  • Flash type : SD
  • Brand : Lexar 2000x
  • Totall size: 128Gb
  • ID: 2c c4 08 32
  • Banks: 6
  • Channel: 1
  • Page: 18592
  • Structure: 16*(1024_126)/31
  • Sector: 1150
  • XOR: D7AF/2850
  • Layouts fits for ECC and gives FAT tables and MBR:
    SM2702 1150_31 Xor 2850
    SM2702 1150_31 Xor 2850_1024
    SM3257 1150_27 Xor 2850_128 BP-2048
    SM3257 1150_27 Xor 2850_256
    SM3257_41 1150_27 Xor 2850_384_256


NOTES 2449:
1) There are totall 6 crystals and each is 64Gb giving over 400Gb of data while real size of card is 128Gb (?1?!) - I know location of additional 2 crystals but they are not answering... no metter if we use NR or manual CE pull down
2) I see FAT tables, MBR parts at 0x40ffd4200 (01_02 ) and 0x16c800000 (01_04) but whetever combination I use I cannot get correct mix

Need your help

Dump repeats after each 0x480000000 with layout -> 0x51B400000 in raw dump -> 18 GB

2c c4 08 32 - is original chip ID?

Yes - this is original ID

This explain why it's marked 128GB..... 8 CE x 18Gb = 144 GB with SA and ECC. So looks like Lexar make those cards (128Gb/256Gb/400Gb) with same NAND capacity and ID and just increase by internal firmware card capacity

We got only 6 CE here - two are dead so real 6 x 18Gb = 108 Gb.... any luck with mix find ?

Config is complitly wrong

Need make new one from sctratch

But i have several models for this ID in library
http://www.flash-extractor.com/library/SM/SM3268/SM3268P-AB__2c_c4_08_32__1x1
http://www.flash-extractor.com/library/SM/SM3268/SM3268P-AB__2c_c4_08_32__1x1__v2
http://www.flash-extractor.com/library/SM/SM3281/SM3281L-AB__2c_c4_08_32__1x1

For me there is no reason to work on this case
Because i can not add it to FE
