I was away and just saw your post, sorry for not getting back to you before.
I have just bought the WD and have updated it with the latest FW, which could be different from the manual of course.
I do recall however, seeing those settings the first time I was setting up the box, but I am not hunderd per cent sure as I had already read the manual so it could be just an impression.
Thanks for your help anyway, if you think of anything else please do get in touch as I have the nagging feeling that i might have done something wrong.
