A method for accessing data of a redundant array of independent disks (RAID), wherein the redundant array of independent disks comprises a plurality of disks, the plurality of disks being associated with a data accessing device, the method being executed by the data accessing device, the method comprising:
reading data from at least one disk among the plurality of disks;
detecting whether a lookup table stored on a memory is empty, the lookup table storing information indicating data loss;
comparing, in response to detecting that the lookup table is not empty, data read information associated with the read data with table items in the lookup table to determine whether there is a table item in the lookup table that matches the data read information; and
sending, in response to determining that there is a table item that matches the data read information, the information indicating data loss.
