Travelstar E7K100 (Serial ATA) Hard Disk Drive Specification

31 

The disk drive withstands the following vibration levels without any loss or permanent damage.  

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.

Note: Overall RMS (root mean square) level of vibration is 29.50 m/sec2 (3.01G)

•

49 m/sec2 (5 G) (zero-to-peak), 10 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

The drive meets the following criteria while operating in the conditions described below. The shock test consists of 
10 shock inputs in each axis and direction for total of 60. There must be a delay between shock pulses long enough 
to allow the drive to complete all necessary error recovery procedures.
