So we see that in the second case, E: is not seen by Cygwin.  Does Windows show it to be mounted?  I 
am wondering if the difference is something about VBox and Windows not mounting E: in the second 
case, or if it is something about Cygwin not picking up on E: even if it _is_ mounted.  In the first 
case, it's not a Cygwin issue, but a Windows/VBox one.  In the second case, it's something about 
Cygwin, and we would want information about what Windows shows about the mounted E: share.
