Abstract
A data storage device includes a memory device and a controller. The controller is configured to select a source block, read metadata associated with the source block and compare to a logical block address to physical block address (L2P) table, determine if a flash management unit (FMU) of the source block is valid, and add a new entry associated with the FMU into a valid FMU buffer when the FMU of the source block is determined to be valid. The controller is further configured to determine that the source block has been fully validated and select a next source block based on a valid counter. The valid counter corresponds to an amount of valid data of the next source block.
