Bug description:
  Ubuntu 14.04.1 x86-64
  wanting to unmout a pata drive (usb attached), I get this (title) "Warning from libparted" when gparted launches.
  Same issue with another pc x86-64
  Errors retries then ignore, shred /dev/sdi fails:

  shred: /dev/sdi : pass 1/2 (random)…
  shred: /dev/sdi : pass 1/2 (random)…231MiB/94GiB 0 %
  shred: /dev/sdi : failure of fdatasync: i/o error on target host

  I reached to shred the drive from a 12.04.4 i386 pc with no error.
