That certainly says that /dev/sdc is the Kobo's storage. What
happens if you do

sudo mount /dev/sdc /mnt

please cut and paste.

Do I need a Windows/DOS driver of some sort? Or has something else gone wrong?

Typical! I'm sure I tried that yesterday, but anyway it mounts
manually perfectly OK now. So all I'm missing is the automatic
mounting.

... and that's just in settings. While I'm here what's the difference between:-

Mount removable drives when hot-plugged
and:-
Mount removable media when inserted

A USB stick is a removable drive. A DVD is removable media.

A USB stick is a removable drive. A DVD is removable media.

So I guess my Kobo is 'removable media' because it used to automount
itself in /media/chris.

Thanks.

Oh, no. That's another category. Dan is correct, but the terms "media"
and (external) "drive" aren't used correctly all the time, alas.

The mount points under /media/<user> seem to be customary for most DEs regardless of whether you mount a medium or a drive :-)

Cheers
