IMPORTANT SAFEGUARDS
For your protection, please read these
safety instructions completely before
operating the appliance, and keep this
manual for future reference.
Carefully observe all warnings,
precautions and instructions on the
appliance, or the one described in the
operating instructions and adhere to
them.
USE
Power Sources – This unit should be
operated only from the type of power
source indicated on the marking label.
If you are not sure of the type of
electrical power, consult your dealer or
local power company.
For the unit with a three-wire
grounding type ac plug:
If you are unable to insert the plug into
the outlet, contact your electrician to
have a suitable plug installed. Do not
defeat the safety purpose of the
grounding plug.
AC Power cord: (for AC mains
operating unit only)
The AC power cord should have
appropriate safety approvals or
marking for the country in which the
equipment will be used. Consult your
dealer or local power company.
Cleaning – Unplug the unit from the
wall outlet before cleaning or
polishing it. Do not use liquid
cleaners or aerosol cleaners.
Use a cloth lightly dampened with
water for cleaning the exterior of the
unit.
Object and Liquid Entry – Never
push objects of any kind into the unit
through openings as they may touch
dangerous voltage points or short out
parts that could result in a fire or
electric shock. Never spill liquid of
any kind on the unit.

4
INSTALLATION
Water and Moisture – Do not use
power-line operated units near water -
for example, near a bathtub,
washbowl, kitchen sink, or laundry
tub, in a wet basement, or near a
swimming pool, etc.
Power-Cord Protection – Route the
power cord so that it is not likely to be
walked on or pinched by items placed
upon or against them, paying
particular attention to the plugs,
receptacles, and the point where the
cord exits from the appliance.
Accessories – Do not place the unit on
an unstable cart, stand, tripod, bracket,
or table. The unit may fall, causing
serious injury to a child or an adult,
and serious damage to the unit. Use
only a cart stand tripod, bracket, or
table recommended by the
manufacturer.
Ventilation – The slots and openings
in the cabinet are provided for
necessary ventilation. To ensure
reliable operation of the unit, and to
protect it from overheating, these slots
and openings must never be blocked or
covered.
•Never cover the slots and openings
with a cloth or other materials.
•Never block the slots and openings
by placing the unit on a bed, sofa,
rug or other similar surface.
•Never place the unit in a confined
space, such as a bookcase, or built-
in cabinet, unless proper ventilation
is provided.
SERVICE
Damage Requiring Service – Unplug
the unit from the wall outlet and refer
servicing to qualified service
personnel under the following
conditions:
•When the power cord or plug is
damaged or frayed.
•If liquid has been spilled or objects
have fallen into the unit.
•If the unit has been exposed to rain
or water.
• If the unit has been subject to
excessive shock by being dropped,
or the cabinet has been damaged.
•If the unit does not operate normally
when following the operating
instructions. Adjust only those
controls that are specified in the
operating instructions. Improper
adjustment of other controls may
result in damage and will often
require extensive work by a
qualified technician to restore the
unit to normal operation.
•When the unit exhibits a distinct
change in performance - this
indicates a need for service.
Servicing – Do not attempt to service
the unit yourself as opening or
removing covers may expose you to
dangerous voltage or other hazards.
Refer to all servicing to qualified
service personnel.

Overview
The Sony SDX-450V and SDX-250V drives are high capacity data storage
devices using Advanced Intelligent tape (AIT) technology. The SDX-450V
and SDX-250V drives achieve high data reliability through Read-After-
Write, an additional level of Error Correction Code, and other features.
The Sony SDX-450V and SDX-250V drives store data on tape using
standard formats called AIT (Advanced Intelligent Tape) and ALDC
formats.

Introduction
About AIT Drives
The SDX-450V is an internal AIT drive unit that uses data cartridges
conforming to the AIT-1 Turbo format. The SDX-250V is an internal AIT
drive unit that uses data cartridges conforming to the AIT-E Turbo format.

The AIT Drive Unit SDX-250V has the following features:
•Supports reading and writing to data cartridges conforming to the AIT-E
Turbo format.
• The third-level error correction code guarantee high data reliability.
•Data compression provides 52 gigabytes of storage on 98 m tape-length
AIT-E Turbo data cartridge.*1
The native capacity is 20 gigabytes of storage on 98 m tape-length AIT-E
Turbo data cartridge.
•Stored data are automatically checked for compression.
•Wide Ultra SCSI LVD/SE interface is fully supported for host computer
access.
*1 This is assuming 2.6 : 1 compression ratio.
The degree of data compression attained while recording data varies according to
system environment and data type.

Precautions
Installation
Avoid placing the drive in a location subject to:
–high humidity
–high temperature
– mechanical shock and vibration
–direct sunlight
*For details, see “Specifications” on page 29.
Operation
•Do not move the drive while it is operating. It may cause malfunction.
• Avoid exposing the drive to sudden changes from a low to high
temperatures. This may cause water condensation to collect inside the
drive. If the ambient temperature should suddenly rise while the drive is
turned on, wait at least one hour before turning on the drive. If you
attempt to operate the drive immediately after a sudden increase in
temperature, a malfunction may occur.
•Turning off the power to the drive while they are writing to tape may
cause the tape to become unreadable. All previously negotiated
parameters will be lost, whenever power to the drive is cycled.
Transportation
•Keep the original packing materials to facilitate safe transportation of the
drive.
•Always remove the tape/media cartridge before moving the drive. After
removing the drive from the computer, repack the drive into its original
packing.

10
Useable Cartridges
The SDX-450V can be used with data cartridges marked with the AIT-E
Turbo, AIT-1 Turbo or AIT-1 logo.
The SDX-250V can be used with data cartridges marked with the AIT-E
Turbo logo.
Note
•Be sure to use only the cartridges designed specifically for AIT.
•Do not use anything but AIT cartridges with this system, as doing so can
damage the AIT drive. Although commercially available 8mm videotapes
resemble AIT cartridges in appearance, they have entirely different
specifications and cannot be used.
SCSI Termination
The SDX-450V and SDX-250V conform to the Microsoft PC97 standard,
which requires the internal (naked) drive to be terminated with an external
terminator.
Microsoft PC97 SCSI requirements
SCSI peripherals must not terminate the bus. Both internal and external
cable ends are instead terminated by plug-in connectors.

“CLEANING REQUEST” LED on the front panel lights after every 100
hours of operation.
When this LED lights, clean the drive with a head cleaning cartridge.
Note
To maintain the drive in optimum condition in environments affected by dust and other
contaminants, we recommend keeping cleaning requests enabled.
Terminator Power Control DIP switch
This DIP switch determines whether terminator power is supplied to the
SCSI bus. To enable terminator power, set position 5 [Terminator Power]
switch to ON.
Data Compression Control DIP switch
Data compression can be selected by DIP switches. Data compression is
enabled while position 7 [DC Control (1)] is ON. Control by host can be
disabled when position 8 [DC Control (2)] is ON.

Attaching and Removing the Dust
Cover
Attaching the Dust Cover
1Align the dust cover’s hinge clips (one on each side) with the
pins of the drive bezel.
•The dust cover should be positioned so that the magnets*
on the cover’s back face the drive bezel.
*This magnet does not affect the tape of the cartridge.
• Holding the dust cover at an angle as shown in the figure below,
set the hinge clips on top of the bezel pins, positioning them so that
they bracket the pins.

20
2Press down at an angle on each side in turn until you hear
the hinge clips click into place.
Caution
Do not press the dust cover in horizontally from the front. Doing so
could cause the dust cover to break.
3Close the dust cover.
This completes attachment of the dust cover.
