I have a i ball 2GB pen drive ,last week I have brought some stuff like 2-3 movies from my friends machine as I attached it to my machine it detected virus but my antivirus had quarantined it that time only.Now when I am whenever checking its properties its showing 1.32GB why so?Whenever I am trying to copy items in the pendrive its leaving some space in the pen drive and then the things are copied as if that much place has been already in use even though if I am scanning it with my antivirus its showing some files which are not visible in the drive.please tell me what should I do?I even tried to scan with 2-3 antivirus as well as I formated the pen drive.No use?
