Abstract
A data storage device includes a memory block relinking system. The memory block relinking system identifies memory blocks that have been identified as grown bad blocks. The memory block relinking system analyzes the memory blocks that have been identified as grown bad blocks to determine whether a sub-block of the memory block is salvageable. To determine whether the sub-block is salvageable, the memory block relinking system executes one or more operations on the sub-block. If the operation fails, the sub-block is retired. If the operation is successful, the memory block relinking system identifies the sub-block as a relinking candidate. The memory block relinking system logically links the sub-block that was identified as a relinking candidate with one or more other sub-blocks that were previously identified as relinking candidates to form a metablock.
