Defect Flagging Strategy; Table 12: Pata Plist Physical Format - Hitachi HTS542525K9SA00 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 12: PATA Plist physical format

Defects are skipped without any constraint, such as track or cylinder boundary.
