If a drive being connected cant get the letter assigned to it by diskmgmt.msc it just grabs some available letter. Years of use, XP now Win 7, my desktop mapping drives to 3 or 4 other desktops and 2 laptops. And on my desktop 2 eSATA drives, 4 or 5 USB drives. A USB chip reader coming and going. It creates 4 drive letters. Other USB drives and jump drives coming and going.
