Abstract:
A drive apparatus of the present invention includes a recording/reproduction section and a drive control section. The drive control section at least performs a process including: performing an RMW process of reproducing data recorded in an original ECC cluster including the location specified by the recording instruction, modifying at least a portion of the reproduced data, and recording the modified data in a replacement ECC cluster; determining whether or not there is any physical sector, in which the reproduction of data has failed, in the original ECC cluster in the RMW process; and setting status information value in status information of replacement management information when it is determined that there is any physical sector, in which the reproduction of data has failed, in the original ECC cluster in the RMW process, the status information value indicating that there is any physical sector, in which the reproduction of data has failed, in the original ECC cluster, the status information indicating that the original ECC cluster is replaced with the replacement ECC cluster.
