SDT-9000 DDS-3 Tape Drive
Conglatulation on your purchase of the Sony DDS-3 drive SDT-9000.
This drive is a high capacity data storage device using 4mm DAT (Digital
Audio Tape) technology. The SDT-9000 drive achieves high data
reliability through Read-After-Write, an additional level of Error
Correction Code, and other features.
The Sony SDT-9000 drive stores data on tape using a standard format
called DDS (Digital Data Storage), DDS-3, DDS-2, DDS-DC and DCLZ
formats. These formats are used by many other DDS tape drive
manufacturers, providing a broad range of compatible tape drives.
The Sony SDT-9000 is fully READ and WRITE compatible with the DDS3, DDS-2, DDS and DDS-DC format tapes.

Precautions
Installation
Avoid placing the drive in a location subject to:
– high humidity
– high temperature
– mechanical shock and vibration
– direct sunlight
Operation
* Do not move the drive while it is operating. Doing so may cause a
malfunction.
* Avoid exposing the drive to sudden changes from low to high in
temperature. 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.
* Do not turn off the drive while a tape is inside the drive.
Transportation
* Keep the original packing materials for possible future shipments of the
drive.
* Be sure to remove any tapes from drive prior to transportation. After
removing the drive from the computer, repack the drive into its original
packaging.
