SETUP – MK2023GAS (HDD2187)

Caution: Your Hard Disk Drive is a precision device and even a small drop onto any surface can

cause damage. Electronstatic discharge can also damage the drive. You should ground yourself

prior to handling the drive.

Master/Slave Settings

Your Toshiba Hard Disk Drive can be configured as either a "Master" or "Slave" unit. 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 drive

as Master or Slave.

Master configuration is obtained by setting jumpers A, B, C & D open (no jumper present). 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".

Installation Notes

The drive should be mounted carefully on the surface of 0.1mm or less flatness to avoid excessive

distortion.

In order to prevent short-circuit under any circumstances, a space of 0.5mm or more should be

kept under the PCB.

Space should be kept around the drive to avoid any contact with other parts, which may occur

due to shock or vibration.

The temperature of the top cover and the base must always be kept under 60C to maintain the

required reliability.

Be sure not to cover the breathing hole to keep the pressure inside the drive at a certain level

Do not apply any force to the top cover, except the screw areas on top cover. Maximum force to

the specified area is 2N.

The drive contains several parts which may be easily damaged by ESD (Electric Static

Discharge). Avoid touching the interface connector pins and the surface of PCB. Be sure to use

ESD proof wrist strap when handling drive.

The four mounting screws should be tightened equally with 0.3N-m (3kgf-cm) torque. The depth

should be 3.0mm minimum and 3.5mm maximum.

Placing Hard Drive inside your Computer

•Determine mounting configuration (the drive can be mounted in either a horizontal or vertical

orientation)

•Configure drive for system application.

•Configure the adapter board for the specific system application (if required).

•Install adapter board into an unused PC/AT 16 bit slot (if required).

•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 strip.)

•Set correct drive type in system CMOS

•Refer to applicable manuals for software installation instructions.

Important Note: Disconnect power from your computer system before beginning installation.

USING THE HARD DISK DRIVE – MK2023GAS (HDD2187)

Backing up Data Files

To avoid data loss, regularly back up the data files on the hard disk drive.

TROUBLESHOOTING – MK2023GAS (HDD2187)

Problem Solution

My system is not able to recognize all available capacity

on my Hard Disk Drive. What do I need to do to utilize

the complete hard drive?

There are some systems that are unable to recognize the

new larger Hard Drives on the market. 3rd party software

is available that breaks the "capacity barrier". Some

suggestions are EZ Drive by Micro House and Disk

Manager DiskGo by Ontrack. Check with your local

computer/software supplier for availability or contact the

software manufacturer.

How do I install my 2.5" Toshiba Hard Drive into my

desktop or tower system?

You will need a HDD mounting kit in order to install a

Toshiba 2.5" drive into your desktop or tower system.

Contact your local computer supplier for kit availability.
