摘要
A technique for providing end-to-end data protection while supporting multiple cyclic-redundancy-check (CRC) algorithms includes receiving a data block protected by a first CRC. The first CRC is generated using a first CRC algorithm. The integrity of the data block is checked using the first CRC and the first CRC algorithm. A second CRC for the data block is then computed using a second CRC algorithm different from the first CRC algorithm. The data block, first CRC, and second CRC are stored on a storage medium, such as magnetic tape.
