Defect Flagging Strategy; Table 15.Plist Physical Format - Hitachi T7K250 - Deskstar - Hard Drive Specifications

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.
Shipped format
• Data areas are optimally used.
• No extra sector is wasted as a spare throughout user data areas.
• All pushes generated by defects are absorbed by the spare tracks of the inner zone.
Table 15: Plist physical format
Defects are skipped without any constraint, such as track or cylinder boundary.
