UBI even tries to recover from such a situation. If only the EC header is bad,
it will create a new one. Only of the VID header is bad/missing and the payload
is corrupted (ECC errors or bit-flips) it will erase it.

A missing VID header plus good payload will cause UBI to stop attaching since it
violates the IO model.
