Need help to check this case

NOTES 1412:
1) I was able to create model for this case using Virtual Translator as well as find blocks already (attached to container by Job.txt) - after this got FAT, MBR and directory tree looks perfect but many files are demaged. I see many blocks without SA (FF FF FF) - can this be a reason ? Or maybe mistake in model ?

Are you able to verify if my model is correct ?

Only odd blocks

Block Pair 0x400000 Block Size => 0x800000
Join by Page 2 Block Size => Block Size * 2 = 0x800000 * 2 = 0x1000000
