WD 1TB cannot join active directory in windows server 2008

Hello I bought an external WD 1TB my book ethernet and i cannot join to active directory in windows server 2008. I tried everything i have found inside in other posts but yet nothing. The firmware is updated in the latest firmware according to info of the hdd

As far as I know the MBW has the option to join to a domain simply because it uses the same interface and OS as the Sharespace but the controller is not the same and the option really doesn’t work that well if it ever does.
