Abstract
A data storage device including a non-volatile memory and a micro-controller is provided. The non-volatile memory includes a plurality of data blocks. The micro-controller selects one of the data blocks as a source block and another one of the data blocks as a destination block. Also, the micro-controller duplicates data in the source block to the destination block, and when the data is corrupted and unrecoverable, stores an unrecoverable-error bit corresponding to the data into the destination block.
