6.0 Physical Format
Media defects are remapped to the next available sector during the Format Process in manufacturing. The mapping from Log-
ical Block Address (LBA) to the physical Block locations is calculated using internally maintained tables.
6.1 Shipped Format (P-List)
• Data areas are optimally used.
• All pushes generated by defects are absorbed by available tracks of the inner notch.
P-List Physical Format
Note: Defects are skipped without any constraint, such as track or cylinder boundary. The calculation from LBA to physical
is done automatically by internal table.
6.2 Reassigned Format (G-List)
• G-List has a capacity of 5000 Customer LBAs.
• Multiple reassignments of the same Customer LBA do not increase the number of G-List entries.
• A track for spare sectors is inserted after every 800 nominal customer tracks.
