This drive is a SCAM (SCSI Configured Auto Magically) compliant
drive. If the system into which you are installing this drive
requires SCAM compliant drives you do not need to be concerned about
the drive ID jumper settings, as the system automatically assigns
your new drive the ID it wants it to have. The system may or may not
use the existing drive ID jumper settings.
Before you physically mount your new disc drive in your computer,
you need to check the jumper plug settings that determine how the
drive operates (not true of SCAM compliant systems).
Note that there are some connector pins sticking out from the drive's
printed circuit board (PCB) that are labeled J2 and J6 (called
"jumper plug headers").
Models "W" and "WD" additionally have J1-Auxiliary. Some systems may
have a cable connected to J1-Auxiliary that allows remote setting of
drive ID by switches or within the computer logic. It also provides a
connection to a remote drive activity LED. Jumpers may be used on
J1-Auxiliary.
Note the small jumper plugs connected across pairs of pins in some
places on these connectors.
Note that the jumper plugs used on J2 are shaped differently and are
smaller than those used on J6 or J1-Auxiliary. Do not use J2 plugs on
J6 or J1-Auxiliary as this will damage the internal contacts so they
will not subsequently stay on J2.
The presence or absence of these jumper plugs in various places gives
your drive information about how it is to operate in your system
specifically. Each figure shows a diagram of one of these jumper
headers, together with a brief description of the operational feature
each jumper position controls.
If this is your first hard drive, or if it replaces your existing
hard drive, you may not need to reposition any jumpers. However,
check the figures against your drive to see if it is configured as it
should be for your system. Consult your computer documentation for
information on configuring your drive. Your dealer is the best source
for help on this. Seagate also provides support service for
customers if your dealer can't help.
Set Drive ID
------------
If your system is "SCAM" (SCSI Configured Auto Magically) compliant,
the system assigns the drive ID over the interface, so there is no
need to be concerned about drive ID.
Setting the drive ID jumpers doesn't hurt anything, but is not
necessary.
If your system is not "SCAM" compliant you do need to set the drive
ID using the ID jumpers.
Check your system documentation to see what ID it suggests you give
the drive.
We recommend that if your new drive will be the only hard drive,
assign it as "Drive ID 0," which requires no drive ID jumpers
installed. If your new drive is to be a second hard drive, assign it
as "Drive ID 1" by placing one of the extra jumper plugs supplied in
the enclosed plastic bag (one of the larger plugs) on the "Drive ID
1" position.
Double check drive ID settings for your drive or drives.
Select Operating Features
-------------------------
If your new drive replaces an existing drive, you must set up the new
drive to operate as the old drive did. Check the documentation for
your old drive to see how the drive was set to operate.
Normally, you should leave off the
"Delay Motor Start,"
"Enable Motor Start,"
"Write Protect,"
"Parity Disable," and
"Termpower to SCSI Bus" jumpers. A jumper on means the feature is
enabled, except for "Parity Disable," where a jumper on means that
parity checking is disabled. Only "Terminator Enable" and "Term Power
from drive" jumper positions should have a jumper on ("N" and "W"
models only).
Do not remove these two default jumpers or add jumpers to any of the
other jumper positions mentioned above unless your computer system
documentation indicates otherwise.
Factory installed default settings are generally always correct.
Drive models "WC" and "DC" plug directly into a bulkhead or PCB
mounted connector. Systems using these drives have made provisions
for terminators and selecting most options, so only "Write Protect"
and "Parity Disable" options (on J2) must be considered for possible
setting by a person installing a replacement drive (usually no
change is needed). Most systems using "WC" and "DC" model drives use
drives that have unique drive internal control firmware, so "off the
distributor shelf" drives probably will not work in these
installations. Firmware cannot be changed on these drives. If you are
upgrading by installing an additional drive, consult the system
documentation or system purchase source for help in setting up drive
ID, options, and getting termination correct.
I/O line terminators
--------------------
The SCSI I/O lines must be "terminated" at the drive connected to the
end of the cable. If your new drive is a model "N" or "W" and is to
be connected at the end of the cable. On J2, the "Terminator Power"
(TP) jumper should be left in the "Term. Power From Drive" position,
unless otherwise directed by your computer documentation.
If your drive is to be connected at the cable connector that is not
at the end of the cable (it is a second hard drive for your system),
the "Terminator Enable" jumper should not be installed. Remove and
store the jumper if there is one on the "Terminator Enable" position.
If your drive is a model "ND" or "WD" and is the last drive at the
end of the cable, an external terminator must be installed between
the I/O cable and the drive.
The external terminator may already be supplied with your system. If
not, one must be purchased at a computer equipment store.
The Terminator you have may not look exactly like the one in the
figure. The "Terminator Power to SCSI Bus" jumper must also be
installed in addition to the "Terminator power from Drive" jumper.
If installing a "WC" or "DC" model drive see system documentation.
These drives have no terminators, nor do they furnish terminator
power to the I/O bus. Terminators are in the Host system.

The drive will operate in all axis (6 directions).
Drive configuration
-------------------
You can easily install your new Seagate disc drive as your first ever
hard drive, a replacement or as a second drive in a computer system
with an existing hard disc drive.
Installation
involves the following steps:
- Drive configuration
- Mounting
- Informing the computer about your drive and how you want it divided
into partitions.
Note
This drive is a SCAM (SCSI Configured Auto Magically) compliant
drive. If the system into which you are installing this drive
requires SCAM compliant drives you do not need to be concerned about
the drive ID jumper settings, as the system automatically assigns
your new drive the ID it wants it to have. The system may or may not
use the existing drive ID jumper settings.
Before you physically mount your new disc drive in your computer,
you need to check the jumper plug settings that determine how the
drive operates (not true of SCAM compliant systems).
I/O line terminators
--------------------
The SCSI I/O lines must be "terminated" at the drive connected to the
end of the cable. If your new drive is a model "N" or "W" and is to
be connected at the end of the cable. On J2, the "Terminator Power"
(TP) jumper should be left in the "Term. Power From Drive" position,
unless otherwise directed by your computer documentation.
If your drive is to be connected at the cable connector that is not
at the end of the cable (it is a second hard drive for your system),
the "Terminator Enable" jumper should not be installed. Remove and
store the jumper if there is one on the "Terminator Enable" position.
If your drive is a model "ND" or "WD" and is the last drive at the
end of the cable, an external terminator must be installed between
the I/O cable and the drive.
The external terminator may already be supplied with your system. If
not, one must be purchased at a computer equipment store and
installed.
The "Terminator Power to SCSI Bus" jumper must also be installed in
addition to the "Terminator power from Drive" jumper.
If installing a "WC" or "DC" model drive see system documentation.
These drives have no terminators, nor do they furnish terminator
power to the I/O bus. Terminators are in the Host system.
Mounting the drive
------------------
Important Precautions:
- Make sure your computer is turned off before beginning
installation.
- Although switched off, your computer must remain plugged into an
electrical outlet with an earth ground. This minimizes the
possibility of damage from static discharge.
- Static electrical charges can accumulate quickly on people,
clothing and synthetic materials. The electrostatic fields due to
these charges when brought in close proximity to susceptible
circuit assemblies and components, can result in degraded
reliability or immediate failure of the affected component or
assembly.
- Always wear a grounded wrist strap. Attach the wrist strap to the
metal chassis of your computer. Use the antistatic pad as your work
surface, and avoid installation in areas with static-inducing
carpets.
1. Begin by removing the cover of the computer. Follow the
instructions in your computer manual. Systems that use "WC" and
"DC" drives probably do not require cover removal, as the drives
are mounted in a module that slides into place and plugs in.
2. Connect the 50 or 68 pin interface cable to the hard drive
interface connector on the SCSI host adapter card. Be careful not
to bend the pins on the host adapter card connector. Refer to your
SCSI host adapter manual for the location of the interface
connector.
The sockets on the interface cable must be matched correctly with
the pins on your SCSI host adapter interface connector. Verify the
location of pin 1 on the SCSI host adapter using your computer
system's manual. Pin 1 on the interface cable is indicated by the
stripe along the edge of the cable. Plug the cable into the hard
drive interface connector on your SCSI host adapter.
3. Thread the other end of the interface cable through your drive bay
and connect to the disc drive.
The sockets on the interface cable must be matched correctly with
the pins on the disc drive. Pin 1 on the interface cable is
indicated by the strip along the edge of the cable; pin 1 on the
Seagate disc drive is the pin closest to the HDA, on the side
closest to the four-pin power supply connector.
Plug the interface cable into the drive connector firmly
but carefully. The connector should cover both rows of pins.
If you are installing a second or multiple disc drives, repeat
this procedure using the additional drive connectors on the
interface cable.
4. Mount the drive in a drive bay.
- Direct mounting: The disc drive can be mounted in the drive bay in
any orientation permitted by the drive bay mechanical
configuration. Be careful not to over tighten the mounting screws.
Screws must not extend into the side drive mounting holes more than
0.015 inches, (9/64 inches) or into the bottom mounting holes 0.20
inches (3/16 inches). Purchase the four required 6-32 x 1/4 inch
screws at a hardware or drive supplier store.
- Using a special module: "WC" and "DC" drives should be fitted
with slides or most likely, mounted in a special module that
slides into the host equipment.
- Drive activity LED: If the drive mounts such that the drive
activity LED does not show when the computer cover is on, the
computer may provide for a remote LED two conductor cable to be
used on all models. This cable plugs into J6 on the front of the
drive.
"WC" and "DC" model drives have a line available in the J1-80 pin
interface. Check system documentation to see if J1 signal is used or
if a cable should be attached to J6.
5. Attach a system power cable to the power connector on each drive.
If your system does not have an extra power cable for the hard
drive, you can purchase a Y-shaped power cable.
6. Review each of the previous steps to verify that you have
completed the installation correctly.
7. Replace the cover on your computer.

4. The power supply must satisfy the safety requirements for SELV
(Safety Extra Low Voltage) circuits.
5. Service is to be provided by trained Seagate service personnel.
6. The incorporation of the disc drives listed in this guide into a
customer enclosure must meet the appropriate safety requirements
of the country in which it is used (e.g. UL 1950, CAN/CSA-C22.2
No. 950-M89, DIN VDE 0805:1993 and EN60950: 1992 (IEC 950).
Note
Power must be off when connecting or disconnecting.
Configuring the computer for your drive
---------------------------------------
The hardware part of your installation should now be complete.
Software installation informs your computer operating software about
your Seagate disc drive characteristics. You can then divide your
drive into partitions called "logical drives", if you want to,
although this is not necessary.
If you already have a hard disc drive on your computer and you are
installing a second drive, now is a good time to evaluate the status
and quality of your backups. Once you are satisfied with the status
of your backups, then proceed.
Note!
Seagate Technology assumes no responsibility for lost user data.
DOS Installation
----------------
To install your Seagate disc drive in your computer software, consult
your computer operating system documentation for assistance. Your
SCSI adapter card must be able to address the capacity of this drive.
Macintosh installation
----------------------
To configure this drive in a Macintosh system, you must use a
third-party hard disc initialization application. Most software
vendors and computer stores that carry Macintosh software will have
hard disc drivers available for purchase.
Follow the instructions provided with the disc initialization
application to complete the installation of your Seagate drive.
Note.
The Apple HD SC Setup utility included with your Macintosh system
software only works on drives ordered directly through Apple.
Unix installation
-----------------
There are several versions of the Unix operating system. Each of
these handle hard disc installation in a different manner. For this
reason, refer to your system's operation manual for information
about how to complete the installation of this disc drive. Contact
Seagate Technical support services for any additional information
needed to install the drive in a Unix system.
Other operating systems
-----------------------
Check your system documentation for instructions on installing new
drives.
