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.

Abstract: A multiple field nonce particularly suited for use in encryption algorithms associated with data storage has at least one field unique to each data storage device to avoid the possibility of the same nonce value being used to store more than one data string. Additional fields may be based on the number of times at least one encryption key is associated with the storage device and on a number assigned to the particular string of data.

Abstract: A hand-held token for secure conveyance of encryption keys includes memory for holding a media key and at least one device key. Control logic reads the media key from memory, encrypts the media key based on the device key, and transmits the encrypted media key to a data storage device. The data storage device decrypts the encrypted media key using its own device key, which may have previously been downloaded from a token.
