A bad block identifying method for a flash memory, a storage system, and a controller thereof are provided. The bad block identifying method includes determining whether a programming error occurs in a block of the flash memory after the block is programmed and marking the block as a bad block when the programming error successively occurs in the block. Since the block is determined to be a bad block only when the programming error repeatedly occurs in the block, misjudgment of bad block in the flash memory can be avoided and accordingly the lifespan of the flash memory storage system can be prolonged.
