cruzer blade 8gb bricked out of box

i just bought a cruzer blade 8gb usb hard drive, but when i plug it into my computer, nothing happens, no new folders show up where a usb drive has appeared, and my computer doesn’t show any messages saying that an external memory card has been installed like usual, i think it’s bricked but if there’s anything you can do to help me, it would be appreciated.

Hi. Have you already all these steps?

If yes, try disable the U3 functionality. 

Blades don’t have U3.
