Handling Precautions 

1. 

Do not press on the drive. 

Hold the drive by the sides only, do 

not apply any force to the drive during handling or installation 
 
2. Always handle the drive with care to prevent damage from 
shock, vibration or electrostatic discharge (ESD). Do not touch 
the Printed Circuit Board (PCB). 
 
3. 

Electrostatic Discharge. 

Static electricity can damage the 

drive. Before handling the drive, touch an unpainted metal 
surface for a few seconds to drain any static electricity from 
your body. 
 
4. Keep the original packaging and static -protective bag in case 
the drive has to be returned. 
 

 

 
Quick Installation Procedure 

 
It is advisable to backup all data before proceeding with the 
installation. 
If your system BIOS cannot handle large capacity drives (over 
540MB, or 8.4GB) you may need to use a disk overlay program 
such as Ontrack’s Disk Manager software. Contact your Hitachi 
supplier or the local Hitachi office. 

 
Dimensions / Screw locations 

Check that the dimensions and screw hole locations are correct for 
your system. 

 

 

 
 

 
Setting the jumpers 

 
1. In a one drive system configure the new drive as a Master with 
   no jumpers attached. 
 
2. In a two drive system, one drive must be designated as Master 
    and the other as Slave. 
 
3. When installing the new drive as a Slave set the jumper to 
   position A-B. Check the Master drive to determine if a jumper 
   change is required to indicate Slave present. 
 
4. Before selecting Cable Select (CSEL D-B) consult your system 
   manual to see if this is supported. 

 

 

 
 
Attaching the drive 

 
1. Turn off the computer, unplug the power cord and remove the 
    notebook battery. 
 
2. Open the cover. 
 
3. Match pin 1 of the 44 pin cable, usually denoted by a red 
    stripe, to pin 1 of the drive interface connector, shown above. 
 
4. Mount the drive securely using 4 M3 (metric) screws with a 
    maximum screw length of 2.5 mm. 

 
Configuring your computer 
 

1. Reinstall the notebook battery, plug in the power cord and turn 
    on the computer. 
 
2. The computer may detect a configuration change and prompt 
     you to proceed to the Setup screen. 
 
3. If it does not, enter the Setup screen using the key selection. 
    Refer to the onscreen instructions or the computer handbook. 
 
4. Select “Auto Detect” for the new drive, if your system supports 
    this feature. If it does not , select the “User Definable Type” 
    and enter the parameters from the table. 
 
5. If you cannot see the full capacity of the drive use Disk 
    Manager. 
 
6. Partition and Format the drive, then install your data. 

If, after complete installation, your system will not boot up,   
recheck all settings. If the system still fails to boot up, contact 
your supplier’s
