Upload done

I could not find layout, so suspect software BB

Was unable to fix in FE myself, so did it in other SW

Page in FE is 9216, but page in other is 3x (27648) because it's TLC, right?

But 2 of 3 pages is garbage...

9216 Looks like garbage
9216 Looks like garbage
9216 Looks like real data
9216 Looks like garbage
9216 Looks like garbage
9216 Looks like real data
....
....


It's 16Gb device, but client says it's 4Gb

So I guess 2/3 pages unused, right?

With other reader and software I have removed BB and also extracted every 3rd page of 9216 from dump.

Dump looks more healthy and seems to fit layout "CBM2099 1040 Xor c32e_64"

Some green but a lot of red, so working on ECC.

Uploading this dump to container to see if it's worth proceeding any further.

I think it may need a block cut?
