5.0 Defect flagging strategy
Media defects are remapped to the next available sector during the Format Process in manufacturing.
The mapping from LBA to the physical locations is calculated by an internally maintained table.

Ÿ Data areas are optimally used.
Ÿ No extra sector is wasted as a spare throughout user data areas.
Ÿ All pushes generated by defects are absorbed by spare tracks of inner zone.

Defects are skipped without any constraint, such as track or cylinder boundary. The calculation from LBA
to physical is done automatically by internal table.
Note: It is possible to reallocate sectors during drive usage including sectors damaged during the early
period of usage. Reallocation of sectors is primarily caused by handling problems and is a normal main-
tenance function performed by the hard disk drive.
