16 gb memory card unable to format

Hi, i bought sandisk card before 2 months on flipkart.Now i have an error in my card i copied a file into my card it transfered successfully after a few minutes is gone away… i deleted some file in sd card then it came back automatically. After this i tried different way of formatting by googling but nothing helped me. While formatting cmd it shows an error in create primary partition step it shows like allocation table error. Could you plsase help me.


in that case the card seems to be defective and it needs to be replaced with a new one
