Hello guys, I want to investigate, what are the flash drive solutions (controller types) that you cannot solve at present? As we all know that China mass-produces and uses cheap flash drives, those strange controllers are usually difficult to support by the support center, and the drive algorithm is usually very different. Currently I can solve a small number of difficult projects.

Hi,
Some of them cannot be solved due to conditio of NAND Dump ,Some are encrypting Controllers ,I have come across one that cannot be solved ,I have arranged a donor for transplant NAND or NAND + Controller To Other PCB .

This is the second USB drive that I have, and both have resulted in the same issue that I can't solve. I received a 64GB extreme USB drive and as soon as I tried to copy files the copy failed and the system froze up. I could read the files on the drive just fine. So I tried to format the drive using the exFAT file system but the format fails every time. It almost appears like the drive is write protected or the drive shuts off and stops communicating after a few seconds. This is the second drive that I have, and both have resulted in the same issue.

Well,
You Are Doing Logical Recovery ,We Are Talking Chipoff Physical Recovery here . This might be a bad nand cells case

Why did you try to reformat it?

Because ,
Most of Them Think They Need To Format And Then Recover Data Lolz

This is a plague on the internet, and this info keeps spreading. I call then 'honey-pots', many of the data recovery software (Stellar, WonderShare, Nucleus, CleverFiles) have literally 100s of pages trying to score on specific google searches, say something like 'corrupt sd card'.

Because (f*cking stupid) Google values content, even if the content is utter bullshit, they cook up some story and tips to address the issue, like 'corrupt sd card', and the advise frequently includes check-disking, formatting and whatnot. And of course at some point the page then tries to make the sale for the file recovery software they're selling.
