Abstract
A method for quickly detecting the state of a nonvolatile storage medium having a plurality of blocks therein is proposed. When the system stores data in any page of a blank block, the first page thereof is simultaneously marked. When there already is data in a block to be written in, because the first page of the block is already marked, it is not necessary to mark again. Therefore, it is only necessary to directly read the first page in each block when searching the block states in the nonvolatile storage medium. The state of the nonvolatile storage medium can be quickly detected based on the existence of a mark, hence effectively enhancing the performance of data access.
