Abstract
A reading method for solid-state disk returns data and/or information depending on state information. A data unit stored in the solid-state disk comprises metadata and a plurality of sectors including at least two sectors of user data, the metadata comprising a sector state set indicating state information of each of the sectors in the data unit, and the state information comprising a valid state and an invalid state. In response to receiving a read command from a host to read at least one of the sectors in the data unit, the solid-state disk returns actual data to the host for one or more of the sectors in the valid state, and returns information indicating a read error to the host for one or more of the sectors in the invalid state, according to the sector state set stored in the metadata of the data unit.
