Thanks for finding correct thread

it seems that your disk is connected and recognized properly. Maybe You're trying to do everything little too fast? Don't click "mount" just 0,5 second after enumerating. wait 3-4 seconds, then try it.

Also, post here please how You try to mount it manually from xterm (as a root, of course?), and what output You receive.

And, don't worry. You will get it working - it's recognized properly, so it's only matter of some small mistake, I'm 100% sure about that
