A disk drive is disclosed which has an event management function. At an event occurring time such as an error generation, the disk drive records the event information together with time data. A CPU of the disk drive is configured to, at a power ON time, allow the time data which is received from a host system to be stored in a memory. At the time of an error occurring, the CPU, while using the time measured by an internal timer and time data, generates time data which is synchronized with the internal time of the host system.
