mtools doesn't work with drive a: . -- > mdir # returns : Syntax error at line 5 for drive A: column 0 in file /etc/mtools.conf: if you supply a geometry, you also must supply one of the 'format_omly' or 'filter' flags -- I added 'format_omly' at the end of that line ( and to the line for B: ) and it worked OK.
