Abstract
A data storage device includes a data protection system that protects data on a logical block address (LBA) level. In one implementation, the data protection system populates and maintains a global parity mesh table. The global parity mesh table includes parity information associated with a group of two LBAs. If data associated with one of the LBAs in the group becomes corrupted, the parity information in the global parity mesh table is used, in conjunction with data stored in the non-corrupted LBA, to recover the data associated with the corrupted LBA. In another implementation, the data protection system stores multiple copies of parity information in different sections or portions of two or more associated LBAs. If data associated with one LBA becomes corrupted, the data is recoverable using one of the copies of parity information stored in at least one or more of the associated LBAs.
