Media Scan
Media Scan is used to examine drives and is able to detect the
presence of bad blocks. If any data blocks have not been properly
committed, data from those blocks are automatically recalculated,
retrieved and stored onto undamaged sectors. If bad blocks are
encountered on yet another drive during the rebuild process, the
block LBA (Logical Block Address) of those bad blocks will be
shown. If rebuild is carried out under this situation, rebuild will
continue with he unaffected sectors, salvaging a majority of the
stored data.
