
Seagate Approved Package label. Shipping a drive in a non-ap-
proved container voids the warranty. Call your authorized Sea-
gate distributor to purchase additional boxes.

Overview
Installation of the drive can be divided into distinct steps as
outlined below. Some of these may not be applicable to your
particular installation requirements. Refer to the drive installation
section for specific information on your drive model.
e Drive jumper settings. Select the appropriate drive features
by installing or removing jumpers on the jumper blocks on the
drive circuit board.
e CMOS configuration. Basic information about the drive must
be entered into the host system CMOS so that it may properly
access the drive for reading and writing data. The number of
heads, cylinders, and sectors per track are specific to each
drive and collectively define the drive’s geometry.
e Low-level formatting. Seagate AT interface drives are low-
level formatted at the factory and do not need low-level format-
ting.
e Partitioning. A drive can be divided into partitions that behave
as individual drives within the system. Versions of DOS earlier
than 4.0 limit the maximum drive capacity and consequently
require higher capacity drives to be divided into smaller parti-
tions. For DOS users, each partition is assigned a different
letter, for example, C: and D: for a drive with two partitions.
Use the DOS FDISK utility to partition the drive. After the drive
has been defined in CMOS, you must boot the system to the
floppy drive with a bootable DOS diskette. Then run the FDISK
utility to partition the drive. Refer to your DOS manual for using
FDISK. Use DOS 3.3 or higher.
Caution. If you partition or format a drive at any level, you
erase all your data. Backup the drive first. Seagate assumes
no liability for lost user data.
ST3144 Family Installation Guide, Rev. D a
e High-level formatting. This procedure verifies the informa-
tion written by the low-level format and establishes drive
access information used by the system. High-level formatting
also creates the File Allocation Table (FAT) used by DOS for
drive access. The high-level format is initiated by the FORMAT
command. Refer to your DOS manual for instructions on using
the FORMAT command.
$T3144 family drives
This guide provides installation information for the ST3096A,
ST3120A, and ST3144A drives. All drives in this family automat-
ically park their heads at power-down.

AT interface setup
This section describes drive geometries, compatible BIOS revi-
sions, jumper settings, and installation procedures for ST3144
family drives.
AT drive geometries
The following table shows the recommended drive geometries
for ST3144 family drives.
aud na aree
Model Formatted Cyl.
MBytes peas Track
ST3096A| 89.1 1,024 | 10 85.0
ST3120A| 106.9 | 1,024 | 12 102.0
ST3144A| 130.7. | 1,001 | 15 17 124.6
Use a system utility, usually called SETUP, to enter the drive
geometry into the system CMOS. If the drive types offered by the
CMOS do not support the number of heads, cylinders, and
sectors/track shown by the table, and your system does not
support a “user-defined” drive type, select a drive type in your
system CMOS with a capacity less than or equal to the capacity
given in the “Formatted CMOS Megabytes” column of the table
above.
Note. The number of Heads times the number of Sectors cannot
exceed 255, as given by the following equation:
(Heads) x (Sectors) < 255
When you enter the drive geometry using the “user-defined” or
“custom” drive type, the CMOS calculates the drive capacity. This
capacity is listed in the “Formatted CMOS Megabytes” column of
the table. It is the same effective capacity as the capacity shown
in the “Formatted Megabytes” column, even though the CMOS
value is lower. After high-level formatting, you can check the drive

capacity using the DOS CHKDSK utility. If you do not know what
drive types your CMOS supports, use the FINDTYPE utility from
the Seagate Technical Support BBS to assist you in choosing an.
appropriate drive type. See Page 2.
Compatible BIOS revisions
ST3144 family drives are compatible with the BIOS revisions
listed in the table below. To find out which BIOS your system —
uses, reboot the system. The BIOS manufacturer, version, and
date are displayed on the monitor.
Typically, BIOS compatibility problems include intermittent drive
) access errors or system time-out errors. If you have compatibility
problems, call your system dealer or manufacturer.

Configuring and installing the drive
1. Turn off the system power.
2. Wear a grounded wrist strap. If you are grounding yourself
to the chassis of the host computer, the power cord must be
plugged into an electrical outlet that has an earth ground.

3. Master/Slave configuration. The table below defines jumper
settings for configuring up to two drives on a single AT bus.
Refer to Figure 1 for jumper locations.
System Configuration
| Slave Present
Installed Removed
Only drive in system
Drive 1 in a two-drive system | Installed Installed
Removed
Drive 2 in a two-drive system | Removed
4. Drive Activity LED jumper. If you install a jumper on pins 9
and 10 of the User Configuration jumper block, the drive
indicates activity to the system through a connector on the host
adapter or motherboard. ;
5. Attach the 40-pin AT interface cabie. A dual-drive system
requires a 40-pin AT interface daisy-chain cable. Pin 20 has
been removed on the connector for keying purposes.
Most interface cables have a stripe on one side to designate
Pin 1. Make sure Pin 1 on the cable connector is aligned to Pin
1 on the drive connector and Pin 1 on the host connector. The
maximum cable length is 18 inches (457 mm).
For systems without an embedded AT interface connector on
the motherboard, Seagate offers the STO7A/STO8A AT inter-
face host adapters.
Note. To prevent improper pin alignment during installation, it
is recommended that the mating cable connector be keyed, by
inserting a plug into the Pin-20 location of the cable connector.
6. Attach a system power cable to the drive power connec-
tor. The ST3144 family drives have both 3-pin and 4-pin power
connectors.
7. Mount the drive in the host system chassis.

Mounting the drive
You can mount the drive in any orientation, provided you do not
mount it more than 5° from a vertical or horizontal axis. For best
results, format the drive in its final mounting orientation.
Bottom mounting. Insert four mounting screws not more than
0.20 inches (6 full turns) into the drive frame. If you use a screw
that is too long, you could damage the drive.
Side mounting. Insert four mounting screws not more than
0.13 inches (4 full turns) into the drive frame. If you use a screw
that is too long, you could damage the drive.
Screw sizes: Use 6-32 UNC screws on drives with standard-size
mounting holes. These drives have an “S” stamped on the frame
runner. Use M4 screws on drives with metric mounting holes.
These drives have an “M” stamped on the frame runner.
Caution. Be careful not to over-tighten screws. You could dam-
age the drive. (Max torque: 6 inch-lbs)
Formatting the drive
Seagate AT Interface drives are low-level formatted at the factory
and do not need low-level formatting. Partition the drive using the
DOS FDISK utility. Then, high-level format the drive using the
DOS FORMAT utility. Use DOS 3.3 or higher. Consult your DOS
manual for FORMAT and FDISK command syntax. If the drive is
to be made bootable, copy the system files onto it and mark the
primary DOS partition active.
Caution. If you partition or format a drive at any level, you erase
all your data. Backup the drive first. Seagate assumes no liability
for lost user data.
$13144 Family Installation Guide, Rev. D 11
Frame kit and remote LED
To install this 3.5-inch drive in a 5.25-inch frame, use a Seagate
frame kit, part number 54459-016. This frame kit can only be used
with drives that have standard-size mounting holes. These drives
have an “S” stamped on each frame runner. If your drive has an
“M” (for metric) stamped on each frame runner, do not attempt
to mount it in this frame kit.) The frame kit contains a remote LED.
Installation trouble-shooting
Before you begin trouble-shooting, read and be aware of all the
considerations discussed in this section. The suggestions pre-
sented here resolve the vast majority of installation problems.
Warning. Always power down the system before changing
jumper settings or unplugging cables and cards.
e Verify compatibility. Check the documentation for the host
adapter and the drive to confirm that these components are
appropriately matched for each other and to your system.
e Verify your configuration. Refer to the drive and controller
installation guides to make sure all jumper settings suit your
configuration requirements.
e Check all cables. Make sure all cables are securely con-
nected. Ribbon cables are especially fragile. Make sure they
are not crimped or damaged in any way. Having extra cables
on hand for trouble-shooting saves time and frustration.
Note. Most cables have a stripe on one side to designate the
Pin 1 location. Make sure Pin 1 on the interface cable connec-
tor is connected to Pin 1 on the drive interface connector and
Pin 1 on the host connector. Refer to Figure 1 for the location
of Pin 1 on the drive interface connector.

12 ST3144 Family Installation Guide, Rev. D
Check all cards. Make sure all cards are securely seated in
the expansion slots on the motherboard. Full size (16-bit)
cards cannot be plugged into half-size (8-bit) slots. Make sure
all cards are plugged into appropriately sized expansion slots.
Once the cards are permanently installed, and the system is
running properly, use mounting screws to secure them in
place.
Check the power supply specifications. The output of your
power supply may not meet the power requirements of the new
devices you are installing. If you are not sure whether the
power supply meets the system requirements, consult your
system dealer or distributor.
Use the same version of DOS throughout your system.
The same version of DOS must be used throughout all phases
of building and configuring your system.
Verify the CMOS drive type. The CMOS drive type must
approximate, but not exceed, the physical specifications and
maximum drive capacity of the disc drive. Refer to the Default -
Drive Geometry section of this installation guide for drive
specifications and CMOS configuration information.
Check for viruses. Before installing any new software, scan
the installation diskettes for viruses. After the software has
been installed on the hard disc, scan that drive for viruses.
Symptoms of viruses can include intermittent system lock-ups,
re-boots, drive errors, etc.
