Hard Disk Drive (HDD) Handling Precautions
The HDD is a precision device for use in reading and writing
a large amount of data on or from a disk rotating at a high
speed. If it is not handled carefully, either abnormal opera-
tion may result or it may not be possible to read data. The
HDD is sensitive to the following items and special care is
required in safeguarding against them when handling an
HDD. Also take care in handling a set incorporating an HDD.
1 Hard disk drive assembly
2 Hard disk
3 Digital board assembly
<Note 1>
With due regard to operational considerations, remove the
parts located on the frame (Hard disk drive) together be-
fore removing the major parts.
<Note 2>
When attaching the hard disk drive assembly, be sure to
connect the earth wire.
<Note 3>
• When connecting or disconnecting the connector or wire,
take care not to damage them.
• When connecting the flat wire to the connector, be sure
to connect it in the correct orientation.
<Note 4>
When removing the board assembly, take care not to dam-
age it.
