First need find layouts that match by XOR
This controllers xor SA

Select layout
Select place with green ECC in middle of dump
ECC = Off
Set Jump size = 0x2000 (page size)
Press and hold ctrl + page_down

Look on SA
if see random bytes, then xor not match

Do it some time. May be 10 seconds

Check all layouts with this method

@bryan: correctly unXORed SA will change only few bytes (header and LBN). In case if you choose wrong layout then SA are still XORed and whole SA is just pack of randon bytes (noise).
