Where to call for Seagate technical support
Seagate provides installation software, EZ-Drive, and a 32-bit
disk access driver for Windows, SEG32BIT.386, that allows the
computer to surpass the 528-Mbyte barrier when it is imposed.
The software is stored on the drive and must be transferred to a
diskette in Drive A before you partition and format the drive. A
program called Seamove is provided to make the transfer easy.
We hope your installation goes smoothly, but if complications
arise, a list of common symptoms and solutions is providedin the
troubleshooting section. If the problem persists, contact your
dealer first. Your dealer is familiarwith systemintegration and the
conflicts that arise. If you need additional help or information
about Seagate products, Seagate technical support numbers are
provided.

Before you begin...
Note. Throughout this manual the Medalist 1270 is referred to by
its model number, ST31270A.
Drive handling. Your drive is vulnerable to damage from rough
handling and static discharge. Do not drop your drive. Do not
remove the seals and labels on the drive. The drive warranty is
voided if the seals and labels are removed.
Static discharge. Your drive contains components that can be
damaged by static discharge. Static damage can be cumulative
and may not manifest immediately. Observe the following pre-
cautions:
•
Ground yourself before handling the drive. Wear a ground
strap that is properly connected to earth ground, or touch the
metal of a power supply that is plugged into a wall outlet while
handling the drive.
•
•
•
Keep the drive in its antistatic bag until you are ready to install
it. Do not attach any cables to the drive while it is in its bag.
Handle the drive gently and only by its edges or frame. Place
it on an antistatic surface until you are ready to install it.
Do not touchthe drive’sconnectorpins orprintedcircuitboard.
Inspection. Use the handling precautions listed above when you
inspect the drive. If it appears to be damaged, call your distributor
or dealer immediately.
Warranty. The drive comes with a three-year limited warranty.
Note. Withregardsto the EZ-DriveandSEG32BIT.386software,
there are no warranties, express or implied, including, but
not implied, warranties of merchantablity or fitness for a
particular purpose. All such warranties are expressly and
specifically disclaimed.
Maintenance and repair. Seagate drives do not require mainte-
nance. The head/disc assembly is sealed; a broken seal voids
the warranty. Seagate customer service centers are the only

Configuring the drive
Required materials:
•
0.100-inch jumper connectors (supplied as spare jumpers)
Your Seagate drive is configured using the options jumper block
shown in Figure 1 on page 6. You can configure the drive:
•
•
•
•
For one- or two-drive operation
To be the master or slave drive
For dual-drive emulation
To operate as the master with drives that use a different
master/slave timing protocol
•
•
For computers that use cable-select
To use a remote drive-activity LED
To configure the drive, attach a jumper to the pins on the options
jumper block as shown in Figure 2 on page 7 for the desired
option. The configuration options are:
Spare jumper. Use the spare jumpers on pins 1 and 3 and
pins5 and 7to configurethe drive. These settingsare not used
for drive operation.
One-drive only. Use this configuration if there are no other
drives attached to the hard disc controller.
Master with slave present. Use this configuration if the drive
is the first of two drives in your system. The master drive is
drive 0 in the System Setup record.

Slave. Use this configuration if the drive is the second drive in
the system. The slave is drive 1 in the System Setup record.
Master/slave timing protocol. This protocol involves the
communication between the computer and the disc drives
during the power-on cycle only. The computer queries the
master drive for the status of both drives. The slave must
report its status to the master within a certain time period. If it
does not respond in time or if it uses a response signal that
the master does not acknowledge, the master tells the host
that the slave has timed out, and the computer does not
recognize the slave. The Seagate drive is shipped configured
to work with other drives that comply with the ATA-standard
master/slave timing protocol.
This setting allows the Seagate drive in the slave position to
respond to some drives that use a different protocol. Try using
this setting if the slave is not identified after power-on.
Dual-drive emulation. This feature allows you to make the
most of the BIOS limitation by making the drive two logical
drives for the computer. Each logical drive is assigned a drive
type in System Setup using the maximum translation geome-
try values the BIOS allows. Each logical drive must be parti-
tioned and formatted. A second, physical drive cannot be
attached to the hard disc controller. You cannotuse dual-drive
emulation with cable select.
Cable-select. Use this configuration if your computer uses
cable-select.
Remote LED. If your computer uses a remote drive-activity
LED, place the ground wire side of the connector, usually the
black wire, on pin 13 (–) and the other side on pin 14 (+) of the
options jumper block. The LED can be damaged if the cable
is attached incorrectly.
The options jumper block accepts a 0.100-inch connector. It
maybe necessary toreplacethe current connector ontheLED
cable with a 0.100-inch connector.
Medalist 1270 Installation Guide, July 1995
9
Attaching the cables
Required materials:
•
A 40-conductor interface cable with a 40-pin, female interface
connector for each drive you want to attach.
•
A four-conductor power-supply cable.
Note. To ensure the integrity of your data, use a nonshielded
cable with a maximum length of 18 inches (46
centimeters).
This section refers to Figure 1 on page 6.
1. Attach the interface cable. Pin 1 on the drive must align with
pin1of the hard-disc controller connector. Usethe edge-stripe
on the cable to denote pin 1. Pin 1 on the drive is located next
to the four-pin power connector.
Caution. The cable and connector bond is delicate. Pulling the
cable to remove the connector may damage the cable.
Attach an interface connector to the drive. If your interface con-
nector has a key, it can only plug into the drive one way. Be sure
that you do not bend the pins when you attach the cable.
Attach an interface-connector to the hard-disc controller connec-
tor on the motherboard or host adapter. Be sure that pin 1 (see
your system user’s guide or host adapter user’s guide to deter-
mine the location of pin 1) is aligned with pin 1 on the drive.
Cable-select installation: If your computer uses cable-select,
refer to its user’s guide to determine which interface connector is
used for the master and which is used for the slave.
2. Attach a power-supply cable to the drive.
Caution. The cable and connector are designed to mate. Do not
force a connection. Improper alignment can damage
your drive.
10
Medalist 1270 Installation Guide, July 1995
Mounting the drive
Required materials:
•
Four 6-32 UNC-2A screws (not included)
The drive fits in the standard 3.5-inch bay and can be mounted
in any orientation. Secure the drive with fourmountingscrews not
more than 6 full turns (0.20 inches) into the drive frame (see
Figure 3). Position the drive so that the cables are not strained or
crimped.
Caution. To prevent drive mounting-hole damage, use only the
type of screws specified.
This completes the hardware installation.

Transferring the software from the drive
Required materials:
•
•
•
Diskette Drive A
A blank diskette that can be used in Drive A
A bootable diskette with the Format command
Recent developments in drive technology have pushed drive
capacities beyond the limit thatmany oldercomputers using DOS
can address. Seagate provides software solutions that can allow
your computer to surpass the address limit and access the full
capacity of your drive. The software is stored on the drive at the
factory and must be transferred to a diskette in Drive A before
you partition and format the drive. The files stored on the drive
include:
•
•
•
EZ-Drive. This is drive installation software that enables com-
puters with BIOSs that restrict the hard disc capacity to 528
Mbytes to surpass the 528-Mbyte barrier.
SEG32BIT.386. This replacement 32-bit diskaccess driverfor
Windows supports drive capacities above 528 Mbytes, multi-
ple block read/write, PIO modes 3 and 4 and LBA addressing.
Seamove. This is a program that automatically copies the
software files stored on the drive at the factory to a bootable
diskette in Drive A. It removes the factory-installed partition
and format when the files are copied.
•
README. This file contains information about the Seamove
transfer program.
You must create a diskette with the software that Seagate pro-
vides. To transfer the software, put a bootable,blankdiskette into
Drive A. To create a bootable diskette:
1. Insert your DOS diskette into Drive A.
2. Type format a: /s.
The drive reads the DOS diskette and prompts you to insert
the diskette you want to format into Drive A.
12
Medalist 1270 Installation Guide, July 1995
3. Insert the blank diskette. Press ENTER. When the format is
complete, you can transfer the installation software files to the
diskette.
To transfer the software files:
1. Boot the computer with the diskette to which you want to
transfer the software files.
2. Enterthe System Setup. (Referto yourcomputeruser’s guide.
System Setup may be called Setup, BIOS Setup or CMOS
Setup.) If your computer uses an automatic setup system, go
to step 5.
3. Find the hard disc configuration in the System Setup screen.
4. Select drive type 2 for your new Seagate drive. If your com-
puter does not offer drive type 2, use the following values: 615
cylinders, 4 heads and 17 sectors.
Note. These are interim drive-type values that allow you to
access the drive for extracting the installation files.
5. Activate the prompt for the Seagate drive.
6. Type seamove and press ENTER.
This command transfers the files from the drive to the diskette
in Drive A. When the transfer is complete, the seamove
program erases the files and the drive partition and reboots
the computer. The computer returns an invalid drive-specifi-
cation error if you try to access the drive.
Caution. Do not write-protect the Seagate software diskette with
EZ-Drive. The EZ-Drive program writes important in-
formation back to the diskette during the installation.
Medalist 1270 Installation Guide, July 1995
13
Determining if your BIOS accepts more
than 528 Mbytes
The following suggestions can help you to determine whether
your BIOS limits the drive capacity to 528 Mbytes.
•
If you are using a 286 or 386 computer, the native BIOS does
not recognize more than 528 Mbytes.
•
If the copyright date of the BIOS is earlier than 1994, it
probably will not recognize more than 528 Mbytes. The BIOS
copyright date, manufacturer and version number appear on
your screen at the beginning of power-on or reboot.
•
Install the drive using the Standard setup described on page
18. (Transferthe free software stored on the drive to a diskette
before you start the installation. See page 11 for transfer
instructions.) When the installationis complete, type dir d: for
the new drive and checkthe numberof bytes free. The number
should be close to the formatted capacity of your drive. If the
number is less than 528 Mbytes, you need to consider alter-
natives for surpassing the 528-Mbyte barrier. Some alterna-
tives are listed below.
Solutions for surpassing the 528-Mbyte barrier
•
Upgrade theBIOSto onethatsupports morethan528 Mbytes.
Such BIOSs incorporate logical block addressing (LBA) and
extended cylinder-head-sector (ECHS) addressing.
•
•
Use a host adapter that supports more than 528 Mbytes.
Use the free installation software, EZ-Drive, that is stored on
the drive at the factory or an equivalent. (See page 11 for
instructions on transferring the software to a diskette. See
page 16 for instructions on using EZ-Drive.)
•
Use dual-drive emulation. Dual-drive emulation makes the
drive two logical drives for the computer. Each logical drive is
assigned a drive type in System Setup and is partitioned and
formatted. However, you can only use the translation geome-
14
Medalist 1270 Installation Guide, July 1995
try values allowed by the BIOS, which limits the capacity of
each logical drive to 528 Mbytes.
Configuring the computer
Configuring the computer involves updating the computer’s Sys-
tem Setup records with the new drive’s translation geometry
(cylinder, head and sector information) and partitioning and for-
matting the drive. The translation geometry is kept on the CMOS
chip and is used by the BIOS to assign locations for the data on
the drive. Many older BIOSs place limits on the translation
geometry parametervaluesthat do not allowit to assignlocations
beyond 528 Mbytes when DOS is used. If your computer uses
such a BIOS, it cannot access the full capacity of your new drive.
In this section we describe three methods you can use to config-
ure your computerforDOS: EZ-Drive installationsoftware, stand-
ard setup and dual-drive emulation setup.
Using the installation software
Note. The EZ-Drive software is authorized for installation only
with the drive on which it is shipped.
The EZ-Drive installation software allows your computer to ac-
cess your Seagate drive’s full format capacity. It bypasses the
BIOS during the boot sequence and uses the information it
creates on Drive C to identify the drive before DOS is loaded.
During the installation, EZ-Drive:
•
•
•
Determines how many drives are installed
Enters a drive type in System Setup for the new drive
Modifies the Drive C boot record with the new drive’s transla-
tion geometry
•
•
•
Partitions and formats the new drive
Copies the boot files to the new drive if it is Drive C
Enables Maximum Overdrive, which enables read/write mul-
tiple in drives that have this feature. The Change Installed
Medalist 1270 Installation Guide, July 1995
15
Features option thatappears in thedialogbox whenthe format
is complete allows you to disable Maximum Overdrive.
EZ-Drive is easy and safe to use. You can choose a fully-auto-
matic installation,whichputs a singlepartition on the drive, or you
can install the drive with multiple partitions and other custom
features. Online help is provided for selected topics when you
press F1. Online help is also available in the main menu as
Information Help.
If you already have a drive installed, EZ-Drive cannot harm your
data unless you instruct it to override that drive’s partition and
format. EZ-Drive automatically arranges the drive-type position
in System Setup to reflect how you have physically configured
the drives.
Note. EZ-Drive is designed for DOS installations. To use EZ-
Drive, you must have:
•
•
•
•
•
Microsoft MS-DOS Version 3.0 or later
IBM PC-DOS Version 3.1 or later
Digital Research DR-DOS Version 6.0 or later
Novell DOS Version 7.0 or later
Compaq DOS Version 3.1 or later
EZ-Drive allows you to have full access to your drive in
DOS when other operating systems are loaded on the
drive. You must install the drive with EZ-Drive and DOS
before loading the other operating system. (See the Infor-
mation Help option in the software for more information on
installing other operating systems.)
EZ-Drive does not support:
•
•
Toshiba laptops, XT or Micro Channel computers
Non-ATA hard drives (SCSI, ESDI, MFM and RLL)
Caution. Because EZ-Drive uses about 4 Kbytes of conven-
tional memory, some older virus-detection programs
may misidentify EZ-Drive as a virus. If all 640 Kbytes
16
Medalist 1270 Installation Guide, July 1995
of conventional memory are not free when these virus
programs inspect conventional memory, they assume
a virus is present and clean and restore the memory.
If this happens, information about the EZ-Drive in-
stalled drive is destroyed, and the drive cannot be
identified by the computer. Do not use these programs.
Note. The Seagate versionof EZ-Drive cannotinstall a non-Sea-
gate drive without a Seagate drive present.
1. Boot your computer with the Seagate software diskette with
EZ-Drive. This is a precaution to ensure that the EZ-Drive
installation does not conflict with any terminate-and-stay resi-
dent (TSR) programs that may be in memory.
2. Type ez and press ENTER.
3. Disregard the Notice dialog box. The EZ-Drive software is
authorized for installation only with the drive on which it is
shipped. Press ENTER to continue.
4. Locate the bottom box on the screen. The model number of
each drive EZ-Drive identifies is listed in this box. If a drive you
have installed is not listed or the drive order (Drive 0 is the
master, Drive 1 is the slave) is incorrect or there is a drive not
identified message, make sure the master and slave jumpers
are set correctly on the drives and the I/O and power cables
are properly connected.
Note. Other troubleshooting tips are available in the Information
Help menu.
Caution. Turn off your computer before resetting the jumpers or
removing the cables.
5. If the drives are correctly identified, select Fully Automatic
Installation in the Main menu dialog box above. This creates
a single partition and formats the drive.
If you are installing the drive as Drive C, EZ-Drive automat-
ically writes the system files to the drive to make it bootable.
Medalist 1270 Installation Guide, July 1995

6. When the format is complete, the Options dialogbox appears.
We want tocallyourattentionto twoof theoptions inparticular:
Create Recovery Disk and Change Install Features.
Create Recovery Disk allows you to save the boot information
EZ-Drive uses to load your drive. You can use this diskette to
restore the EZ-Drive boot information on Drive C if it is cor-
rupted and you cannot access the drive. Use a blank diskette
to create the recovery disk. We recommend that you use this
feature.
Change Install Features allows you to change the status of
some EZ-Drive features. You can:
•
•
•
Disable Maximum overdrive.
Disable the EZ-Drive banner that appears during boot up.
Disable Floppy Boot Protection. This allows you to use the
EZ-Drive installed drive with other operating systems.
Caution. You can corrupt the data on your drive if you boot
from a diskette improperly while in this mode.
Always follow the “Booting with a diskette after
EZ-Drive is installed” instructionon page 18 orthe
Floppy Boot Instruction in EZ-Drive when booting
with a diskette in this mode.
•
•
Set the time period the computer allows you to press CTRL if
you want to boot to a floppy.
Remove the EZ-Drive boot code from Drive C.
7. Select Reboot to reboot the computer and save the installa-
tion. Remove the diskette.
Toward the end of the bootsequence, yourscreen shoulddisplay
a prompt for booting with a diskette followed quickly by the Micro
House banner and the C: prompt. If the boot prompt and the
banner fail to appear and you have not disabled Floppy Boot
Protection in the Change Install Features menu, your computer
has not recognized the EZ-Drive installed drive.
18
Medalist 1270 Installation Guide, July 1995

Medalist 1270 Installation Guide, July 1995
Partitioning and formatting the drive
Before you can use your Seagate drive, you must partition and
high-level format it. In this guide we discuss formatting your drive
with DOS—refer to your DOS user’s guide for assistance. If you
are using another operating system, consult your operating sys-
tem user’s guide for formatting instructions.
Note. If you have not copied the free installation software to a
diskette, your computer will detect a partition on the drive.
Only the first two cylinders are formatted at the factory to
store the software files. You must erase this partition
before you can access the full drive capacity. You can
eithertransferthe files to a diskette—thepartitioniserased
when the transfer is complete—(see page 11 for instruc-
tions) or partition and format the drive as described below.
Low-level formatting
The drive is low-level formatted at the factory using512 bytes per
sector. Low-level formatting is not required.
Partitioning
You must partition the drive into one or more logical drives before
you can use it.
Caution. Partitioning or formatting a drive at any level erases all
data on it. Make a backup copy of your existing files on
another drive before you repartition or reformat. Sea-
gate assumes no liability if you erase your data.
You can partition a drive as follows:
1. Insert a bootable diskette into Drive A. Turn the computer on.
2. After the computer has completed booting, remove the boo-
table diskette from Drive A. Insert a diskette that has the
FDISK utility into Drive A and type fdisk. Press ENTER.
Note. If youhavetwodrivesinyoursystem,the menudisplays
five options. Option five allows you to select the drive
you want to partition. Be sure to select the correct drive.
Medalist 1270 Installation Guide, July 1995
21
3. Selectcreate DOS partitionorlogical DOS drive. Press ENTER.
4. Select create primary DOS partition. Use the maximum avail-
able size for your primary partition and make the partition
active for Drive C. This puts the entire drive on one partition
and allows you to load the DOS boot information on the drive.
Press ENTER for each subsequent selection.
After all of the appropriate selections are made, the computer will
restart itself. You must place a bootable diskette into Drive A.
High-level formatting
High-level formatting verifies the information written by the low-
levelformat and builds thefile allocation table(FAT)used byDOS
to access files on the drive. If you put more than one partition on
the drive, you must high-level format each partition. Refer to your
DOS reference guide for instructions. Use the DOS FORMAT
utility to high-level format the drive as follows:
1. At the DOS prompt, type the following command:
format drive: /v /s
drive: designates the drive you are formatting. If you are
formatting the boot drive or if your system contains only one
drive, type c:. To format a second drive, type d:.
/v tells the computer to create a volume label for the partition
after it is formatted. Labeling can prevent someone from
accidentally deleting the partition and losing your data.
/s tells the computer to copy the necessary system files to the
drive to make it bootable.
2. When the computer prompts you for a volume label, you can
use up to eleven characters to name the drive volume (see
your DOS reference manual) or leave it blank. Press ENTER.

Basic troubleshooting
Warning. Always turn off the computer before changing jumpers
or unplugging cables and cards.
Caution. Your drive and computer contain static-sensitive de-
vices. Wear a ground strap or take other antistatic
precaution while handling your drive.
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 the
drive are appropriately matched to each other and to your
computer. Refer to relevant documentation for details.
•
•
Check all cards. Verify that all cards are seated in their slots
on the motherboard and are secured with mounting screws.
Check all cables. Make sure all ribbon and power cables are
securely connected. Ribbon cables are easily damaged, es-
pecially at the connector. Try a new cable or a known good
cable. Make sure no socket pins were bent when the cable
was inserted. For each cable, verify that cable-connector pin
1 is aligned with equipment-connector pin 1. The edge-stripe
on the ribbon cable is used to denote pin 1.
Caution. Do not reverse-plug connectors. This can damage
the computer and the drive.
•
Verify equipment configuration. Review the instructions in
this guide and the host adapter installation guide and make
sure that all appropriate jumpers are installed, or removed, to
suit your application.
•
•
Check the power-supply specifications. If new devices are
installed, your computer’s power supply may not support the
new total power requirement. Consult your dealer.
Verify the drive type setting in System Setup. The drive
type stored in CMOS memory by your System Setup program
must notexceedthe physical specifications of yourdrive. Also,
24
Medalist 1270 Installation Guide, July 1995
if you have a large-capacity drive, the translation geometry
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 prob-
lemhasnotbeen solved, follow theseguidelines fortroubleshoot-
ing specific cases:
The system does not recognize the drive.
•
•
•
Check all cables.
Make sure the power supply is adequate for system needs.
Reboot the computer and make sure the drive motor runs. If
yourdrive is very quiet, itmay be difficult tohearits discs reach
operating speed. Recheck all drive cables if the drive is not
running.
•
•
Verify the SystemSetup drive-type values. Each drive present
must be represented in System Setup.
Try a warm boot (arebootwithoutturningoff computerpower).
To do this, press CTRL, ALT, and DELETE at the same time.
If the drive is recognized after the warm boot, the computer
BIOS’ setup test may be completing before the drive is ready.
One possible solution is to slow your computer’s processor
speed during startup. If your computer has a turbo switch, set
it to slow speed before turning the computer on. If there is no
turbo switch, you may be able to use keyboard commands to
slow the processor speed; see your computer manual for
details. After the computer is up and running, return the
processor to the fast speed.
Another solution is to warm-boot your computer after every
power-on.
•
Check for I/O address conflicts. To isolate the conflict, first
Medalist 1270 Installation Guide, July 1995
25
verify that the drive and host adapter are compatible with your
computer by removing all the peripheral adapter cards (power
must be off) except for the video card. Then reinstall the drive
and host adapter card. If this is successful, reinstall the other
peripherals one at a time until the conflict reoccurs.
After you have isolated the source of the address conflicts,
you can resolve the conflictby changingthe I/O address of the
peripheral that appears to cause the conflict.
•
•
If yourdrivewasinstalled with EZ-Drive, thespecial instruction
in the boot sequence on Drive C may have been bypassed.
Remove the diskette and reboot. For instructions on how to
boot with a diskette, see the section “Booting with a diskette
after EZ-Drive is installed” on page 18.
If the computer does not recognize the slave drive after
power-on, the slave may not be communicating with the
master during the boot cycle. Try reconfiguring the drives
using the master/slave timing protocol jumpers discussed on
page 8.
The dealer partitioned and high-level formatted the drive for
you in the store. Later, you installed the drive and it does not
respond.
•
•
•
•
Reboot the computer and make sure the drive spins up.
Check all cables.
Make sure the power supply is adequate for system needs.
Use the same version of DOS within all partitions. 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. If it isn’t, see your dealer.
•
Verify the System Setup drive-type value. You must install the
drive using the same drive type or translation geometry that
your dealer used to partition the drive.
•
•
Check for I/O address conflicts between peripheral cards.
Check for viruses.
26
Medalist 1270 Installation Guide, July 1995
The screen remains blank when you power up the system.
•
•
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 are se-
curely attached.
While the computer is powered down, remove the drive host
adapter. If the screen turns on after you reboot, the host
adapter may be incompatible or defective. If so, see your
dealer.
The system hangs in FDISK or fails to create or save the
partition record.
•
•
Check all cables.
The DOS utilities diskette may be corrupted. Try your backup
DOS diskette.
•
•
Make the partitions smaller.
Tryanother drivetypeortranslationgeometry.Thecomputer’s
BIOS may not accept a particular translation geometry for
writing into the CMOS setup memory.
•
•
Change the interrupt jumper setting on the host adapter.
Check for media defects at the beginning of the drive. Use a
third-party surface scan utility.
•
Some BIOSs have a Track 0 protection feature that protects
Track 0 from viruses. This can causes FDISK to hang the
system. You must disable this feature in System Setup before
you can use FDISK. See your computer reference guide for
assistance. Be sure to re-enable this important feature when
FDISK is done.
System error message, “Drive not Ready,” appears.
•
Check all cableconnections. Foreach ribbon cable, verify that
pin 1 of the cable is matched to pin 1 of the connector. Pin 1
is usually denoted by the edge-stripe on the ribbon cable.

The drive does not format to full capacity.
•
Verify your computer’s System Setup drive-type values. One
of the following problems may have occurred: 1) the values
may be set for an incorrect drive type or translation geometry;
2)you may have entered a parametervaluethat exceeded the
physical capacity of the drive; 3) you selected a translation
geometry or drive type that does not take full advantage of the
drive’s capacity; or 4) the drive’s physical specifications ex-
ceed the translation geometry limits imposed by the BIOS.
Refer to “Standard setup” on page 18 if any of the first three
cases are true. Refer to “Configuring the computer” on page
14 if the last case is true.
If you reset the System Setup drive-type value, you must
partition and high-level format the drive again.
•
•
•
If you partitioned the drive into individual logical drives, you
may need to make the partitions smaller so that the computer
can use all of the drive’s capacity.
If your computer supports LBA mode, you may need to enable
an LBA mode function in System Setup to get the drive’s full
capacity. Refer to your computer’s reference guide.
You can use the EZ-Drive software to install the drive.
DOS messages “Disk Boot Failure,” “Non-System Disk,” or
“No ROM Basic - SYSTEM HALTED,” appear.
•

A device conflict occurs between the native Windows 32-bit
disk access driver and drives with more than 528 Mbytes. To
get the advantages of 32-bit disk access and more, install the
SEG32BIT32-bitdiskaccessdriver. See“Windows32-bitdisk
access” on page 21 for installation instructions.
Disabling EZ-Drive
To disable EZ-Drive, remove the EZ-Drive boot information writ-
ten to the boot sector of Drive C. Your computer will stop access-
ing EZ-Drive-installed drives with more than 528 Mbytes. The
data filesare not affected. Forthis operation, you need abootable
diskette and a diskette that has the FDISK utility.
Note. Before you disable EZ-Drive, back up your data files.
1. Turn the computer off.
2. Insert a bootable diskette into Drive A and turn the com-
puter on. Your computer must boot to Drive A without
loading EZ-Drive into the system memory.
3. When the boot cycle is complete, place a diskette that has
the FDISK utility in Drive A if it is not on the boot diskette.
4. Type fdisk/mbr and press ENTER. This command erases
the EZ-Drive-modified master boot record on Drive C and
replaces it with the standard DOS master boot record. The
computer can no longer identify drives with more than 528
Mbytes installed using EZ-Drive. You must partition and
format the drive to make it accessible (see page 20).
