I have seen these controllers on legit drives. I think they are real Phison.

@einstein9, I've never seen so many zeros in a JPEG file. Can I ask what hardware/software you used for your images? The quality is excellent, BTW.

NAND flash is a funny industry. It can be the really cheap NAND chips that make these drives cheap, or some strange business thing.. possibly fake controllers or just a company that is making 0.1% profit margin.

@einstein9 Have you run any tools against the drive to see what it reports? such as Chip Genius, GetFlashInfo.exe, Phison GetInfo (https://www.usbdev.ru/files/phison/getinfo/) or H2Testw for checking integrity?

@ HaQue i remember i bought those 4gb for less than 1$ (bulk)

i still have some new flashes 4,8gb as well

Flash now is detected but asking to format (partition gone by itself ) trying to access data not possible
