INSTALLATION INSTRUCTIONS
Note: Toshiba’s 2.5” HDDs are primarily used in notebook devices. Installation into a
notebook varies depending on the system manufacturer. Toshiba’s 2.5” drives that
are installed into a desktop PC require a 3.5” installation kit.
1. Determine mounting configuration (can be mounted in either a horizontal or verti-
cal orientation).
2. Configure drive for system application.
3. Configure the adapter board for the specific system application (if required).
4. Install the I/F cable to the System’s 44 pin connector port or adapter board. Ensure Pin 1 is
oriented correctly. (Pin 1 on the cable is usually identified by a red or blue stripe.)
5. Refer to applicable manuals for software installation instructions.

Visually inspect the shipping container prior to unpacking for any signs of damage to the
container or its contents (the carrier is responsible for any damage incurred during ship-
ment). The drive is a precision device and even a small drop onto any surface can cause
damage. Prior to opening the anti-static bag, it is recommended that the user ground
himself with a ground strap or by touching the PC chassis or other metal object. Remove
the drive from the anti-static bag and check it for damage. Place the drive on the anti-
static bag while configuring jumpers to avoid any electrostatic discharge. Save the ship-
ping container and packing material for possible use later.
DRIVE CONFIGURATION
Toshiba’s 2.5" hard disk drives can be configured as either master or slave units. Master
configuration is used for all single drive applications, and master or slave configuration
(only one of each per port) is used for two drive applications. Use the information in the
following table before setting M/S drive.
Master configuration is obtained by setting jumpers B, C & D open (no jumper). Slave
configuration is obtained by setting jumpers C-D. When B-D jumper is installed, the
drive is configured as cable select. If pin 28 = Low, the drive is master. If pin 28 = High,
the drive is slave.
