hi! i'm a newbie on Windows Home Server. i just want to ask if i add my current 640gb with all my files on it to WHS, will all of its contents be erased? i don't have additional drives to backup all of it's contents and i just want to have all of my files centralized so i can access it anytime without the risk of losing it just by plugging it i've read that if you add drive, it will ask if you want it to be added to WHS space. if you answered yes, the drive will be formatted. thanks.
