"I have set the properties of the drive to "take no action." "
Just to make sure, you've done this for all types--pictures, music, mixed content, etc.?
I had sorta the opposite problem for awhile--I want my USB flash drives to ask me what to do. Two drives worked that way and one did nothing. I formatted the 'nothing' drive and no change. Then a couple weeks later it started behaving like the others. So maybe yours will start playing nice some time after you give up.
