    Abstract: A data protection method applied to a data storage device including a volatile memory and a non-volatile flash memory is provided. The data protection method includes, executing a protection program after the data storage device is coupled to a host, to perform following steps: shielding a refresh command from the host; monitoring a working voltage of the data storage device through a voltage sensing module; determining whether the working voltage is lower than a threshold; when it is determined that the working voltage is lower than the threshold, providing the data storage device with power to trigger the refresh command to write the data in the volatile memory into the non-volatile flash memory. Therefore, the writing times of the data storage device are reduced, the performance degradation of the data storage device is avoided, and the service life of the data storage device is extended.

    Abstract: The invention introduces a method for handling sudden power off recovery, performed by a processing unit of an electronic apparatus, to include: driving a flash interface to program data sent by a host into pseudo single-level cell (pSLC) blocks of multiple logical unit numbers (LUNs) in a single-level cell (SLC) mode with multiple channels after detecting that the electronic apparatus has suffered a sudden power off (SPO). The pSLC blocks are reserved from being written any data in regular operations until the SPO is detected.
