have a studio edition drive 2 tb. I purchased a 2 tb wd green drive to make it 3tb. i installed the drive and left my A drive in. when i restarted i screwed up and formated the 2tb hard drive. If I plug in it only shows the 2tb no 1tb and not seeming to self start . solid light in the front. can i undo what i did and start over? any suggestion on how to fix so i can get the 1 and 2tb drive to become my 3tb backup? THANKS!
