I get the following message when I insert my pen drive to USB port. I am unable to format it as well. (This pen drive earlier used as a bootable drive for Ubuntu 12.04)

enter image description here

I am using Ubuntu 12.04 LTS.

lsusb command in the terminal gives the following message:

  • Plugin the USB stick.

  • Check the partition in the USB for errors:

sudo fsck /dev/sdb5
  • You might have to change the partition name (sdb5). Look in the error window again when you mount it.

I get this message: fsck from util-linux 2.20.1 e2fsck 1.42 (29-Nov-2011) fsck.ext2: Superblock invalid, trying backup blocks... fsck.ext2: Bad magic number in super-block while trying to open /dev/sdb5 The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> –  DUKE Oct 14 '12 at 9:29
    
make sure you're typing sdb5 and not sdb. The command should be: sudo fsck /dev/sdb5 –  green7 Oct 14 '12 at 11:09
    
if this doesn't work, try formatting the drive using gParted. –  green7 Oct 14 '12 at 11:10
