摘要： 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.
