8GB MicroSD

1 - ID: ec de 94 f3
1 - dump

page: 17920
block: 256p
sector: 1118_32
XOR: 17FE70, 256p

No layout found. ECC probably from SM3259 family. I check ECC in other software, it is not perfect, but please create layout so we can use read retry. Dump was read on other reader but should be same (size, block number like in FE). Uploading dump.

There is something strange with ECC

Do you fix ECC with other software?

I need original dumps (without ECC fix)

I know that, so I uploaded dumps without corrected ECC (maybe really small part on beginning of dump was check, but no more).
Maybe sector is 1117_1?

Select any layout with XOR 17fe

And look at 0x1e000000

There is no bit errors

Strange. To be sure, I read it once again and reupload.

Layout
SM3259 1118_31 Xor I 17fe_256 SA
added to FE_749

Look block with MBR
0x1fc000000 MBR
0x1fc098000 red ECC
0x1fc0ac000 red ECC

At pages with red ECC, Data and SA is not unxored
There is problem with reading of this pages
Can see them at ECC map

There is no mix

Block Number
Block Size 0x400000
Banks 0..7 / 0x000 / 0x0ff

Put attached image folder near dumps

Make Check Dirs
You will see increasing offset

Dir 0x02c0d000  Must be 0x02b81000  Diff+ 0x0008c000  Cluster 0x001783  
Dir 0x037b1000 Must be 0x0370d000 Diff+ 0x000a4000 Cluster 0x00230f
Dir 0x04f3f000 Must be 0x04e53000 Diff+ 0x000ec000 Cluster 0x003a55
Dir 0x065ea000 Must be 0x064b6000 Diff+ 0x00134000 Cluster 0x0050b8
Dir 0x07566000 Must be 0x07402000 Diff+ 0x00164000 Cluster 0x006004
Dir 0x08100000 Must be 0x07f78000 Diff+ 0x00188000 Cluster 0x006b7a
Dir 0x0e08c000 Must be 0x0dde4000 Diff+ 0x002a8000 Cluster 0x00c9e6
Dir 0x0e08f000 Must be 0x0dde7000 Diff+ 0x002a8000 Cluster 0x00c9e9
..
Dir 0x7e5e0000 Must be 0x7ce2c000 Diff+ 0x017b4000 Cluster 0x07ba2e


0x7e5e0000 / 0x400000 = 0x1F9
0x017b4000 / 0x1F9 = 0xC040
0xC040 / 0x4000 = 3

So need make Block_Cut
And cut 3 pages from each block

Thank you Sergey. It works. I corrected dump as much as possible and made model. Need cut first 3 pages from each block. No need insert "Image". Green dir structure Smile You can mark case as solved and close it. Model - tested:
