Read before you begin
Application. Your drive is designed for IBM AT and compatible
personal computers, particularly laptop and notebook models.
Warning. Turn off the computer (and, if you have a notebook or
laptop computer, remove the battery) before you open
the case or touch any internal components.
Caution. Special training or tools may be needed to service
laptop and notebook computers. Opening the case
may void your warranty. Review the terms and conditions of your warranty before opening the case.
Static discharge. Observe the following precautions:
• Before handling any components, put on a grounded wrist strap.
• Use antistatic padding on all work surfaces.
• Avoid static-inducing carpeted areas.
• Keep the drive in its static-shielded bag until you are ready to
complete the installation. Do not attach any cables to the drive
while it is in its static-shielded bag.
• Handle the drive by its edges or frame.
• Do not touch the I/O connector pins or the 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.

you void 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 drive
1. Put on a grounded wrist strap. Wear the grounded wrist
strap throughout the installation procedure.
2. Install master/slave jumpers. In a two-drive system, you
need to designate one drive as the master, or drive 0, and
the other drive as the slave, or drive 1. To do this, install the
master/slave jumpers as shown in Figure 1. In a one-drive
system, configure the drive as a master (no jumpers installed).
Alternatively, you can configure the drive as a master or
slave using the cable select option. This requires a special
daisy-chain cable that grounds pin 28 (CSEL) on one of its
two drive connectors. If you attach the drive to the grounded
CSEL connector, it becomes a master. If you attach the
drive to the ungrounded CSEL connector, it becomes a
slave. To use this option, the host system and both drives
must support cable select.
To configure an ST9300 family drive for cable select, install
both master/slave jumpers.
Attaching cables
This drive is designed for a host computer that supplies
interface signals and +5V power through a single 44-pin
connector and cable. If your computer has a fixed connector
that attaches directly to the drive, skip ahead to the following

section, “Mounting the drive.” Otherwise, perform the following
steps:
1. Turn off the computer and remove the battery.
2. Put on a grounded wrist strap.
3. Open the case of your computer. See your system manual
for instructions.
Caution. Opening the case may void your computer’s warranty.
4. Connect the 44-pin interface/power cable. Match pin 1 of
the cable to pin 1 of the interface connectors on the drive and
on the computer. Pin 1 is usually denoted by a stripe along
one edge of the cable. The location of pin 1 on the drive
interface connector is shown in Figure 1 on page 3. The cable
should be no longer than 18 inches (0.457 meters).
Caution. The printed circuit cables used in some laptop com-
puters are delicate. Be careful not to tear them.
Mounting the drive
Mount the drive securely in the computer using M3X0.5 metric
screws in the four bottom mounting holes or the four side
mounting holes. You can mount the drive in any orientation. Be
careful not to strain or crimp the interface/power cable.
Caution. To prevent damage to the drive:
• Be careful not to bend the drive connector pins, especially
when plugging the drive into a fixed connector.
• Use mounting screws of the correct size and length.
• Gently tighten the mounting screws—do not apply more than
3 inch-pounds of torque.
• Do not insert mounting screws more than 0.15 inch.
ST9300 Family Installation Guide, Rev. A 5
Note. This drive meets industry-standard MCC mounting speci-
fications. When installing this drive in a fixed-mounting
application, you must use MCC-compatible connectors
and mounting hardware. If the mounting holes in your
computer do not line up with the mounting holes on the
drive, your computer may not be MCC-compatible.
Configuring your computer
Before your computer can recognize a new drive, you must enter
basic information about the drive into the computer’s long-term
memory (usually a battery-powered CMOS chip). The computer’s basic input/output system (BIOS) uses this information to
control the flow of data to and from the drive.
Note. Some newer computers can automatically determine your
drive type and configure themselves appropriately at startup.
Read your system manual to determine whether this applies
to your computer. If so, then skip ahead to the following
section, “Formatting and partitioning the drive,” on page 7.
In most computers, you must enter the number of cylinders,
heads and sectors using the system setup program (see page
6). The table below lists data for the ST9300 family drives.
Drive specification ST9300AG ST9240AG ST9150AG
No. cylinders 569 988 419

To configure your system BIOS, follow these steps:
1. Turn on your computer.
2. Run the system setup program. This program configures
the system BIOS to recognize your drive. In some computers
you run the system setup program by pressing special keys
while the computer is booting up. In other computers, you can
run the program from the DOS prompt. See your system
documentation for more information.
3. Enter your drive specifications. Within the system setup
program, there are three possible ways that you can enter
your drive’s specifications. These are listed below in order of
increasing complexity.
• Select a predefined drive type. Most system setup pro-
grams provide a long list of predefined drive types. Select a
drive type with specifications that match those of your drive
(refer to the table on page 5).
• Specify a
system setup program doesn’t list a predefined drive type
that matches your drive specifications, you may be able to
define a custom or user-defined drive type. You can then
enter your drive specifications (from the table on page 5).
When you enter drive specifications for a custom or userdefined drive type, the setup program should display a
drive capacity less than or equal to the
capacity
than the usable drive capacity.
• Allow your drive to emulate or
predefined drive types. If none of the predefined drive
types exactly matches your drive, and your system setup
program does not allow you to specify a custom drive type,
custom
or
user-defined
drive type. If the

your drive may be able to emulate one of the predefined
drive types.
Select a predefined drive type that meets all of the following
requirements:
•

•
Read/write heads
•
Sectors per track
•
Total sectors per drive

≤
*
(cylinders) × (read/write heads) × (sectors per track)*
* Drive-specific values for drive capacity, cylinders,
read/write heads and sectors per track are listed in the
table on page 5.
If you are not sure which drive type to select, try running
the FINDTYPE.EXE utility program. This program is available from Seagate’s Technical Support services (on the
SeaBOARD computer bulletin board).
Caution. Write down the drive type that you have selected and
any drive specifications that you have entered (use the
Notes page at the end of this manual). Keep this
information in a safe place. You will need it to retrieve
data from the drive if your CMOS battery fails.
Formatting and partitioning the drive
Caution. Formatting or partitioning a drive that contains data
destroys 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.
8 ST9300 Family Installation Guide, Rev. A
Low-level formatting
Seagate AT Interface drives are low-level formatted at the factory
and do not require additional low-level formatting before use.
Partitioning
The partitioning process subdivides a single disc drive into
partitions that behave as separate logical drives (labeled C, D,
E, etc.). You can also set up the entire disc as a single partition.
Note. If you are using a version of DOS prior to Version 4.0, the
operating system cannot access more than 32 Mbytes in
a single partition. Therefore, you must divide a drive with
a capacity of over 32 Mbytes into several smaller partitions. We do not recommend using ST9300 family drives
with DOS versions prior to Version 3.3.
1. Restart your computer. Boot up the computer using a
diskette that contains DOS system files.
2. Run the FDISK program. Insert a DOS program diskette
containing the FDISK program into your diskette drive. At the
DOS prompt, type FDISK, press
tions on the screen to create one or more partitions. See your
DOS manual for details. If you are partitioning a drive that will
be used to boot the computer, make sure that the primary
partition is marked active.
ENTER, then follow the direc-
High-level formatting
High-level formatting verifies the information written by the lowlevel format and creates file allocation tables used to catalog and
access files.
1. Run the FORMAT program. Insert a DOS program diskette
containing the FORMAT program into your diskette drive. At
the DOS prompt, type FORMAT, followed by the drive letter
ST9300 Family Installation Guide, Rev. A 9
for the first drive partition (for example, FORMAT C:); then
press
ENTER. Repeat this procedure to format each of the new
drive partitions you have created. Consult your DOS manual
for FORMAT command options.
Note. If you are formatting the drive partition that will be used to
boot your computer (the “C” drive), copy the DOS system
files to this drive. To do this, type /s after the format
command (for example, FORMAT C: /s)
2. Verify the drive capacity. After high-level formatting a drive,
you can verify the usable drive capacity by running 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 address the vast majority of installation problems.
General troubleshooting procedures
The following is a list of general troubleshooting procedures.
Solutions for specific problems are provided on subsequent
pages.
Warning. Always turn off the computer before changing jump-
ers, moving cables or touching any internal components.
• Verify hardware compatibility. Check the documentation
for your drive, host adapter and computer to confirm that these
components are compatible.
• Verify your hardware configuration. Check the documen-
tation for your drive, host adapter and computer to confirm
that all jumpers are set appropriately.
10 ST9300 Family Installation Guide, Rev. A
• Check all cables. Make sure that all cables are securely
connected. Printed circuit and ribbon cables are quite fragile.
Check to see that they are not crimped or damaged. Make
sure that pin 1 of the interface cable is connected to pin 1 of
the interface connector on the drive and on the computer.
Most ribbon cables have a stripe down one side to designate
pin 1. The location of pin 1 on the drive interface connector is
shown in Figure 1 on page 3.
• Check all cards. If your computer has expansion cards,
check to see that they are inserted completely into their slots
on the motherboard and are secured with appropriate mounting screws. Make sure that full-size (16-bit) cards are not
plugged into half-size (8-bit) slots.
• Verify the BIOS drive type. Make sure that you entered the
correct drive type or translation geometry in the BIOS setup
program. The drive capacity and number of sectors specified
in the BIOS must not exceed the specifications shown in the
table on page 5. If the drive type is incorrect, you must rerun
the system setup program. Then partition and high-level
format the drive again.
• Check for I/O address conflicts. To isolate an address
conflict, first verify that the drive and host adapter are compatible with your system by disconnecting all other peripherals
except the video card. Then install the drive and host adapter,
and test the system. Next, install the other peripherals, one at
a time, until the conflict reappears. After you have isolated the
source of the address conflicts, you can resolve the conflict
by changing the I/O address of the peripheral that appears to
cause the conflict.
• Check the power supply. The output of your power supply
may not be sufficient to meet the power requirements of the
ST9300 Family Installation Guide, Rev. A 11
new devices you have installed. If you are not sure whether
your power supply meets your system requirements, consult
your computer dealer or distributor.
• Check your DOS version. You must use the same version
of DOS throughout all phases of building and configuring your
computer system.
• Check for viruses.
checking program to scan your computer’s memory, hard
discs and any suspect diskettes for viruses. Run the viruschecking program if you encounter inexplicable disc errors or
damage to disc partitions. Also, before installing any new
software, scan the installation diskettes for viruses.
Use the latest version of a reliable virus-
Specific Troubleshooting Procedures
Methods for resolving specific drive installation problems are
listed on the following pages. These methods incorporate many
of the general troubleshooting techniques described in the previous section.
The screen remains blank when you power up the computer.
• Make sure the monitor is plugged in and turned on.
• Check all cards. Make sure the video card is seated in its slot
and secured with mounting screws.
• Check all cables. Make sure the video card cables (if any) are
securely attached.
• Power down the computer and remove the drive host adapter.
If the screen comes on after you reboot, the host adapter may
be incompatible or defective. If so, see your dealer.
12 ST9300 Family Installation Guide, Rev. A
At startup, the computer does not recognize the presence
of the drive.
• Check all cables.
• Check jumper settings on all drives.
• Check the power supply.
• Reboot the computer and make sure the drive spins up. If your
drive is very quiet, you may not be able to hear it spin up. In
this case, check the drive activity LED if your computer has
one. If the drive does not spin up, check the drive cables again.
• Verify the BIOS drive type.
• Check for I/O address conflicts.
• Try a warm boot. Press
CTRL, ALT and DELETE simultaneously
to reboot the computer without turning off the power. If a warm
boot causes a previously unrecognized drive to become recognized, there may be a timing problem in which the drive fails
to become ready before the host completes its power-on
self-test.
One possible solution is to power up your computer with its
processor set at low speed (see your computer manual for
details on setting processor speed). After the computer is up
and running, return your processor to high speed or turbo
mode. Another option is to warm-boot your computer after
every power-on. You may also be able to solve this problem
by upgrading your system BIOS.
The dealer partitioned and high-level formatted the drive for
you in the store. Later, you installed the drive and it does
not work.
• Reboot the computer and make sure the drive spins up.
• Check all cables.
ST9300 Family Installation Guide, Rev. A 13
• Check the power supply.
• Check your DOS version. Call your dealer to make sure the
DOS version the dealer used to partition and high-level format
the drive is the same as the version you have installed on your
computer.
• Verify the BIOS drive type. When you run the system setup
program on your computer, you must specify the same BIOS
drive type or translation geometry that the dealer used.
• Check for memory conflicts.
• Check for viruses.
During the FDISK program, you get an error message warning of an attempt to write to track 0 or to the boot sector; the
message may also suggest that a virus is present.
• This occurs in systems having a virus-protection scheme that
does not allow programs to modify the boot sector of the disc.
See your system manual for details. To avoid the problem, run
the system setup program and turn off the virus-protection option.
Then exit system setup and run the FDISK and FORMAT
programs. After all drive partitions are formatted, use the system
setup program to turn virus protection on again.
During the FDISK program, the computer hangs or fails to
create or save the partition record.
• Check all cables.
• The FDISK program on your DOS utilities diskette may be
corrupted. Try running the program from a different diskette.
• If you are using a version of DOS prior to Version 4.0, make
the drive partitions smaller than 32 Mbytes.
14 ST9300 Family Installation Guide, Rev. A
• Try another drive type or translation geometry. Sometimes the
host BIOS does not accept a particular translation geometry even
though that geometry is listed as an option during system setup.
• Make sure that the host adapter is not assigned an interrupt
that is already in use by another device. Modify the interrupt
jumpers if necessary.
During the FDISK program, the error message, “No Fixed
Disk Present,” appears.
• Check all cables.
• Check the power supply.
• Reboot the computer and make sure the drive spins up.
• Verify the BIOS drive type.
• Check for I/O address conflicts.
During high-level formatting, the drive keeps finding hard
errors and reporting the following message. “Attempting to
recover allocation units. . .”
• This is normal with DOS Version 4.0 or later. The drive will
format normally. However, after formatting the drive, you may
want to run a third-party surface-scan program to check for
bad sectors.
During high-level formatting, the drive does not format to
full usable capacity.
• Verify the BIOS drive type. Your drive’s formatted capacity is
limited to the capacity of the BIOS geometry you selected. If
your BIOS does not offer a geometry that takes advantage of
the full capacity of the drive, and a user-defined drive type is
not available, use a third-party partitioning utility.
ST9300 Family Installation Guide, Rev. A 15
• Run FDISK again and make the partitions smaller. If you are
using a version of DOS prior to Version 4.0, make the drive
partitions smaller than 32 Mbytes.
At startup, the DOS messages, “Disk Boot Failure,” “NonSystem Disk,” or “No ROM Basic - SYSTEM HALTED,”
appear.
• Run the FDISK program and make sure the primary partition
is marked active.
• Check all cables.
• Check your DOS version.
• Reinstall the DOS system files onto the hard disc using the
SYS command (see your DOS manual).
• Check for viruses.
During operation, the system error message, “Drive not
Ready,” appears.
• Check all cables.
• Check the power supply.
• Reboot the computer and make sure the drive spins up.
Compatibility notes
• The ST9300 family drives conform to the ATA interface specifications. The host system BIOS must provide support for the
ATA interface command set. For a detailed description of the
ATA commands implemented by these drives, see the
gate ST9300 Family Product Manual
Interface Reference Manual
• In accordance with ATA specifications, the system BIOS must
reset any emulation/translation parameters after a hard reset.
.
and the
Seagate ATA
Sea-
16 ST9300 Family Installation Guide, Rev. A
• In some configurations, the ST9300 family drives may supply
up to 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
a different number of bytes, some drive diagnostic programs
may fail, typically resulting in time-out errors. Consult your
computer documentation or call your computer dealer or
manufacturer for information on configuring your computer to
receive more than 4 bytes of ECC.
• Some older drive diagnostic programs may incorrectly report
an ECC-detection failure when analyzing an ST9300 family
drive. This occurs because the drive hardware corrects the
data automatically, avoiding the error rather than reporting it.
Such a report does not indicate a drive malfunction.
