I was tired of this message popping up do to mistakes at the commandline that
I wrote a program that simply disables the B: drive so that such a message
doesn't appear.  Actually, I can disable/enable any DOS logical drive [a-z]
that I want with this program.

This is not a coding solution for your problem, just one way that I solved 
mine.
