Abstract
Embodiments of the invention increase the probability of error recovery in error recovery processing. When a reset command is received during an error recovery procedure (ERP), a timer is started in response to the reset command. From the time at which the reset command has been received until the predetermined time prescribed by the timer passes, the ERP step is continued. After the timer expires, the ERP processing stops on the completion of an ERP step M. Additionally, a HDD returns to a host a reset ready, which represents the completion of the reset. Since the ERP is continued even after the reset command is received, it is possible to increase the probability of error recovery.
