Physical Format; Shipped Format - IBM DTTA-351010 - Deskstar 10.1 GB Hard Drive Specifications

5.0 Physical Format

Media defects are remapped to the next available sector during Format Process in manufacturing.
mapping from LBA to the physical locations is calculated by an internal maintained table.

5.1 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 spare tracks of inner zone.
N N + 1
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: There is possibility to reallocate sectors during drive usage including early period. It is mainly caused
| by handling problem, and the reallocation is normal maintenance work of Hard Disk Drive.
