Dear GUXM et al.

The reason for physical block 0 being used differently and reserved is that
it is the *only* block in NAND flash devices that the manufacturer
guarantees to be free of defects. All other blocks in the device are subject
to being mapped out at the foundry, or later in the field.

Check the documentation for your physical devices.

Cheers

Don
