ABSTRACT:
A disk drive can include a data storage disk, a head, an acceleration sensor, and a controller. The head is configured to write data on the disk. The acceleration sensor generates an acceleration signal that is indicative of acceleration of the disk drive. The controller determines when the disk drive is being subjected to a vibration condition determination. The controller can inhibit writing of data through the head onto the disk based on comparison of the acceleration signal to the threshold value.
