If there is an immediate need to update the offline attributes, the HDD slows down and the offline attributes get updated. The latest "S.M.A.R.T." technology not only monitors hard drive activities but adds failure prevention by attempting to detect and repair sector errors.
Many errors are detected and corrected by the hard disk drives using the ECC codes [17] which are stored on disk for each sector. If the disk drive detects multiple read errors on a sector it may make a copy of the failing sector on another part of the disk, by remapping the failed sector of the disk to a spare sector without the involvement of ...
