Abstract
A data storage device includes: a nonvolatile memory device comprising a plurality of memory blocks, each including a plurality of pages; and a controller suitable for controlling an operation of the nonvolatile memory device in response to a request from an external device, wherein the controller determines whether or not a memory block including damaged pages in which stored data are damaged occurs in the memory blocks, sets a memory block including the damaged pages to an invalid memory block based on the determination result, and regenerates free pages of the memory block set as the invalid memory block into a valid memory block.
