[Bug 1366538] Re: Synchronisation/close /dev/sdi: i/o error on target host

[Curtis Gedak]

These appear to be hardware errors.  You might check to ensure that all
cables are securely plugged in and then try again.

The output from the following command would also be useful:

    sudo parted -l

Status in “parted” package in Ubuntu:
  New

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.
