Shock and vibration
Shock measurements are based on an 11 msec, half sine wave shock
pulse, not to be repeated more than twice per second. 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.
