Thank you all.
Although it seems many people reported an ordinary SATA drive in WD Element & MyBook, I’ve read somewhere a user got a native USB for the Element (I think a user in amazon…I forgot) , so I decided to avoid them for now.
I’ve also read the password & hardware encryption make the drive unreadable & impossible to salvage the data without the original case.
So, I’ve ended up buying an internal HDD (WD Green 2TB EZRX) with an independant USB 3.0 enclosure.
As I speak, my desktop comp is backing up 940GB of data to the external drive right now.
Thanks again all.
