I just got the same Error when I attached my new external HDD case. Strange is, I didn't get this error with the same HDD in my old case. The new case is a "fantec DB-ALU3" and it has USB 3.0. The old case was a "Conrad Electronic" Model No.: "CEX-HDD/U35s" with USB 2. The HDD is a WD 1TB with serial-ATA.
The exact error message is: Error detaching: helper exited with exit code 1: Detaching device /dev/sdb USB device: /sys/devices/pci0000:00/0000:00:1d.7/usb1/1-3) SYNCHRONIZE CACHE: FAILED: No such file or directory (Continuing despite SYNCHRONIZE CACHE failure.)
