1.8.6.2 Nonoperating vibration

The following table lists the maximum nonoperating vibration that the drive may experience without incurring physical damage or degradation in performance when subsequently put into operation.

5–22 Hz	0.20-inch displacement (peak to peak)
22–350 Hz	5.0 Gs acceleration (zero to peak)

1.9 Drive acoustics

Drive acoustics were measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements are generally consistent with ISO document 7779. Sound power measurements were taken under essentially free-field conditions over a reflecting plane. For all tests, the drive was oriented with the cover facing upward.

For the Seek mode, the drive was placed in seek only. Currently for these drives, the approximate number of seeks per second is 26.6. The number of seeks per second is defined by the following equation:

Number of seeks per second = 0.4 / (average latency + average access time).

	Typical sound	Maximum sound
Mode	power (bels)	power (bels)
Idle	3.3	3.8
Read/Write	3.7	4.1

1.10 Electromagnetic susceptibility

The drive operates without errors when subjected to the following:

Radiated noise	≤ 3 volt/meter, 30 Hz to 500 MHz
Electrostatic discharge*	≤ 10 KVolts
Magnetic field strength	≤ 5 Gauss

*Electrostatic discharge susceptibility is measured with the drive mounted in a representative computer system (mounted to a ground plane with earth grounding). Discharges are applied to the bezel or other external surfaces on the ground plane.
