6.5 Vibration and shock
All vibration and shock measurements in this section are for hard disk drives without mounting
attachments for systems. The input level shall be applied to the normal mounting points.
Vibration tests and shock tests are to be conducted by mounting the hard disk drive to a table using the
bottom or side four mounting holes.
6.5.1 Operating vibration
The hard disk drive will operate without a hard error while being subjected to the following vibration levels.
6.5.1.1 Random vibration
The test consists of 30 minutes of random vibration using the power spectral density (PSD) levels below.
The vibration test level is 6.57m/sec
