6.6 Vibration and shock

All vibration and shock measurements in this section are for hard disk drives without mounting attach-
ments for systems. The input level shall be applied to the normal drive mounting points.
Vibration tests and shock tests are to be conducted by mounting the drive to a table using the bottom four
mounting holes.

6.6.1 Operating vibration

The disk drive will operate without a hard error while being subjected to the following vibration levels.
6.6.1.1 Random vibration
The test will be 30 minutes of random vibration using the power spectral density (PSD) levels below. The
vibration test level is 0.67 G RMS (Root Mean Square).
