The present invention provides a data storage device including a flash memory, a temperature sensor and a controller. The flash memory has a plurality of blocks, and each of the blocks has a plurality of pages. The temperature sensor detects surrounding ambient temperature to produce a temperature parameter. The controller is arranged to perform a first maintenance procedure after a predetermined period since the data storage device is powered on. The controller reads the temperature sensor to obtain a first temperature parameter in the first maintenance procedure and determines a first time span to perform a second maintenance procedure according to a first predetermined condition, wherein the first predetermined condition includes the first temperature parameter, and the controller is further arranged to perform the second maintenance procedure after the first time span since the first maintenance procedure has finished. Therefore, the data storage device may scan and update the blocks according to the current temperature. |
