I have managed to get hal-device-manager working and it does indeed
show differences between the USB Stick and USB Disk, in particular

Stick
info.addons			    dbus.Array([dbus.String(u'hald-addon-storage')].....
storage.media_check_enabled    1
storage.removable		   1

Disk
info.addons			Does not exist
storage.media_check_enabled    0
storage.removable 		  0

It is also noticeable that when using the USB Stick and
Safely remove is invoked then /dev/sdx1 etc are removed
leaving just /dev/sdx then this device does not work.
ie
fdisk /dev/sdx fails to find the device


My knowledge runs out at this stage !!

Many thanks for the reply
