Emergency disk creation - drivers

[OldNavyGuy]

I have used Rufus to burn the ISO to the troublesome USB and it worked.  For some reason, Hasleo itself does not like that particular USB and the Hasleo guys have admitted defeat, as, understandably, they have more important things to be getting on with.

To be clear, are you not able to boot with the USB, or are you trying to back up to the USB, and you can't see it?

Honestly, the easiest test would be to simply reformat the drive as NTFS.
