Sandisk Extreme 64GB - make it a fixed drive?

I just bought this flash drive and what do I find? That it doesn’t work as a Windows To Go host!

Didn’t read the Microsoft Windows to Go hardware webpage?

Years ago SanDisk did make a drive that was fixed for a short while but they stopped making them, I assume because there wasn’t enough demand for them.  And the architecture difference was much more than just flipping a bit.

Kingsten DataTraveler has an unofficial tool

Are you sure the “tool” isn’t just a driver to make the drive appear as a fixed drive, on the machine with the tool/driver installed?  Or are you talking about bootice?
