not able copy or paste or format windows7

not able to copy format or paste any thing in my cruzer blade pendrive 8gb

I have the same problem, try various applications and has now been impossible to format, delete, or write to the drive

You need to isolate the issue first. Try out on another computer and see if it behaves the same. If yes, then check out with the store where you bought this from. 

hyyyy dude wat to check with store he says to complain to the product company sooo pzzz Dnt say to go


Tell the store you didn’t give money to the product company you gave it to him.  The product is flawed and you want your money back, from him.
