The drive will operate in all axis (6 directions).
Mounting the drive
------------------
You may mount (and operate) the ST9100A and ST9100AG in any
orientation. However, you must securely attach the drive to
a rigid frame using four side-mounting screws or four bottom-mounting
screws.
Caution. To avoid damaging the drive:
- Use M3X0.5 metric mounting screws only.
- Do not insert mounting screws more than 0.150 inches (3.81 mm) into the mounting holes.
- Do not overtighten the screws (maximum torque: 3 inch-lb).
Allow a minimum clearance of 0.030 inches (0.762 mm) around the
entire perimeter of the drive for cooling airflow.
Most 9100A/AG drives conform to the industry-standard MCC mounting
specification. Refer to the ST9100A and ST9100AG Product Manual
(Seagate Publication 36211-001) for details.
Installation overview
---------------------
Drive installation can be divided into several logical steps:
1. Setting master/slave jumpers
2. Connecting cables
3. Mounting the drive in the system
4. Configuring system BIOS
5. Formatting and partitioning the drive
Connecting cables
-----------------
ST9100A and ST9100AG drives use a 44-pin AT interface connector
cable with two rows of 22 female contacts on 0.079-inch (2 mm)
centers.
Most cables have a stripe down one side, which designates pin 1. Make
sure pin 1 on the interface cable connector is aligned to pin 1 on
the drive interface connector and pin 1 on the host connector. To
assist in cable alignment, pin 20 has been removed on the male
interface connector on the drive. This type of connector is designed
to be used with a keyed cable connector having a plug in place of pin
20.
Before mounting the drive, be sure that the connecting cable is long
enough to reach the drive, but not so long that it will be pinched
when the system enclosure is replaced. Connecting cables for the
ST9100A and ST9100AG must be no longer than 18 inches (457 mm).
Power connections
-----------------
Power for the ST9100A and ST9100AG is supplied through the 44-pin
interface connector.
Caution. These drives can accept only +5 volts DC power. Do not use +12 volts DC power.
Features
SEAGATE ST9100A/AG INSTALLATION MANUAL
Read before you begin
---------------------
Note. ST9100A and ST9100AG are usually installed in notebook or
laptop systems. Special training or tools may be needed to service
these computers. In some instances, opening the case may void your
warranty. Be sure to review the terms and conditions of your system
warranty before opening the system enclosure.
Warning. To avoid personal injury and damage to the electronic
devices, always power off and unplug your computer system before
touching any internal components.
Observe static discharge precautions ------------------------------------ - Keep the drive in its static-shielded bag until you are ready to complete the installation.
- Do not touch the PC board or the I/O connector pins.
- Always handle the drive by its edges or frame. Never apply pressure to the PC Board or to the drive top cover.
- Use a grounded wrist strap. If none is available, ground yourself by touching the metal chassis of the system before handling any components.
- Use antistatic padding on all work surfaces and avoid static- inducing carpeted areas.
Check all items. Examine the drive, cables, mounting hardware
and accessories, documentation and packaging. If any item is
incorrect, missing or appears damaged, contact your distributor
or dealer immediately.
Handle drives carefully. Improper handling during transit or shipping
accounts for many installation problems. Even minor bumps can exert
relatively large G forces on these drives. Always handle the drive
carefully. In addition, do not attach any labels to the drive top
cover, as they may prevent proper ventilation.
Maintenance and Repair
----------------------
Seagate drives do not require 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 Seagate drives.
Seagate does not sanction any third-party repair facilities.
Shipping. When transporting or shipping a drive, you must use a
Seagate-approved container. If possible, use an original Seagate
shipping box with a Seagate Approved Package label. Shipping a
drive in a nonapproved container voids the drive warranty.
Seagate service centers may refuse receipt of components improperly
packaged or obviously damaged in transit. Call your authorized
Seagate distributor to purchase additional boxes.
Seagate recommends shipping by an airride carrier experienced
in handling computer equipment.
Configuring system BIOS
-----------------------
Before the host system can recognize a new drive, it must be provided
with basic information about the drive into the host system BIOS.
Specifically, you need to know the number of cylinders, heads, and
sectors, as well as the overall capacity of the drive you are
installing. It is not necessary to understand these terms to set up
the system BIOS.
Read your system documentation or run your system setup program
to determine which drive types your BIOS supports. Another method is
to run the FINDTYPE.EXE utility program, available from Seagate
Technical Support services (on the SeaBOARD BBS).
The methods used to configure system BIOS vary from system to system.
In many cases, you can run a setup program from the DOS prompt. In
other cases, you must initiate BIOS setup by pressing certain keys
while the system is booting up.
Within the setup program, there are three possible ways that you
can specify your drive type:
- Match your drive specifications with those of a drive type specified in the setup program.
- Specify a custom or user-defined drive type in the setup program, then manually enter your drive specifications.
- Select specifications lower than those required for your drive, and allow your drive to mimic the drive type selected.
Drive Specification ST9100A and ST9100AG
No. cylinders 748
No. read/write heads 14
No. sectors per track 16
Total No. sectors 167,552
Capacity (Mbytes) BIOS calculated 81.8 - Usable 85.8
When the drive specifications are entered manually as a userdefined
or custom drive type, the BIOS should display a drive capacity equal
to the BIOS calculated capacity in the table above.
This value will be lower than the usable drive capacity.
In a few situations, none of the drive types specified in your BIOS
setup program will match your drive, and the setup program will
not provide an opportunity to specify a custom drive type. In this
case, consider the third option - allowing your ST9100A or ST9100AG
drive to mimic one of the BIOS-supported drive types. During the BIOS
setup process, simply select a drive type with a capacity that is
less than or equal to the drive's BIOS calculated capacity. This
drive type should have no more than 1,024 cylinders, 16 read/write
heads, or 63 sectors per track. In addition, the total number of
sectors for that drive type (listed in the setup program) should not
exceed the number of cylinders times the number of read/write
heads times the number of sectors per track. In other words:
Total sectors per drive ?
(No. cylinders) ??
(No. read/write heads) ??
(No. sectors/track) BIOS compatibility recommendations
The ST9100A and ST9100AG are AT interface compatible drives, which
conform to ATA specifications. The host system BIOS must provide
support for the AT interface command set. Consult the system
documentation for information on the AT interface within your system.
Several key compatibility issues are discussed below.
In accordance with ATA specifications, the BIOS must reset any
emulation/translation parameters after a hard reset is received
from the host.
In some configurations, the ST9100A and ST9100AG drives supply 16
bytes of Error Correction Code (ECC) with the Read Long and Write
Long commands. Depending on the drive type, your system BIOS may look
for 4 bytes of ECC. If your system BIOS expects 4 bytes of ECC and
the drive supplies 16 bytes, some drive diagnostic programs may fail,
typically resulting in timeout errors. Consult your system
documentation or call your system dealer or manufacturer for
information on configuring your system to receive 4 bytes of ECC.
Formatting and Partitioning the drive
-------------------------------------
Caution. Reformatting or repartitioning a drive that contains
data may result in a partial or complete loss of that data. Make sure
all data has been safely backed up before repartitioning or
reformatting a drive. Seagate Technology assumes no liability for
lost data.
Low-level formatting
--------------------
Seagate AT Interface drives are low-level formatted at the factory
and do not require additional low-level formatting prior to use.
Partitioning
------------
A single disc drive can be subdivided into partitions that behave
as separate drives (labeled C, D, E, etc.). Versions of DOS prior
to Version 4.0 are not able to access more than 32 Mbytes of disc
space as a single drive. Therefore, drives having a capacity of
over 32 Mbytes must be divided into several smaller partitions
for use with these older versions of DOS. Seagate does not
recommend using the ST9100A or ST9100AG with a DOS version prior to
Version 3.3.
To partition a drive, you must first boot the system using a floppy
disk that contains system files. Partition the drive using the DOS
FDISK utility program (described in your DOS manual). If you are
partitioning a drive that will be used to boot the system, make
sure that the primary DOS partition is marked active.
High-level Formatting
---------------------
Once the drive is partitioned, use the DOS FORMAT command (or
equivalent utility program) to high-level format each of the
drive partitions. This process verifies the information written by
the low-level format and creates file allocation tables (used to
catalog and access files). Consult your DOS manual for FORMAT
command options. During formatting, DOS system files should
be transferred to one disc partition (generally the "C" drive), so
that the system can boot off of that drive. After high-level
formatting a drive, you can verify the usable drive capacity using
the DOS CHKDSK utility program.

Installation troubleshooting
----------------------------
Before calling Seagate Technical Support, please read and consider
all the possibilities discussed below. The suggestions presented
here will resolve the vast majority of installation problems.
Warning. To avoid personal injury and damage to electronic
components, always power off and unplug the computer system before
changing jumpers or touching any internal components.
- 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.
- Verify your configuration. Refer to the drive and controller installation guides to make sure all jumper settings suit your configuration requirements.
- Check all cables. Make sure all cables are securely connected. Ribbon cables are especially fragile. Make sure they are not crimped or damaged in any way. Having extra cables on hand for troubleshooting saves time and frustration. Most cables have a stripe down one side to designate the pin 1 location. Make sure pin 1 on the interface cable connector is connected to pin 1 on the drive interface connector and pin 1 on the host connector.
- Check all cards. Make sure all cards are secured 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. After the cards are permanently installed and the system is running properly, use mounting screws to secure the cards in place.
- Check the power supply specifications. The output of your power supply may not be sufficient to meet the power requirements of the new devices you have installed. 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. You must use the same version of DOS throughout all phases of building and configuring your system.
- Verify the BIOS drive type. The BIOS drive type you specified during system setup must approximate, but not exceed, the specifications and maximum drive capacity of the drive.
Refer to the BIOS configuration section of this manual to double check your drive specifications against those specified in your system BIOS.
- 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 lockups, reboots and drive errors.
