Earnie's quite right with his description (of not only the problem and 
solution but also the note of the nice respite this question has had!;-))
One thing he didn't mention that's worth noting is that the initialization
which remounts / to c: only happens if you umount and try to remount outside
bash/sh (i.e. from the DOS prompt.)
