My drives aren´t mapped correctly:
C: and D: are Flash drives - O.K.
E: is the DVD Drive <--this is omitted
Well, E: is in fact there, but it shows the content of the Harddrive F:.
F: shoes the content of patition G:
G: shows the content of H:
and H: shows no content although it is present as a Drive letter..

So, DVD drive is missing and contents of HD-Partitions are all shown one drive letter up.
