Use Layout
SM2246 1094_48 LE4
to check ECC map

I think can try Test Retry

I meet such situation many times. Few sectors on beginning is ok, than all map is red. Try reread, RR mode and other tricks - not work. Data looks little strange. I meet this only with this controller family SM2246. No idea what is happen. Maybe controller damaged the data?

With layout
SM2246 1094_48 LE4 Xor 4983_256 v3

There is too much bit errors
ECC can not fix it

May be Retry commands do not work
