Sorry, can't help with the actual question, but it reminded me that when
one of my colleague's had a hard drive failure in his laptop he managed
to format his iPod while reinstalling Windows... he did think it
slightly odd that his 40GB HDD was only showing up as being 2GB :)

At a guess, the iPod identifies itself as such (on Windows plugging one
in automatically launches iTunes)
