I get this error in Nautilus:
"Unable to stop 2 TB Hard Disk
Error detaching: helper exited with exit code 1: Detaching device /dev/sdc
USB device: /sys/devices/pci0000:00/0000:00:1c.2/0000:02:00.0/usb3/3-3)
SYNCHRONIZE CACHE: FAILED: No such file or directory
(Continuing despite SYNCHRONIZE CACHE failure.)
STOP UNIT: FAILED: No such file or directory"

The error only occurs, when I select "Safely Remove Drive" from the context menu. (In Nautilus I have selected the pane "Places" on the left side of the window. There the drive is shown. There the context menu was opened). After the error occured, the drive is removed (the eject button vanished).

The error DOES NOT OCCUR if I click on the eject symbol on the right of the device name. This works fine.

Software:
  Ubuntu 11.04 with latest updates,
  Nautilus 2.32.2.1
Hardware:
  2 TB HDD SAMSUNG HD203WI
  External USB 3.0 HDD Case by "Sinan Power".

One info from "hdparm -I /dev/sdc":
Configuration:
 cache/buffer size = unknown

Conclusions:
1.) The cache is said to be "unknown" by hddparm and nautilus' error message said "SYNCHRONIZE CACHE: FAILED: No such file or directory". Is there a correlation? Maybe the hdd-cache is not used, therefore there's no file, but Nautilus expects one?

2.) What does Nautilus do different when using the eject button (which works) in contrary to using the context menu entry "Safely Remove Drive" (which does not work)?

3.) Has it something to do with USB 3.0 maybe?
