I have a USB and for some reason i can't access it. 
On `fdisk -l` i don't see the USB, also not show on gparted or anywhere.... 

I don't remember the format of the usb.

Gparted and Disks also fail to find the drive.

Any ideas ?

I recreate I think how i failed the USB, but i want to tell if i can rescue it.

I was burn with dd some iso and because it was stack i kill the process and then it can't mount or see with fdisk -l.

Why this happens if you know ? I destroy the firmware ? 

Sorry i am stupid :) :P

Cheers
