6.5.6 6.5.7 Travelstar 5K160 (PATA) Hard Disk Drive Specification Swept sine vibration 49 m/ sec2 (5 G) (zero-to-peak), 5 to 500 to 10 Hz sine wave 0.5 oct/min sweep rate 25.4 mm (peak-to-peak) displacement, 5 to 10 to 5 Hz Operating shock The hard disk drive meets the criteria in the table below while operating under these conditions: The shock test consists of 10 shock inputs in each axis and direction for a total of 60. There must be a minimum delay of 3 seconds between shock pulses. The disk drive will operate without a hard error while subjected to the following half-sine shock pulse. Duration of 1 ms 1568 m/sec2 (160 G) Table 19. Operating shock Duration of 2 ms 3185 m/sec2 (325 G) The input level shall be applied to the normal disk drive subsystem mounting points used to secure the drive in a normal system. 6.5.8 Nonoperating shock The drive withstands the following half-sine shock pulse without any data loss or permanent damage. Duration of 1 ms 9800 m/sec2 (1000 G) Table 20. Nonoperating shock Duration of 11 ms 1470 m/sec2 (150 G) The shocks are applied for each direction of the drive for three mutually perpendicular axes, one axis at a time. Input levels are measured on a base plate where the drive is attached with four screws. 33/188
