"Safely Remove Drive" of Kingston 8GB flash drive produces "Unable to stop drive" error

[Adrian Frith]

Binary package hint: nautilus

When I use the "Safely Remove Drive" command on a Kingston 8GB flash drive (USB ID 0930:6544), the following error dialog appears:

"Unable to stop drive

Error detaching: helper exited with exit code 1: Detaching device /dev/sdb
USB device: /sys/devices/pci0000:00/0000:00:1d.7/usb2/2-3)
SYNCHRONIZE CACHE: synchronize cache(10): Fixed format, current; Sense key: Key=9
 Additional sense: Logical unit not ready, cause not reportable
  Info fld=0x0 [0]
FAILED: No such file or directory
(Continuing despite SYNCHRONIZE CACHE failure.)
STOP UNIT: start stop unit: transport: Host_status=0x07 [DID_ERROR]
Driver_status=0x00 [DRIVER_OK, SUGGEST_OK]

FAILED: No such file or directory"

The drive is unmounted but not completely removed; I can still see it in the "Computer" display in nautilus.

It only happens with this flash drive, and not with others.
