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.
