hello  everyone     i  got  a  sata  SSD  512 GB     in  not  detection    condition another  shop  already    have  try  to  recover  

it  have  03  Nand  chip are   same  but  01  Nand chip  is  different  

i  am  confused  is  it  replace  by   someone   ?

[Data Recovery Guru]

I doubt that someone swapped just one chip. What benefit would it be in doing that?

I think the chips are normal, especially if there are no signs of flux disturbed components around the NAND chips.

Could we see a photo of the whole PCB, both sides? Could we also see the
label?

I am trying to identify the date codes.

[compos mentis]

ACELW2242N38AH -> Intel/Micron N38A die, 2242 date code?

JKQXN38A2232-0801 -> Intel/Micron N38A die, 2232 date code?

EPI2210J031ABH / EPI2210J006HJT -> 2210 date code?

The correct part number appears to be PF29F01T2ALCQK1.

I found this 512GB SSD:

This CDI screenshot reports a serial number of YS20220710000302. I assume that the first digits are a YYYYMMDD date code, ie 2022-07-10.

https://lishuma.com/wp-content/uploads/2022/08/QQ%E6%88%AA%E5%9B%BE20220731170001.jpg

The NANDs are ...

  29F01T2ALCQK1
  EPI2206ZZ24752ABH
  581510623
  ACELW2226N38A-H

I suspect that the EPI date code, 2206, is some kind of initial date code.

The ACELW date code, 2226, appears to be a subsequent date code which precedes the manufacture date of the SSD by about 2 weeks.

To me, it looks like these chips are subjected to some in-house testing before the ACELW marking is added.
