The partition is not hidden and should show up. Did you password the disk when you setup the TC? If you did so you can sometimes get around it but I suspect the disk is just dead.. is it a Gen2 and the disk is a black caviar WD.. if so you are in deep bad stuff.
Do you have a windows computer available? Load a HFS viewer.. there are free ones available and see if the partition shows up.. if not the drive is dead and you will need to send to a recovery centre. Not a cheap or pleasant option as half the time the recovery seems to get rubbish.
