Abstract: Systems and methods for managing errors on a magnetic tape having a plurality of partitions accessed by a tape drive having an associated tape drive processor in communication with a host computer having an associated host processor include receiving mapping information from the host computer that designates at least first and second logically adjacent partitions for reading/writing consecutive data, receiving a read/write request to transfer the consecutive data for the first and second partitions, detecting a data error when attempting to read/write the data for the second partition and communicating a corresponding data error message to the host computer, and receiving modified mapping information from the host computer that designates a third partition as logically adjacent to the first partition for reading/writing the consecutive data.
