Thanks. I don't know if my 160 Gig hard drive would qualify as a
modern *large* disk or not, but it's definitely bigger than the
current 20 Gig one.  I thought an external USB drive would work fine,
but I'm finding the current situation is too cramped.

Is there any way to mount an LVM partition from another Linux distribution?
