Abstract
A defect management method for a storage medium is provided. An initial check is performed on the storage medium, and then diving the storage medium into blocks, which at least include a using data area with endurance blocks. Each endurance block is given an initial endurance value. Then, an endurance table is established in the storage medium for recording endurance blocks and the initial endurance values. According to the endurance table, data is written to the storage medium based on its importance. When the writing cycles reach a predetermined times, the endurance values are recalculated and the table is updated accordingly. Data is then moved according to the new endurance values.
