120GB SSD

AS2258-BN, looks that it is rebranded Phison PS3111 controller

4 - ID: 89 a4 08 32, read with config 2c a4 08 32
4 - dumps

page: 18560
block: 2304p
sector: 4640, 4096_12_532
XOR: FA9E80, 2304p

Dump was read on other reader (better quality), but with same config like in FE.
After I apply XOR from case I can see NTFS sructure etc. but XOR is not full.
This case could be similar to PS3110 layout families, but not sure.
I start uploading first dump. Please check it and make layout for ECC first. Than I upload rest.
Client is hurry with this case, so small request from my side Wink
Uploading dump.

Hmm, can I help you in some way? Will patterns help? Do you have XOR for full block?
