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 overall RMS (root mean square) level is 0.67 G for horizontal vibration and 0.56 G for vertical.
6.8.1.2 Swept sine vibration
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
the environment described below
6.8.2.1 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. See IBM STD C-H 1-9711-005.
The overall RMS (Root Mean Square) level of vibration is 1.04 G.
