A data storage device includes a flash memory and a controller device. The flash memory includes a plurality of pages, wherein each of the pages includes a spare area, and each of the spare areas stores a power-off-reset count. The controller device determines whether the first page has been through a power-interruption event according to the power-off-reset counts stored in the spare areas.
