Abstract
A storage system stores data in a primary block and a copy of the data in a secondary block. Parity bits are stored with the data and the copy of the data. A header with logical block information is stored with the copy of the data in the secondary block. The data in the primary block is not stored with a header, which allows more parity bits to be stored with the data in the primary block. This provides more robust error protection for the data stored in the primary block and reduces the need to rely upon the copy of the data in the secondary block.
