Thanks everyone for the replies!

When you say “no issues with the data” when read with VNR, what do you mean? Have you applied a suitable BCH to show that the memory is actually OK with 100% good ECC?
No suitable BCH found using VNR (even trying codeword analysis highest was like 20%) so havent been able to check 100% good ECC. Very strange. I saw mentioned some Kingston devices may be HW encrypted (with unique keys), could this be the cause of no suitable BCH?

How does USBDeview (or Device Manager) see the bare USB drive (without the NAND)?
USBDeview shows it as a USB Boot Loader - USB Mass Storage Device (VID: 0c76, PID: 2131) with no NAND on board.

You could also use "chip genius" to try and see what's going on.
I used usbflashinfo and it showed the following:
Volume: D:
Controller: Unknown
Possible Memory Chip(s): Not available
VID: 0C76
PID: 2131
Manufacturer: 3SYSTEM
Product: USB Boot Loader
Query Vendor ID: GENERIC
Query Product ID: USB Mass Storage
Query Product Revision: 1.25
Physical Disk Capacity: 10737418240 Bytes
Windows Disk Capacity: 0 Bytes
Internal Tags: SCAF-AADL
USB Version: 3.00
Declared Power: 296 mA
ContMeas ID: 9DB1-03-00
Done another read on a test device (with NAND also removed) and it also shows controller unknown.
