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.

Data compression (switches 1 and 2)
If switch 1 is ON (the default setting), hardware data
compression is enabled. If switch 1 is OFF, hardware data
compression is disabled.
If dip switch 2 is ON (the default setting) then SCSI
commands can be used to enable or disable hardware data
compression. To prevent hardware data compression from
being enabled or disabled by SCSI commands, set dip switch
2 to OFF.
Media-recognition system (switch 3)
The media-recognition system allows the drive to determine
whether a given tape cartridge conforms to the DDS tape
standard. Use of non-DDS media may appear to give
satisfactory results, but the inferior specifications of such
media can cause data-integrity problems.
Switch 3 enables or disables the media-recognition system
(MRS). If switch 3 is ON (the default setting), the drive reads

Scorpion 40 Installation Manual, Rev. A 9
and writes to MRS media and reads from but does not write
to non-MRS media. If switch 3 is OFF, the drive reads or
writes both MRS and non-MRS media.
Power-on self-test enable/disable (switch 4)
Switch 4 enables or disables execution of power-on self-test
diagnostics when the drive is powered on. If switch 4 is ON
(the default setting), the drive responds to SCSI commands
only after successful completion of the self-test (about 5
seconds). If switch 4 is OFF, the drive does not perform a
power-on self test.
Operating System configuration (switches 5 through 8)
Switches 5 through 8 are used to configure the drive for use
with UNIX and other non-Windows operating systems, as
described starting on page 25 of this manual. The default
setting for all four of these switches is ON.
SCSI Wide/Narrow (switch 9)
Switch 9 enables or disables SCSI Wide operation on the
SCSI bus. When switch 9 is ON (the default setting), the
drive is capable of operating in Wide (16-bit) SCSI mode.
When switch 9 is OFF, the drive will only operate as a
Narrow (8-bit) SCSI device.
Note: If switch 9 if set to OFF, the drive can only use SCSI
ID values 0 through 7.
Inquiry String (switch 10)
Switch 10 is used to select the Vendor ID that the drive
returns when queried with a SCSI Inquiry command. When
switch 10 is ON (the default setting), the Vendor ID will be
“SEAGATE DAT.” When switch 10 is OFF the Vendor ID will
be “ARCHIVE Python.” The “ARCHIVE Python” Vendor ID
may be used by independent software vendors to provide
software compatibility with previous Seagate DDS tape
drives.

Connecting the SCSI interface cable
Scorpion 40 drives can be used with three different types of
SCSI interfaces: Ultra2 SCSI (LVD), “Wide” (16-bit) single-
ended SCSI, and “Narrow” (8-bit) single-ended SCSI. The
drive can automatically detect whether it is connected to an
LVD or single-ended wide SCSI bus.
Note: The Scorpion 40 will not work in a SCSI-1
environment.
Connecting to a 68-pin Wide SCSI or LVD bus
To connect the drive to an LVD or SCSI wide bus, first turn
off all power to the drive and computer. Then attach the
interface cable to the SCSI interface connector on the back of
the drive (see Figure 5 below).

SCSI Termination
The internal Scorpion 40 does
not
provide SCSI termination.
For this reason, it should not be the last device on a SCSI
chain. Two termination examples are shown in Figure 6
below. If the drive is the only SCSI device, attach the drive to
the connector which is next to last on the SCSI chain and
attach a multi-mode terminator to the last connector in the
chain.

Attach a four-pin power cable to the power connector on the
back of the drive. Figure 7 on the following page shows the
location of the power connector.
The recommended 4-pin power connector for the internal
drive is an AMP 1-48024-0 housing with AMP 60617-1 pins
or equivalent.

Installing an external Scorpion 40
The external Scorpion 40 is a compact external drive that
connects to the host computer as a turnkey subsystem.
Installing the external drive involves three simple steps:
1. Configuring the drive
2. Connecting the SCSI interface cable
3. Connecting the power cord
Configuring the external Scorpion 40
The following is the default configuration for the external
Scorpion 40:
•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
•Termination power: supplied to the SCSI bus.
Note: Some of these configuration settings can be changed
using the SCSI Mode Select command. SCSI
command information for these drives is provided in
the product description manual.
Setting the SCSI ID
Make sure that the drive is turned off; then set the SCSI ID
for the drive using the push-button switch on the back of the
external drive. Figure 8 on the following page shows this
switch, as well as the two SCSI interface connectors, on/off
switch, and the power-cord connector.
Note: The drive must be restarted, or a bus reset must occur
for any change in SCSI ID to take effect.

Connecting the SCSI interface cable
The Scorpion 40 provides two 68-pin, shielded connectors on
the rear panel of the enclosure. Either connector can be used
as a SCSI IN or SCSI OUT connection (you can use either
connector to attach the drive to the host computer or to
another SCSI device).
Turn off your computer and all SCSI devices. Then attach a
SCSI cable from the host adapter or from another
(unterminated) SCSI device to the Scorpion 40
Note: The Scorpion 40 will not work in a SCSI-1
environment.
SCSI Termination
If the Scorpion 40 is the last device or the only device in a
SCSI chain, you must install a terminating plug on the unused
SCSI connector. See Figure 9 on the following page for two
SCSI termination examples. You can purchase a terminator
for the Scorpion 40 (part number 10006525-001) from
Seagate Express at 1-800-656-8419.
