I have a new device, as above. It was working ok but then formatted it using ubuntu disk utility to boot manage to install windows on a partition.
Now the drive does not show on my desk top as usual. I would think I have removed some sandisk files that are needed to run the Fit device itself. The device now just flashes organge a few time and cannot be found to show anywhere on the OS.
I can I restore the device as it comes from the factory.
