My research indicates that you can use your choice of file system.  I've
found references to both FAT and ext2 being used.

This set off a train of thought.  It seems that the kernel is simply
failing to recognise it as a device which might have partitions on it. 
Fdisk can see the partition but it isn't making it into the system
partition tables.  I'm not too worried about destroying media because
they seem to be about 3 GBP each, complete with caddy.

I tried "mke2fs /dev/hdc" and that worked fine.  I can then mount the
disk and copy files on and off.

I'd still be interested if anyone knows of any documentation for it.

Cheers,
John
