WD Support replacing mybook live 3tb with mybook World II 4tb, few questions

Hi all, had the dreaded UI issue with the mybooklive 3tb and they are unable to ship me a replacement for that drive.  They offered me the 4tb mybook world which I accepted.  When I receive this, is there anything I really need to do right out of the box(ie turn on ssh like I failed to do for the mybookworld.)  Just want to be able to recover data/access the drive or avoid any of the shortcomings that you all may have noted to date.  Thanks in advance

Put in an RMA for my drive just after xmas and they called today and offered to upgrade to the mybook world 4tb… Will see how it goes. 

I’d never take a MBW over a MBL, but at least you got an extra TB…
