Safety cautions for this product

Caution

0.2.1This product is not authorized for use in life support devices or other applications which pose a significant risk of personal injury.

0.2.2Handle the drive with care not to suffer bodily injury caused by hitting the edge of the frame or accidental dropping of the drive.

0.2.3Since the drive uses glass media for the disk platter, opening of HDA may cause bodily injury. Warranty void in case of opened HDA or any broken HDA seals. Do not open the HDA or break any HDA seals.

0.2.4Temperature of the drive may become more than 50°C. Handle the drive carefully not to get burned.

Caution

0.2.5To prevent data from being lost due to an unexpected fatal error, data back up is required.

0.2.6If a foreign conductive substance (metallic powder, fluid, etc.) adheres to active metal of the drive (Print pattern, component lead, etc. on Printed Circuit Board (PCB)), it may cause catastrophic failures. Customer should protect the drive from the above condition.

0.2.7Improper insertion of connector or wrong jumper setting may cause catastrophic failures. Referring to this manual prior to the connector insertion or jumper setting can help insure correct insertion.

0.2.8Follow the environmental conditions and power requirement described in this manual. If violating these specifications, the drive failure may occur.

0.2.9Protect the drive against Electro Static Discharge (ESD) during handling.

0.2.10If storage period becomes long after unpacking, supply power to the drive and rotate the disks 8 minutes or more. This operation shall be executed every 3 months.
