Umm interesting. You mean it occurs controller error before ecc error
at power loss case.
And it needs to define the terminology the Sudden Power Off Recovery
or POR shortly.
I'm not sure a previous powerloss means POR.

Anyway could you show the controller error value? Since it needs to
distinguish others e.g., initial bad blocks condition.

Thank you,
