Unusable Sector
Initially, the HN29W12811 includes unusable sectors. The unusable sectors must be distinguished from the
usable sectors by the system as follows.
1. Check the partial invalid sectors in the devices on the system. The usable sectors were programmed the
following data. Refer to the flowchart “The Unusable Sector Indication Flow”.
