Abstract

A data storage apparatus has a transmission interface, a nonvolatile memory and a controller. The controller records a non-completed flag. When the controller starts a card opening process, the nonvolatile memory is configured under card opening, and the non-completed flag is set non-completed status. When the controller receives a format command form the transmission interface, the nonvolatile memory is formatted and the non-completed flag is set as completed status. When the controller receives a write command, the write data are scrambled before being written to the nonvolatile memory. When in non-completed status, when the controller receives a read command from the transmission interface, no matter whether the data corresponding to the requested address are scrambled, the data are descrambled and descrambled are provided via the transmission interface.
