ABSTRACT:
A system includes a host first-in first-out (FIFO) module, a first encoder module, a control module, a disk FIFO module, and a second encoder module. The host FIFO module receives a block having data and selectively receives a host logical block address (HLBA). The first encoder module generates a first checksum based on the data and the HLBA and generates a first encoded block. The control module appends the HLBA to the first encoded block and generates an appended block. The disk FIFO module receives the block from the host FIFO module. The second encoder module selectively generates a second checksum based on the HLBA and the data in the block received by the disk FIFO module. The second encoder module compares the block received by the disk FIFO module to the block received by the host FIFO module based on the first and second checksums.
