Disk drive or any serial attached device logging a cable loss event

摘要

An information storage device is disclosed (such as a disk drive) comprising an interface for connecting to a host through a cable, and control circuitry for communicating with the host over the cable by executing a communication process. The communication processes comprises the steps of transmitting a communication request to the host over the cable and waiting to receive a response from the host over the cable. A cable loss event is logged if the host fails to respond after executing the communication process at least twice. Performing the communication process multiple times before logging a cable loss event helps ensure a communication failure is actually due to a faulty cable connection.
