Claim Text:
1. A method for reading data from a tape drive, the method comprising: causing a record from a plurality of records stored on a tape inserted in a first tape drive to be read, each record from the plurality of records having a cyclic redundancy check (CRC) and an appended field of zeros, wherein the first tape drive does not support logical block protection (LBP) and removes the field of zeros appended to the record after insertion of the tape into the first tape drive and before transmitting the record and CRC to a data storage manager; appending zeros to the end of the received record after reading the record at the data storage manager; utilizing the CRC to check for data errors in the received record at the data storage manager; causing the tape to be moved to a second tape drive that supports LBP in response to instructions rendered by an application at the data storage manager; and causing the record to be read from the plurality of records at the second tape drive, wherein the data read at the second tape drive includes the record, the CRC, and the appended field of zeros.
