[Bug 1368299] Re: External USB hard drive format fails

[brad haack]

After formatting under 12.04, I didn't try to use the disk under 14.04 in a plain ext* format...
While running 12.04 I ran 'cryptsetup luksFormat',  which ran successfully, I wrote a couple of files and read them.  Then back in 14.04, similar to before,  couldn't read the disk.  I could mount it, but dmesg had the same msg as before which looked like a hardware issue:
[  891.562667] end_request: critical target error, dev sdb, sector 0
[  891.564060] end_request: critical target error, dev sdb, sector 97525840
[  891.564075] Aborting journal on device dm-2-8.
[  898.397620] EXT4-fs error (device dm-2): ext4_journal_check_start:56: Detected aborted journal
[  898.397628] EXT4-fs (dm-2): Remounting filesystem read-only

Title:
  External USB hard drive format fails

Status in “gparted” package in Ubuntu:
  Invalid

Bug description:
  Trying to reformat Maxtor USB external hard drive.  This was formated with an encrypted partition, but since I was having trouble accessing that I thought I would start over clean.
  When running gparted there are numorous errors but it get to the end and says successfully completed.  I tried GPT and DOS with an ext4 partition.  Same result either way.
  Here is a sampling of the errors I see when gparted is running:
  (gpartedbin:3879): GLib-CRITICAL **: Source ID 7 was not found when attempting to remove it
  Error fsyncing/closing /dev/sdb: Remote I/O error
  Remote I/O error during write on /dev/sdb

  I mounted the file system with this line in fstab:
  /dev/sdb1                                  /media/Maxtor1  ext4 defaults
  sudo mount /dev/sdb1

  This is the tail of dmesg
  [ 8875.215909] end_request: critical target error, dev sdb, sector 0
  [ 8965.547040] EXT4-fs (sdb1): mounted filesystem with ordered data mode. Opts: (null)
