FCC notice
This equipment generates and uses radio frequency energy and, if not
installed and used in strict accordance with the manufacturer's instructions,
may cause interference to radio and television reception, which could void
the user's authority to operate the equipment. It has been tested and found
to comply with the limits for a Class B digital device pursuant to Part 15 of
FCC Rules, which are designed to provide reasonable protection against
such interference in a residential installation. However, there is no
guarantee that interference will not occur in a particular installation. If
interference does occur, try to correct it by taking one or more of the
following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the computer and the receiver.
•Connect the computer into an outlet on a circuit different from that to
which the receiver is connected.
•Consult the dealer or an experienced radio/television technician for help.
You may find the following booklet prepared by the Federal Communications
Commission helpful: How to Identify and Resolve Radio–TV Interference
Problems. This booklet (Stock No. 004-000-00345-4) is available from the
U.S. Government Printing Office, Washington, DC 20402. Further, this
equipment complies with the limits for Class B digital apparatus in
accordance with Canadian Radio Interference Regulations.
Cet appareil numérique de la classe B est conforme au Règlement sur

Scorpion 40 Installation Manual, Rev. A 3
Introduction
This installation manual summarizes the installation and
operation of Seagate®Scorpion 40 DDS-4 drives.
Note: DDS tape drives are sometimes referred to as “DAT”
drives. However, only the former term is used in this
manual.
The Scorpion 40 uses DDS-4 tape cartridges with a native
capacity of 20 Gbytes (40 Gbytes with 2:1 data
compression). It can also read and write older tapes using
DDS-1, DDS-2 and DDS-3 tape formats. Data compression is
supported for all these formats.
The Scorpion 40 supports the following SCSI interfaces:
•68-pin Ultra2 SCSI (LVD)
•68-pin SCSI Wide (single-ended)
•50-pin SCSI-2 (requires 68- to 50-pin single-ended
adapter such as Seagate PN 10006520-001)
Note: The Scorpion 40 will not work in a SCSI-1
environment.
The following Scorpion 40 models are covered in this manual:
Drive model number Form factor
STD1401LW 3.5-inch internal drive
STD2401LW 5.25-inch internal drive
STD6401LW External drive
Note. Additional or updated information on these drives may be
available on Seagate’s web site at www.seagate.com.
If you have purchased an external Scorpion 40, please turn to
page 15 for installation instructions. If you have purchased an
internal drive, continue to the next page.

Installing an internal Scorpion 40
Before you begin
!Caution. Observe the following precautions to avoid
electrostatic damage to the internal drive during
installation.
•Do not remove the drive from the antistatic bag until you
are ready to install it.
•Before you remove the drive from the antistatic bag,
touch a grounded metal surface to discharge any static
electricity buildup from your body.
•Hold the drive only by its edges and avoid direct contact
with any electronic components.
•If you need to put the drive down, lay it on top of the
antistatic bag or place it inside the bag.
Installation Overview
Internal drive installation involves three main steps:
1. Configuring the drive
2. Mounting the drive
3. Connecting the power and interface cables
Note: Internal Scorpion 40 drives come in different
configurations for mounting in 3.5-inch and 5.25-inch
drive bays. Drives configured for 5.25-inch bays are
identical to those used for 3.5-inch bays, but come
with mounting brackets and a wider face plate.
Installation procedures are the same for both drive
configurations.

Scorpion 40 Installation Manual, Rev. A 5
Configuring an internal Scorpion 40
Before you install the tape drive in your computer, you may
need to configure the drive’s SCSI ID or other drive features.
Jumpers located on the back of the drive (between the SCSI
interface and power connectors) are used to configure the
SCSI ID, parity checking, and termination power. Other drive
features are set using a bank of dip-switches on the
underside of the drive.
Default settings
The default drive settings for the Scorpion 40 are listed
below:
•SCSI ID: 6
•Media Recognition System (MRS) checking: enabled.
•Parity checking: enabled.
•Data compression: enabled.
•Power-on self-test diagnostics: enabled.
•Host operating system: Windows 95/98/NT/2000
•SCSI interface compatibility: Wide SCSI supported.
If these default settings are appropriate for your needs, skip
ahead to “Mounting an internal Scorpion 40” on page 10.
Jumper settings
Configuration jumpers on the back of the drive are used to
control the drive’s SCSI ID, parity checking, and SCSI
terminator power. The jumpers can also be used for remote
SCSI address selection. Figure 1 on the following page
shows the locations of the jumper blocks for the internal
Scorpion 40.

SCSI Address Selection (pins 1 through 8)
You can select the SCSI address used by the drive by
placing the appropriate jumpers on pins pairs 1-2 through
7-8, as shown in Figure 1. The SCSI address can also be
selected remotely by connecting a SCSI address-selection
switch to pins 1 through 8.

Scorpion 40 Installation Manual, Rev. A 7
Note: Each SCSI device on a bus must have a unique SCSI
ID. The SCSI controller or host adapter generally uses ID
7. In some systems, the boot drive uses ID 0 or ID 1.
Parity checking (pins 9 and 10)
If a jumper is installed on pins 9 and 10 (the default setting),
parity checking is enabled. If no jumper is installed, parity
checking is disabled, but parity is still generated by the drive.
Terminator power (pins 11 and 12)
Internal Scorpion 40 drives are shipped with terminator power
disabled (no jumper across pins 11 and 12, as shown in
Figure 1). You can enable terminator power, if necessary, by
placing a jumper across pins 11 and 12.
Note: The internal Scorpion 40 does
not
provide SCSI
termination, and therefore should not be installed as
the last device in a SCSI chain. See “SCSI
termination” on page 13 for more information.
If the terminator power jumper is installed, be careful not to
short the TERMPWR signal to ground. In the event of a
short, terminator power to the bus will be interrupted. After
the short is removed, a fuse in the drive will automatically
reset, restoring terminator power.
Dip-switch settings
Figure 2 on the following page shows the location of dip
switches on the
underside
of the Scorpion 40. Each of these
switches is described in detail on subsequent pages.
If you change a dip switch, the new setting will not take effect
until the drive is turned off and then on again.
