Abstract
A data storage device is provided. The data storage device includes a flash memory and a controller. The flash memory stores a firmware. The firmware includes a plurality of mode page settings, and each mode page setting includes a plurality of mode parameters. The controller receives a mode selection command and a data out message arranged to rewrite a first mode page setting among the plurality of mode page settings from a host. The controller determines whether the data out message will change the mode parameters which cannot be rewritten in the first mode page setting according to the data out message. When the data out message will not change the mode parameters which cannot be rewritten in the first mode page setting, the controller determines whether a plurality of new mode parameters are kept in the flash after the data storage device is turned off.
