Tools & Methodology:

Flash Drive Information Extractor & ChipGenius -- Used to identify flash controller and NAND chip info.

H2testw (2 passes) -- Used to test drive capacity, functionality, and read/write performance.

Unraid USB Flash Creator -- Used to check local GUID compatibility (does not check against Unraid's live licensing server).

OSS Team U18 -- Used to measure idle current draw (mA) on a Windows PC (powered externally via USB-HID to eliminate meter self-consumption).

Additional Data Provided: Estimated year of manufacture and NAND flash lithography (node size).

Note: The Unraid USB Creator can be picky -- it may incorrectly flag some drives as having "No valid GUID" due to the non-standard length of their serial numbers.

The non-standard length should not be a problem when registering with the licensing server.

In the case of a completely missing serial number, running a vendor-specific tools like AlcorMP, JetFlash Online Recovery etc might resolve the issue.
