scsi: handle flush errors properly
commit 89fb4cd1f717a871ef79fa7debbe840e3225cd54 upstream.
The culprit is the upgrade to 3.13.0-35. Until -34 it works fine. I am
trying the mainline kernels to see when the regression happens there.

In the mainline kernel (not really mainline, because it is an extended
version maintained by Canonical), the problem occurs between 3.13.11.5
and 3.13.11.6. I checked the git logs, but I am not expert enough to
understand which commit may be the cause of the problem. I'll try to git
bisect when I
I can add another data point: Same thing happened to me. I have a 300GB
external Seagate drive that was working fine for a few years with no
problems attached to the USB 2.0 port of my Gigabyte motherboard. After
upgrading to 14.04 with kernel 3.13.0-39-generic (64-bit) the drive

Just a comment about the text in bug description: the shred thing WAS
NOT about any workaround purpose, it was just what I first wanted to do
when I plugged the drive.

I confirm the problem also exists on Gentoo kernel 2.6.17. It seems to be an
old problem.
Is there someone have found an upstream bugreport in the kernel bugzilla ?

Without being able to troubleshoot the setup I can not say; I only know
that the kernel is saying there was a hardware error, so there's nothing
parted can do.

Yep, these are hardware errors; nothing to do with parted.
One of the many down sides to USB attached storage is that they do not
do proper error reporting so you can diagnose the problem. They simply
fail with no explanation.

I attached the drive on the pci host adapter : no error
I also tried to attach it with the usb adaptator to a usb2 mobo port instead of
an usb3 : errors again. The strange is that I don't get errors with the same
cable+usb adaptator when I plug that stack into my i386 12.04.4.

notice just at the moment of writing is that the 2 drives were genuine

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:
