6.5.2Nonoperating vibration
The disk drive withstands the following vibration levels without any loss or permanent damage.
6.5.2.1Random vibration
The test consists of a random vibration applied in each of three mutually perpendicular axes for a duration of 15 minutes per axis. The PSD levels for the test simulating the shipping and relocation environment is shown below.
Hz | (m2/sec4)/Hz |
2.5 | 0.096 |
5 | 2.88 |
40 | 1.73 |
500 | 1.73 |

6.5.3Operating shock
The hard disk drive meets the criteria in the table below while operating under these conditions:
ŸThe shock test consists of 10 shock inputs in each axis and direction for a total of 60.
ŸThere must be a minimum delay of 3 seconds between shock pulses.
ŸThe disk drive will operate without a hard error while subjected to the following
Duration of 1 ms
1960 m/sec2 (200 G)
Table 20. Operating shock
Duration of 2 ms
3920 m/sec2 (400 G)
The input level shall be applied to the normal disk drive subsystem mounting points used to secure the drive in a normal system.
6.5.4Nonoperating shock
The drive withstands the following half
Duration of 1 ms
9800 m/sec2 (1000 G)
Table 21. 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.
