That looked hopeful with the bottom line.  Also lsmod now has:

NATALIE:/home/julian# lsmod
Module                  Size  Used by
raw1394                31724  0

ohci1394               33924  1 dv1394
ieee1394              318772  3 raw1394,dv1394,ohci1394

However, then I tried this:

NATALIE:/home/julian# dvgrab foo-
raw1394 - failed to get handle: No such file or directory.

Is there something really obvious I've not done?

Unplug Dazzle -

NATALIE:/home/julian# cat /proc/kmsg
<7>ieee1394: Node changed: 0-01:1023 -> 0-00:1023
<7>ieee1394: Node suspended: ID:BUS[0-00:1023]  GUID[0003f30000005f96]

Plug it back in -

<7>ieee1394: Node changed: 0-00:1023 -> 0-01:1023

So the system is seeing it, therefore something is wrong with how it's
trying to access it.

I took the external HD down a friend's house yesterday and formatted
it NTFS to make sure the caddy works properly on another system.  That
formatted 100%.  Got home and plugged it in.  Now Windows doesn't even
see it.  I give up on that for a minute - one thing at a time :)

Kind regards,

Julian
