According to one embodiment of the present invention, a method of counteracting
gas ingestion in a hydrodynamic bearing of a spindle motor in a data storage device
comprises waiting for activity of a host connected with the data storage device
to become idle. When the activity of the host becomes idle, a determination is
made whether to release gas from a fluid of the hydrodynamic bearing of the spindle
motor. Responsive to determining to release gas from a fluid of the hydrodynamic
bearing of the spindle motor a motor spin down routine for the spindle motor is performed.
