each time i try to tranfer data to pen drive.. many folders with name "+++++" appear in the window of pen drive..
If i try to "safely remove hardware", then message pops up saying "The device cannot be stopped right now. try again later"
I cannot even format the pen drive. It says "Windows cannot format the pen drive. Quit any disk utilities that are accessing this drive" . But i'm not accessing the pen drive at that moment and even no window displaying its contents is opened
