Abstract
A data protection method for an electronic device having a storage medium is provided, wherein the storage medium includes a plurality of partitions and a partition table. In the data protection method, a partition entry point and a partition data corresponding to the specific partition are captured and sent to an external storage device when the electronic device enters a shutdown process. Then, the partition entry point is deleted from the partition table and the partition data is removed from the storage medium. When the electronic device is turned on, a user has to provide the corresponding external storage device to restore the partition entry point and the partition data back to the storage medium. Thereby, personal data stored in the storage medium is protected and accordingly data security is ensured.
Claims19
