Seagate ST36450A ユーザーズマニュアル

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 Seagate drive for cable select, place a jumper on pins 5 and 6 and
pins 7 and 8 as shown below.

You can connect a remote LED to pins 3 (–) and 4 (+) as shown in the
figure below. Do not install a jumper on these pins. Because the jumper
block uses a 0.1-inch connector, you may need to replace the current
connector. Use Seagate connector part number 10562-001 or  equivalent.

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 Manager 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.

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 automatically 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 procedure allows you to boot from a diskette and still access
your hard drive.

Boot the computer from the hard disc (with no diskette in the
diskette drive).

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, then loads the
operating system. See the Disk Manager online manual for more
information about creating a dynamic drive overlay boot diskette.

The Disk Manager dynamic drive overlay provides support for drives
that have capacities greater than 528 Mbytes under  MS-DOS, Windows
3.

x,

 Windows 95, Windows NT 3.51, Window 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). 

Disk Manager does not support 32-bit

FAT in Windows 95.

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.

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,
you will lose access to the full capacity of your drive unless you have
another method for accessing high-capacity drives (see 

Addressing

Drive-Capacity Limitations

 on the front side of this sheet). Follow the

instructions below to remove a DDO from a drive.

Caution.  Before you attempt to remove a DDO,
make a backup copy of all the data on your hard
disc. Also, run CHKDSK, SCANDISK or a third-
party equivalent to detect and repair any damaged
files before you follow the procedure below. 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.

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 Manager.

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

shown for your drive in the table in Section 2, “Configuring Your
Computer,” on the front side of this sheet. Save your changes and
exit the system setup program.

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.

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 take 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 secured with mounting screws.

•

Check all connectors and cables. Make sure all ribbon and power cables
are securely connected. Ribbon cables are easily damaged, especially at
the connector. Try a new cable known to be good. Make sure no
connector pins are bent. Verify that pin 1 on the interface cable is aligned
with pin 1 on the drive and host adapter (see figures and instructions on
the front of this sheet).

•

Verify jumper settings. Review the instructions on this sheet 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 computer’s internal power
supply can support the total power demand. If necessary, consult your
dealer for a new power supply.

•

Verify the drive-type settings in the system setup program. The drive-
type settings in the system BIOS must not exceed the physical
specifications of your drive. Also, the 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.

If you have performed the preceding basic checks but the problem persists,
follow these guidelines for troubleshooting specific cases.

•

Check your computer manual or BIOS manufacturer to determine
whether your BIOS supports drives that have more than 4,096 cylinders.
If your system has this limitation, use the following procedure to
configure your computer:

1 Turn off your computer, open the case, and remove your new

Seagate drive.

Caution.  To avoid electrostatic discharge damage to
your computer or hard drive, make sure you are
well-grounded before touching the drive, cable,
connector or jumpers.

2 Place a jumper on pins 1 and 2 on the master/slave jumper block as

shown below. This enables the alternate capacity option that causes the
drive to appear to your BIOS as having a 2.1-Gbyte capacity.

3 Remount your drive in the computer and replace the computer cover.

4 Insert a bootable DOS diskette into drive A and turn on the computer. It

should boot from drive A and automatically detect the new drive as a
2.1-Gbyte drive.

5 Insert your DiscWizard diskette into drive A and type A:\DM. Then

press 

ENTER

. This runs the Disk Manager program.

6 Follow the Disk Manager instructions to install the dynamic drive overlay

and to partition and format your new drive to its full capacity.

7 After Disk Manager is done, reboot your system. You should see the

Disk Manager banner and be able to access the full capacity of your new
drive.

If the steps listed above do not remedy this problem, try the following:

•

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.

•

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 discs reach operating
speed. If the drive motor does not start up, recheck all drive cables.

•

Verify that for each drive, a drive-type is listed in the system 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 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, verify that the drive
and host adapter are compatible with your computer. 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 computer, 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” instructions under “Advanced Disk Manager Options.”

•

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 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.

•

Check all cables.

•

Your DOS diskette may be corrupted. Try using a backup DOS 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 system. You must disable this
feature in the system setup program before you can use FDISK. See your
computer reference guide for assistance. Be sure to re-enable this
important feature when FDISK is done.

•

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.

•

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.

•

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 characteristic.

 – You may have entered a parameter value that exceeds the physical

capacity of the drive.

 – You entered a translation characteristic that does not take advantage of

the drive’s full capacity.

 – The drive’s physical specifications exceed the translation limits imposed

by the BIOS.

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.

•

Your computer may not support drives that have more than 4,096
cylinders. Follow the instructions for 

After you install your new drive, your

computer will not boot, and no error message shows on the screen

.

•

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.

•

Confirm the jumper settings on the drive.

•

Verify the drive-type settings in the system setup program.

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 under Windows 3.1, install the Seagate replacement 32-bit access
driver, SEG32BIT.386, located on your DiscWizard diskette.

Note. If you install Windows 3.1 on a high-capacity
hard drive, the first time you start Windows you may
see a message suggesting that you disable 32-bit
