Can PM 8.0 merge a Logical with a Basic partition?

My hard-drive contains a basic partition and a logical partion.  When I save a file it is saved in both partitions.

 

a)  Is it possible to stop this from happening and if so how?  if not........

b)  Is it possible to combine the logical partition with the basic partion so there is only one partition and if so how?

 

Thank you.
