Travelstar 5K160 (SATA) Hard Disk Drive Specification
34/167
6.5 Vibration and shock
All vibration and shock measurements in this section are for drives without mounting attachments 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.
6.5.1 Operating vibration
The 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 6.57 m/sec
