I first tried it on my old desktop single boot with Kubuntu 10.10.
Absolutely nothing. Daughter's laptop (Vista) could see it OK, so
over to the dual boot machine. Here XP sees it. Kubuntu does not.

There was a small Windows file group that must have come with the
drive - so I removed them and tried again. Win properties says it is
formatted FAT32. So, I am bit puzzled but continuing to try sort it out.
