Hello again Graham,
I just did a little test recording in non-freesat mode.
Heres the output from my Ubuntu terminal session. The commands I issued are in bold type. My USB stick is named JUMPDRIVE and the mount command will show you where to find it.

Oops, you must have added your post about succeeding while I was busy writing this.
