Abstract: A method for managing queuing operations of a target device receiving commands issued by a host computer is disclosed. The target device is described as a disc drive having an ATA interface through which the commands are received. The interface includes queue for receiving and storing the commands. While in the queue, the commands are re-ordered for optimization. After being re-ordered, the disc drive checks the re-ordered arrangement of commands for overlap conditions. If, however, the disc drive detects a sequential command stream present in the commands transmitted from the host computer, the disc drive enters a sequential command processing mode wherein the commands of the sequential command stream forego queuing, and consequently, re-ordering and overlap checking, operations. Instead, these commands are performed in the order in which the commands are received by the disc drive.
