6.8 Vibration and shock All vibration and shock measurements recorded in this section are made with a drive that has no mounting attachments for the systems. The input power for the measurements is applied to the normal drive mounting points. 6.8.1 Operating vibration 6.8.1.1 Random vibration The hard disk drive meets IBM Standard C-S 1-9711-002 (1990-03) for the V5L applied to horizontal direction and V4 applied to vertical direction. The test is 30 minutes of random vibration using the power spectral density (PSD) levels shown below in each of three mutually perpendicular axes. The disk drive will operate without non-recoverable errors when subjected to the above random vibration levels.

6.8 Vibration and shock
All vibration and shock measurements recorded in this section are made with a drive that has no mounting
attachments for the systems. The input power for the measurements is applied to the normal drive mount-
ing points.
6.8.1 Operating vibration
6.8.1.1
Random vibration
The hard disk drive meets IBM Standard C-S 1-9711-002 (1990-03) for the V5L applied to horizontal
direction and V4 applied to vertical direction. The test is 30 minutes of random vibration using the power
spectral density (PSD) levels shown below in each of three mutually perpendicular axes. The disk drive
will operate without non-recoverable errors when subjected to the above random vibration levels.

The drive will meet the criteria shown below while operating in the specified conditions:
!
No errors
occur with 0.5 G 0 to peak, 5 to 300 to 5 Hz sine wave, 0.5 oct/min sweep rate with
3-minute dwells at two major resonances
!
No data loss
occurs with 1 G 0 to peak, 5 to 300 to 5 Hz sine wave, 0.5 oct/min sweep rate with
3-minute dwells at two major resonances
6.8.2 Nonoperating vibration
The drive does not sustain permanent damage or loss of previously recorded data after being subjected to

Random vibration
The test consists of a random vibration applied for each of three mutually perpendicular axes with the time
duration of 10 minutes per axis. The PSD levels for the test simulate the shipping and relocation environ-
ment shown below.
