The easiest way to install your drive  
DiscWizard is Seagate’s exclusive Win-  
dows program, provided on a diskette, that  
makes it easy to install your Medalist drive.  
DiscWizard helps you configure your new  
drive and your computer. It analyzes your  
system, lets you select various installation  
options and creates customized step-by-  
step instructions. It also allows older computers to access the full  
capacity of large-capacity drives.  
You can run DiscWizard to install your new hard drive if:  
You already have an existing, bootable hard drive in your com-  
puter with at least 3 Mbytes of available disc space, and  
You are running Windows 95 or Windows 98.  
If you can run DiscWizard, follow the instructions on the  
DiscWizard diskette to install your drive. If you need additional  
information, refer to this installation guide.  
If you cannot run DiscWizard, follow the instructions in this  
installation guide to install and configure your new drive.

Medalist 8421, 6421, 4311 and 2112, Rev. A  
What you need  
Straight-edge and Phillips screwdrivers  
Four 6-32 UNC drive mounting screws  
A standard 40-pin ATA interface cable, or  
an 80-conductor cable if your system runs Ultra DMA mode 3  
or 4 (max length: 18 inches)  
An unused drive power cable for your new drive  
Before you begin  
Make sure your computer is turned off before you open the  
case.  
Read the handling precautions at the right and inspect the  
drive to make sure that it is not damaged.  
Save your foam-lined Seagate disc drive box. This box has  
been approved by Seagate for shipping a Seagate disc drive.  
Using any other container or packing material voids your drive  
warranty.  
Medalist 8421, 6421, 4311 and 2112, Rev. A

Handling precautions  
Disc drives are extremely fragile. Do not drop or jar  
your drive.  
Keep the drive in its antistatic bag until you are  
ready to install it.  
Protect your drive from static discharge by making  
sure you are well grounded before touching the  
drive. We recommend wearing a grounded wrist  
strap throughout the installation process. Do not  
touch the connectors or any part of the printed cir-  
cuit board.  
Always handle the drive by its edges or frame.  
Do not apply pressure or attach labels to the circuit  
board or the top of the drive.

Medalist 8421, 6421, 4311 and 2112, Rev. A  
Master/slave jumpers  
If you already have one hard drive in your computer and you are  
installing a second drive, you must configure one drive as a mas-  
ter and the other as a slave.  
Note. If you need to change the jumpers on your existing hard  
drive, see the Disk Manager online manual, look on the  
drive label, or contact the drive manufacturer.  
To configure the drive as a master or one drive only:  
The drive is configured at the factory for a master or single-  
drive operation with a jumper set on pins 7 and 8.  
Note. The master drive usually defaults to being the “boot” drive  
(drive C), from which the computer loads system soft-  
ware when it first starts up.  
To configure the drive as a slave:  
Remove the jumper to configure the drive as a slave.

Attaching cables and mounting the drive  
1. If you are attaching an ATA (IDE) interface cable to a single  
drive, attach one end of the cable to the interface connector  
on your motherboard. Most computers provide two IDE con-  
nectors, primary and secondary, usually labeled as IDE or  
HDD on your motherboard. See your computer manual for  
connector locations.  
Note. If you are running Ultra DMA mode 3 or 4, you must use a  
special 40-pin 80-conductor cable or these modes will not  
be enabled. For information on how to obtain this cable,  
contact your dealer.

Figure 2. Attaching the cables  
2. Thread the interface cable through the drive bay and attach  
the connector at the end of the interface cable to your new  
drive (the maximum ATA cable length is 18 inches (457 mm)  
long).  
Medalist 8421, 6421, 4311 and 2112, Rev. A

Note. If you are using the 80-conductor cable, attach the blue  
connector (with the longest section of the cable) to the  
motherboard, attach the black connector to the master or  
single drive, and attach the grey connector to the slave.  
Caution. To avoid possible damage to your system,  
make sure to align pin 1 on the motherboard with pin 1  
on your drive. Pin 1 on the interface cable is usually  
indicated by a stripe along the edge of the cable.  
!
Figure 3. Mounting screws  
3. You can mount the drive in any orientation. Usually it is  
mounted with the circuit board down.  
4. Slide the drive carefully into the drive bay. Secure the drive  
with four 6-32 UNC mounting screws in either the side-  
mounting holes or the bottom-mounting holes. Insert the  
screws no more than 0.22 inch (5.58 mm) into the bottom-  
mounting holes and no more than 0.20 inch (5.0 mm) into the  
side-mounting holes.

Caution. To avoid possible damage to the drive, do not  
overtighten the screws or use metric screws.  
!
Note. If you are mounting the drive in a 5.25-inch drive bay, you  
need a mounting adapter or frame kit. Contact your com-  
puter dealer. Some computers also require drive mount-  
ing rails, which can usually be obtained from your dealer.  
5. Attach a power cable to the drive. If your computer does not have  
an unused power connector, you can purchase a Y-shaped  
power cable from your computer dealer.  
6. Check all cable connections and then replace your computer  
cover. Continue to “Configuring Your Computer.”

Configuring your computer  
Before you format or partition your new drive, you must configure  
your computer’s BIOS.  
To configure your computer’s BIOS:  
1. Turn your computer on. As your computer starts up, watch the  
screen for a message that describes how to run the system  
setup program (also called BIOS or CMOS setup). This is  
usually done by pressing a special key, such as DELETE, ESC  
OR F1, during startup. See your computer manual for details.  
Press the appropriate key to run the system setup program.  
2. Select the BIOS hard drive settings menu. To set the drive  
parameters, choose Primary Master or Slave, or Secondary  
Master or Slave.  
3. Select automatic drive detection if available. This option allows  
your computer to configure itself automatically for your new  
drive. If your BIOS does not provide automatic drive detec-  
tion, select “User-defined” drive settings and enter the CHS  
values from the table on page 10. These CHS values support  
capacities up to 8.4 Gbytes.  
4. Verify that LBA mode is enabled. Many BIOS use the logical  
block addressing (LBA) mode to access drives with capacities  
greater than 528 Mbytes. Most BIOS automatically set this  
mode during the auto-detection process.  
5. Enable UDMA mode if it is available. To run in Ultra DMA  
mode 3 or 4, the system requires a special 40-pin 80-conduc-  
tor cable to ensure signal integrity. These modes will not be  
enabled unless the 80-conductor cable is present.  
6. Save the settings and exit the System Setup program (your  
computer will automatically reboot).

Recommendation  
We recommend you use Disk Manager to evaluate your BIOS  
and determine whether your system needs additional BIOS sup-  
port. If your BIOS needs support for drives with capacities  
greater than 8.4 Gbytes, instructions will be provided. For more  
information, see “Installation using Disk Manager” on page 14.  
Medalist 8421, 6421, 4311 and 2112, Rev. A  
11  
Addressing drive-capacity limitations  
Some DOS-based computers and operating systems are not  
designed to accommodate large-capacity hard disc drives. The  
most common system limitations are listed below.  
528-Mbyte limit  
The BIOS in some older computers cannot support drives with  
capacities greater than 528 Mbytes. Seagate provides free Disk  
Manager software with your drive to overcome this limitation.  
Alternatively, you can purchase a hard drive controller or a BIOS  
upgrade that supports drives with capacities greater than 528  
Mbytes.  
The 32-bit disk access feature in Windows 3.1 does not work  
with drives that have capacities greater than 528 Mbytes. If you  
want to use 32-bit disk access with Windows 3.1, see the file  
SEG32BIT.TXT, located on your DiscWizard diskette, for further  
information.  
8.4-Gbtye limit  
If your drive’s capacity is greater than 8.4 Gbytes, the capacity  
may exceed the limits of your system BIOS and operating sys-  
tem. DOS and Windows operating systems and most system  
BIOS limit the drive partitions to 8.4 Gbytes per physical drive.  
Because of this limitation, a 32-bit file allocation table (FAT32) is  
needed to support drive capacities greater than 8.4 Gbytes.  
To achieve your drive’s full capacity, you need a Windows operat-  
ing system that supports FAT32 and device support for drive  
capacities greater than 8.4 Gbytes, from one of the following:

Third-party device driver, such as Disk Manager (Disk Man-  
ager is provided on the DiscWizard diskette included with your  
drive), or

Preparing your drive for use  
One-drive system  
For a quick installation we recommend you use Disk Manager to  
automatically partition and format your drive.  
Disk Manager also ensures that your computer can access the  
full capacity of your hard drive. See “Installation using Disk Man-  
ager” on page 14.  
If you do not want to use Disk Manager, you can use the stan-  
dard DOS commands to partition and format your drive. See  
“Standard DOS installation” on page 16.  
Two-drive system  
Use DiscWizard for a complete customized set of step-by-step  
instructions to install an additional drive. See “The easiest way to  
install your drive” on page 1.  
To add a slave drive without using DiscWizard:  
Use the FDISK.EXE command. See “Standard DOS installation”  
on page 16.  
To add a slave drive using Windows 95 or Windows 98:  
1. Click START.  
2. Choose RUN.  
3. Type FDISK. See “Standard DOS installation.”  
14  
Medalist 8421, 6421, 4311 and 2112, Rev. A  
Installation using Disk Manager  
1. Boot your computer from your DiscWizard diskette. Booting  
from a diskette ensures that the Disk Manager installation  
does not conflict with other software. The Disk Manager soft-  
ware is stored on this diskette and automatically starts.  
Or at the A: prompt, type DM and press ENTER.  
2. Follow the onscreen instructions until you see the Select an  
Installation Option menu.  
3. Select either (E)asy Disk Installation or (A)dvanced Disk  
Installation.  
Disk Manager lists all the hard drives that it detects. You  
should see your new Seagate drive and your existing hard  
drive, if any.  
If any hard drive is not recognized, exit Disk Manager and  
turn off your computer. Check all cables, jumpers and BIOS  
settings. Then start at step 1 to run Disk Manager again.  
4. If Disk Manager recognizes all your drives, select the drive  
you want to install and press ENTER. Disk Manager partitions  
and formats the drive.  
Important. If Disk Manager determines that your BIOS needs  
support for drive capacities greater than 8.4 Gbytes,  
instructions on booting from your A: drive will be pro-  
vided. Disk Manager installs a Dynamic Drive Over-  
lay (DDO) on your hard drive. If this driver has been  
installed, you should see a blue Disk Manager ban-  
ner each time you boot your computer. See the Disk  
Manager online manual for details.

5. Follow the instructions in the post-installation screens and  
continue with your Windows 95 or Windows 98 installation.  
Windows 95 or Windows 98 Installation  
1. Boot your computer from the Windows 95 or Windows 98 star-  
tup diskette with the CD-ROM loaded (Note the drive letter for  
your CD-ROM device).  
2. At the A: prompt, type x:setup, where x is the letter of your  
CD-ROM drive.  
3. Continue with the Windows setup instructions.  
You’re Done!

Standard DOS installation  
Caution. Partitioning or formatting a drive erases all  
data on it. Seagate assumes no liability if you erase  
your data.  
!
Drive partitioning  
Partitioning a hard drive divides it into sections (partitions) that  
function as separate logical drives (labeled C,D,E, etc.). To parti-  
tion your new drive:  
1. Insert a bootable DOS diskette into your diskette drive and  
restart your computer. (Seagate recommends using DOS Ver-  
sion 5.0 or greater.)  
2. Insert a DOS program diskette that has the FDISK.EXE and  
FORMAT.COM programs into your diskette drive. At the A:  
prompt, type FDISK and press ENTER.  
3. If you have two hard drives installed, the FDISK menu displays  
five options. Option five allows you to select the drive you  
want to partition. Make sure that your new drive is selected.  
4. Select “Create DOS partition or logical DOS drive” by pressing  
1, then press ENTER.  
5. Select “Create primary DOS partition” by pressing 1 again.  
Then press ENTER. Create your first drive partition. If you are  
creating a partition that will be used to boot your computer  
(drive C), make sure the partition is marked active.  
6. Create an extended partition and additional logical drives, as  
necessary, until all the space on your new hard drive has  
been partitioned.  
7. When partitioning is complete, FDISK reboots your computer.  
Medalist 8421, 6421, 4311 and 2112, Rev. A  
17  
Drive formatting  
Caution. Use the correct drive letters so that you do not  
format a drive that already contains data.  
!
At the A: prompt, type format x: /s, where x is the letter of your  
first new partition. Repeat the format process for all the new par-  
titions you have created.  
Note. From FDISK in Windows 95 or Windows 98, it is not nec-  
essary to add the /s to the format command because  
these system files are automatically added.  
After you format your drive, it is ready to use.  
You’re Done!

Figure 5. Non-ATA compatible and cable select jumpers  
Non-ATA compatible slave jumper  
If your computer does not recognize your new drive as a master  
in a two-drive system, the slave drive may not be ATA-compati-  
ble. You may be able to solve this problem by setting a jumper on  
pins 5 and 6 and a jumper on pins 7 and 8 as shown in Figure 5  
above.  
Cable-select jumper  
Some computers differentiate between master and slave drives  
using specially designed interface cables that have the line to pin  
28 (the Cable select pin) removed or cut at one connector. The  
connector that has pin 28 disabled is used for the slave drive.  
See your computer manual to determine whether your computer  
supports this feature. To configure your drive for cable select, set  
a jumper on pins 5 and 6 as shown in Figure 5 above.

Advanced Disk Manager options  
The Disk Manger online manual  
Disk Manager contains an extensive online manual. This manual  
includes detailed installation instructions, troubleshooting and a  
list of master/slave jumper settings for many popular hard drives.  
To view the Disk Manager online manual, insert the Disk Man-  
ager diskette into drive A and type A:\DM /H. Then press ENTER.  
You can also view the online manual from within Disk Manager  
by selecting (V)iew/Print Online Manual in the main menu.  
Booting from a diskette  
If Disk Manager installs the dynamic drive overlay (DDO) to  
access the full capacity of your drive, the DDO must load into  
memory before the operating system loads. This occurs auto-  
matically when you boot from your hard drive (drive C). However,  
if you boot from a diskette, the DDO will not be loaded and you  
will not be able to access your hard drive. The following proce-  
dure allows you to boot from a diskette and still access your hard  
drive.  
1. Boot the computer from the hard disc (with no diskette in the  
diskette drive).  
2. When the Disk Manager banner appears on the screen,  
immediately press the SPACEBAR (you have about 2 seconds).  
3. Insert your boot diskette and press the SPACEBAR again.  
If you boot from a diskette regularly, you can create a Dynamic  
Drive Overlay boot diskette. It loads DDO into memory and then  
loads the operating system. See the Disk Manager online man-  
ual for more information about creating a dynamic drive overlay  
boot diskette.  
20  
Medalist 8421, 6421, 4311 and 2112, Rev. A  
Supported operating systems  
The Disk Manager dynamic drive overlay provides support for  
drives with capacities greater than 528 Mbytes under MS-DOS,  
Windows 3.x, Windows 95, Windows NT 3.51, Windows NT 3.50  
(requires DM upgrade drivers), OS/2 V3.0 (Warp full pack), and  
OS/2 V2.0–3.0 (requires DM upgrade drivers).  
Before you install a non-DOS operating system on the drive,  
install DOS and Disk Manager and make sure that the drive is  
bootable. Instructions for running the dynamic drive overlay with  
other operating systems are available in the Disk Manager online  
manual.  
Removing the Dynamic Drive Overlay  
If Disk Manager installs a dynamic drive overlay (DDO) and you  
do not need this software to access the full capacity of your  
drive, you can remove the dynamic drive overlay without losing  
your data. However, if you do not have another method for  
accessing high-capacity drives, you will lose access to the full  
capacity of your drive (see “Addressing drive-capacity limita-  
tions” on page 11).  
Before you attempt to remove a DDO, make a backup copy of all  
the data on your hard drive. Also, run CHKDSK, SCANDISK or a  
third-party equivalent to detect and repair any damaged files  
before you follow the procedure on page 21.  
Caution. If the DDO migration program encounters a  
serious file problem or is interrupted by a power loss or  
hardware failure, the migration will fail and your data  
will be lost.  
!
Medalist 8421, 6421, 4311 and 2112, Rev. A  
21  
Follow these instructions to remove a DDO from a drive.  
1. Boot the computer to drive C.  
2. Insert your DiscWizard diskette into drive A.  
3. Type A:\DM to start Disk Manager.  
4. Select the Select Installation Options Menu.  
5. Select (M)aintenance Menu.  
6. Select (M)igrate Dynamic Drive. This program moves the  
data on your drive so that it can be accessed without the  
DDO. The migration may take up to an hour to complete,  
depending on the size of your drive.  
7. When the migration program has finished, exit Disk Man-  
ager.  
8. Remove the diskette and reboot the computer. Enter your  
system setup program (see your system manual for details).  
9. Configure the hard drive with the Cylinder/Head/Sector  
parameters.  
10. When your computer has rebooted, insert the DiscWizard  
diskette into drive A.  
11. Type A:\DM and choose the Maintenance Menu.  
12. Select Uninstall (D)isk Manager.  
13. Select the correct drive to uninstall.  
14. When the uninstall is complete, exit Disk Manager and  
reboot.  
Note. Disk Manager can also remove a drive overlay placed by  
the EZ-Drive program. Select (C)onvert Drive Format  
from the Maintenance Menu.

Medalist 8421, 6421, 4311 and 2112, Rev. A  
Troubleshooting  
If you have installed your drive and it does not function properly,  
perform the following basic checks:  
Warning. Always turn off the computer before changing  
jumpers or unplugging cables and cards. Wear a  
ground strap or use other antistatic precautions while  
working on your computer or handling your drive.  
Verify compatibility. Verify that the host adapter and drive are  
appropriately matched to each other and to your computer.  
Refer to the 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 connectors and cables. Make sure all ribbon and  
power cables are securely connected. Ribbon cables are eas-  
ily damaged, especially at the connector. Try a new cable that  
you know is good. Make sure no connector pins are bent. Ver-  
ify that pin 1 on the interface cable is aligned with pin 1 on the  
drive and host adapter (see Figure 2 on page 6).  
Verify jumper settings. Review the instructions in this guide  
and in your host adapter installation guide. Make sure all  
appropriate jumpers are installed or removed as necessary.  
Check your power-supply specifications. Each time you  
add a new device to your computer, make sure your com-  
puter’s internal power supply can support the total power  
demand. If necessary, consult your dealer for a new power  
supply.  
Medalist 8421, 6421, 4311 and 2112, Rev. A  
23  
Verify the drive-type settings in the system setup pro-  
gram. The drive-type settings in the system BIOS must not  
exceed the physical specifications of your drive. Also, the set-  
tings must not exceed the limitations set by the operating sys-  
tem and BIOS.  
Check for viruses. Before you use someone else’s diskette in  
your system for the first time, scan the diskette for viruses.  
Additional troubleshooting tips  
If you have performed the preceding basic checks but the prob-  
lem persists, follow these guidelines for troubleshooting specific  
cases:  
The screen remains blank when you power up the system.  
If the steps listed above do not remedy this problem, try the fol-  
lowing:  
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.  
Turn off the computer and 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 does not recognize the drive.  
Check all cables.  
Make sure the power supply is adequate for system needs.  
Reboot the computer and listen to make sure the drive motor  
starts up. If the drive is very quiet, it may be difficult to hear its  
24  
Medalist 8421, 6421, 4311 and 2112, Rev. A  
discs reach operating speed. If the drive motor does not start  
up, recheck all drive cables.  
Verify that for each drive, a drive-type value is listed in the sys-  
tem setup program.  
Try rebooting your computer by pressing the CTRL, ALT and  
DELETE keys simultaneously. If the drive is recognized after you  
reboot the system, the computer BIOS test may be completing  
before the drive is ready.  
One solution is to slow the 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; see your computer man-  
ual 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, verify  
that the drive and host adapter are compatible with your com-  
puter. Turn off the computer and remove all the peripheral  
adapter cards except for the video card and host adapter. If  
the computer recognizes the drive when you reboot the com-  
puter, turn off the computer. Reinstall the other peripheral  
cards, one at a time, until the conflict reoccurs. After you have  
isolated the source of the address conflict, you can resolve the  
conflict by changing the I/O address of the peripheral that  
appears to cause the conflict.  
If Disk Manager has installed the DDO on your hard drive and  
you have booted directly from a diskette, the information in the  
boot record for the drive may not have been loaded. Make sure

there is no diskette in drive A and reboot. If you want to boot  
from the diskette, follow the “Booting with a Diskette” instruc-  
tions under “Advanced Disk Manager Options” on page 19.  
The dealer partitioned and formatted the drive for you in the  
store, but the drive does not respond when you install it.  
Reboot the computer and make sure the drive spins up. Check  
all cables.  
Make sure the power supply is adequate for system needs.  
Make sure the DOS or Windows version the dealer used to  
partition and format the drive is the same version you have  
installed in your computer. If it isn’t, see your dealer.  
Verify the drive-type values in the system setup program. You  
must install the drive using the same drive-type values your  
dealer used to partition the drive.  
Check for I/O address conflicts between peripheral cards.  
Check for viruses.  
The system hangs in FDISK or fails to create or save the  
partition record.  
Check all cables.  
Your setup system diskette may be corrupted. Try using a  
backup diskette.  
Make the partitions smaller.  
Change the interrupt jumper setting on the host adapter.  
Some BIOS have a Track 0 protection feature that protects  
Track 0 from viruses. This may cause FDISK to hang the sys-  
tem. You must disable this feature in the system setup pro-  
gram before you can use FDISK. See your computer reference  
26  
Medalist 8421, 6421, 4311 and 2112, Rev. A  
guide for assistance. Be sure to re-enable this important fea-  
ture when FDISK is done.  
The system error message, “Drive not Ready,” appears.  
Check all cable connections. Make sure pin 1 of the drive is  
connected to pin 1 of the hard-disc controller or host adapter.  
Make sure the power supply is adequate for system needs.  
Reboot the computer and make sure the drive spins up.  
The FDISK error message, “No Fixed Disk Present,”  
appears.  
Make sure the power supply is adequate for system needs.  
Verify the drive-type values in the system setup program.  
Check for I/O address conflicts.  
The drive does not format to full capacity.  
Verify the drive-type values in the system setup program. One  
of the following problems may have occurred:  
The values may be set with an incorrect translation character-  
istic.  
You may have entered a parameter value that exceeds the  
physical capacity of the drive.  
You entered a translation characteristic that does not take full  
advantage of the drive’s capacity.  
The drive’s physical specifications exceed the translation limits  
imposed by the BIOS.  
Medalist 8421, 6421, 4311 and 2112, Rev. A  
27  
Caution. If you change the drive-type values in the  
system setup program, you must partition and format  
the drive again. This erases data on the drive.  
!
If you have partitioned the drive into individual logical drives,  
you may need to make the partitions smaller to access the full  
drive capacity.  
If your computer supports LBA mode, you may need to enable  
LBA mode in the system setup program to access the full  
capacity of the drive. Refer to your computer’s reference guide  
to find out how to enable LBA.  
The DOS message “Disk Boot Failure,” “Non-System Disk”  
or “No ROM Basic – SYSTEM HALTED” appears.  
Reinstall the DOS system files using the DOS SYS utility.  
Check all cables.  
Use FDISK to verify that the primary partition is active.  
Check for viruses.  
The system error message, “HDD controller failure”  
appears.  
Confirm the jumper settings on the drive.  
Verify the drive-type settings in the system setup program.

See your authorized Seagate distributor or dealer. Preinstalled  
or bundled software is provided “as is.” There are no warranties  
of merchantability or fitness for a particular purpose. All such  
warranties are expressly and specifically disclaimed.  
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.

Compliance of this drive, as a system component, was con-  
firmed with a test system. We cannot guarantee that your system  
will comply. The drive is not meant for external use (without prop-  
erly designed enclosure, shielded I/O cable, etc.).
