The specifications in the table below are defined as follows: • During normal operating shock and vibration, the drive sustains no physical damage and reads and writes data without errors. • During abnormal operating shock and vibration, the drive sustains no physical damage, but performance is adversely affected. • During nonoperating shock and vibration, the read/write heads are in the shipping zone and the drive sustains no physical damage.
