Well, mounting the device in Dolphin, I can see the data.  Oops - now I 
realise that it was the Windows data partition that I was seeing.  There is a 
second 'Volume' in Dolphin, and clicking on that bounces immediately to 'home' 
(still in Places).  This is the location '/media/-home' which contains only 
lost+found.  Clicking on that brings the message 'Could not enter folder 
/media/-home/lost+found'.  Entering it as root it says that there are 0 items.

Qtparted sees only my hard drive.  I think this output from fdisk refers to 
it, though:

Disk /dev/mmcblk1: 7969 MB, 7969177600 bytes
255 heads, 63 sectors/track, 968 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000eb694

        Device Boot      Start         End      Blocks   Id  System

Disk /dev/dm-0: 1134 MB, 1134560256 bytes
255 heads, 63 sectors/track, 137 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

Disk /dev/dm-0 doesn't contain a valid partition table

Fdisk and formatting is one place where I do not experiment :-), too 
dangerous, so I welcome advice from someone with more experience.

I have used fdisk to prepare an empty disk, but this is definitely beyond my 
experience level.
